■ - If swallowed do NOT induce vomiting.
- If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to
maintain open airway and prevent aspiration.
- Observe the patient carefully.
- Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming
- Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.
- Seek medical advice.
- Avoid giving milk or oils.
- Avoid giving alcohol.
- If spontaneous vomiting appears imminent or occurs, hold patient's head down, lower than their hips to help
avoid possible aspiration of vomitus.
■ If this product comes in contact with the eyes:
- Wash out immediately with fresh running water.
- Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by
occasionally lifting the upper and lower lids.
- Seek medical attention without delay; if pain persists or recurs seek medical attention.
- Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.
■ If skin contact occurs:
- Immediately remove all contaminated clothing, including footwear.
- Flush skin and hair with running water (and soap if available).

- Lay patient down. Keep warm and rested.
- Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures.
- Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
- Transport to hospital, or doctor.
■ For acute or short term repeated exposures to petroleum distillates or related hydrocarbons:
- Primary threat to life, from pure petroleum distillate ingestion and/or inhalation, is respiratory failure.
- Patients should be quickly evaluated for signs of respiratory distress (e.g. cyanosis, tachypnoea,
intercostal retraction, obtundation) and given oxygen. Patients with inadequate tidal volumes or poor
arterial blood gases (pO2 50 mm Hg) should be intubated.
- Arrhythmias complicate some hydrocarbon ingestion and/or inhalation and electrocardiographic evidence of
myocardial injury has been reported; intravenous lines and cardiac monitors should be established in
obviously symptomatic patients. The lungs excrete inhaled solvents, so that hyperventilation improves
- A chest x-ray should be taken immediately after stabilisation of breathing and circulation to document
aspiration and detect the presence of pneumothorax.
- Epinephrine (adrenalin) is not recommended for treatment of bronchospasm because of potential myocardial
sensitisation to catecholamines. Inhaled cardioselective bronchodilators (e.g. Alupent, Salbutamol) are the
preferred agents, with aminophylline a second choice.
- Lavage is indicated in patients who require decontamination; ensure use of cuffed endotracheal tube in
adult patients. [Ellenhorn and Barceloux: Medical Toxicology].
Any material aspirated during vomiting may produce lung injury. Therefore emesis should not be induced
mechanically or pharmacologically. Mechanical means should be used if it is considered necessary to evacuate
the stomach contents; these include gastric lavage after endotracheal intubation. If spontaneous vomiting has
occurred after ingestion, the patient should be monitored for difficult breathing, as adverse effects of
aspiration into the lungs may be delayed up to 48 hours.
for naphthalene intoxication: Naphthalene requires hepatic and microsomal activation prior to the production
of toxic effects. Liver microsomes catalyse the initial synthesis of the reactive 1,2-epoxide intermediate
which is subsequently oxidised to naphthalene dihydrodiol and alpha-naphthol. The 2-naphthoquinones are
thought to produce haemolysis, the 1,2-naphthoquinones are thought to be responsible for producing cataracts
in rabbits, and the glutathione-adducts of naphthalene-1,2-oxide are probably responsible for pulmonary
toxicity. Suggested treatment regime:
Induce emesis and/or perform gastric lavage with large amounts of warm water where oral poisoning is suspected.
- Instill a saline cathartic such as magnesium or sodium sulfate in water (15 to 30g).
- Demulcents such as milk, egg white, gelatin, or other protein solutions may be useful after the stomach isemptied but oils should be avoided because they promote absorption.
- If eyes/skin contaminated, flush with warm water followed by the application of a bland ointment.
- Severe anaemia, due to haemolysis, may require small repeated blood transfusions, preferably with red cellsfrom a non-sensitive individual.
- Where intravascular haemolysis, with haemoglobinuria occurs, protect the kidneys by promoting a brisk flowof dilute urine with, for example, an osmotic diuretic such as mannitol. It may be useful to alkalinise theurine with small amounts of sodium bicarbonate but many researchers doubt whether this prevents blockage ofthe renal tubules.

■ Sensory irritants are chemicals that produce temporary and undesirable side-effects on the eyes, nose or throat. Historically occupational exposure standards for these irritants have been based on observation ofworkers' responses to various airborne concentrations. Present day expectations require that nearly everyindividual should be protected against even minor sensory irritation and exposure standards are establishedusing uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no-observable-effect-levels (NOEL) are used to determine these limits where human results are unavailable. An additional approach,typically used by the TLV committee (USA) in determining respiratory standards for this group of chemicals,has been to assign ceiling values (TLV C) to rapidly acting irritants and to assign short-term exposurelimits (TLV STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints combineto warrant such a limit. In contrast the MAK Commission (Germany) uses a five-category system based onintensive odour, local irritation, and elimination half-life. However this system is being replaced to beconsistent with the European Union (EU) Scientific Committee for Occupational Exposure Limits (SCOEL); thisis more closely allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:- cause inflammation- cause increased susceptibility to other irritants and infectious agents- lead to permanent injury or dysfunction- permit greater absorption of hazardous substances and- acclimate the worker to the irritant warning properties of these substances thus increasing the risk of ■ For trimethyl benzene as mixed isomers (of unstated proportions)Odour Threshold Value: 2.4 ppm (detection)Use care in interpreting effects as a single isomer or other isomer mix. Trimethylbenzene is an eye, nose and respiratory irritant. High concentrations cause central nervous system depression. Exposed workers showCNS changes, asthmatic bronchitis and blood dyscrasias at 60 ppm. The TLV-TWA is thought to be protectiveagainst the significant risk of CNS excitation, asthmatic bronchitis and blood dyscrasias associated withexposures above the limit.

■ - Safety glasses with side shields.
- Chemical goggles.
- Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A
written policy document, describing the wearing of lens or restrictions on use, should be created for each
workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals
in use and an account of injury experience. Medical and first-aid personnel should be trained in their
removal and suitable equipment should be readily available. In the event of chemical exposure, begin eye
irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at the first
signs of eye redness or irritation - lens should be removed in a clean environment only after workers have
washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS 1336 or national equivalent].
■ - Wear chemical protective gloves, eg. PVC.
- Wear safety footwear or safety gumboots, eg. Rubber.
Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves
- frequency and duration of contact,
- chemical resistance of glove material,
- glove thickness and
- dexterity
Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739, AS/NZS 2161.1 or national

■ Cartridge respirators should never be used for emergency ingress or in areas of unknown vapour
concentrations or oxygen content. The wearer must be warned to leave the contaminated area immediately on
detecting any odours through the respirator. The odour may indicate that the mask is not functioning properly,
that the vapour concentration is too high, or that the mask is not properly fitted. Because of these
limitations, only restricted use of cartridge respirators is considered appropriate.
The local concentration of material, quantity and conditions of use determine the type of personal protectiveequipment required. For further information consult site specific CHEMWATCH data (if available), or yourOccupational Health and Safety Advisor.
■ Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-
designed engineering controls can be highly effective in protecting workers and will typically be independent
of worker interactions to provide this high level of protection.
The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker
and ventilation that strategically "adds" and "removes" air in the work environment. Ventilation can remove
or dilute an air contaminant if designed properly. The design of a ventilation system must match the
particular process and chemical or contaminant in use.
Employers may need to use multiple types of controls to prevent employee overexposure.
Local exhaust ventilation usually required. If risk of overexposure exists, wear approved respirator. Correctfit is essential to obtain adequate protection. Supplied-air type respirator may be required in specialcircumstances. Correct fit is essential to ensure adequate protection.
An approved self contained breathing apparatus (SCBA) may be required in some situations.
Provide adequate ventilation in warehouse or closed storage area.

■ - Presence of incompatible materials.
- Product is considered stable.
- Hazardous polymerisation will not occur.
For incompatible materials - refer to Section 7 - Handling and Storage.
■ Accidental ingestion of the material may be damaging to the health of the individual.
Ingestion of petroleum hydrocarbons can irritate the pharynx, oesophagus, stomach and small intestine, and
cause swellings and ulcers of the mucous. Symptoms include a burning mouth and throat; larger amounts can
cause nausea and vomiting, narcosis, weakness, dizziness, slow and shallow breathing, abdominal swelling,
unconsciousness and convulsions. Damage to the heart muscle can produce heart beat irregularities,
ventricular fibrillation (fatal) and ECG changes. The central nervous system can be depressed. Light species
can cause a sharp tingling of the tongue and cause loss of sensation there. Aspiration can cause cough,
gagging, pneumonia with swelling and bleeding.
Ingestion of naphthalene and related compounds may produce abdominal cramps with nausea, vomiting, diarrhoea,
headache, profuse sweating, listlessness, confusion, and in severe poisonings, coma with or without
convulsions. Irritation of the bladder may also occur, producing urgency, painful urination, and the passage
of brown or black urine with or without albumin or casts. Severe naphthalene can result in haemoglobin
appearing in the urine, methaemoglobinaemia, which causes oxygen starvation, and death. Methaemoglobinaemia
is characterised by cyanosis (a bluish discolouration of skin and mucous membranes) and breathing
difficulties. Symptoms may not occur until several hours after exposure. Survivors may develop life-
threatening kidney failure.
The acute lethal dose of naphthalene is estimated at 5-15 grams, but some susceptible individuals have died
following ingestion of only 2 grams total. Some people (especially Asians, Arabs, Latin Caucasians and
American and African blacks) may be particularly susceptible, especially males.
Considered an unlikely route of entry in commercial/industrial environments. The liquid may produce
gastrointestinal discomfort and may be harmful if swallowed. Ingestion may result in nausea, pain and
vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.
■ There is some evidence to suggest that this material can cause eye irritation and damage in some persons.
Long term exposure to naphthalene has produced clouding of the lens (cataracts) in workers.
Direct eye contact with petroleum hydrocarbons can be painful, and the corneal epithelium may be temporarily
damaged. Aromatic species can cause irritation and excessive tear secretion.

■ Repeated exposure may cause skin cracking, flaking or drying following normal handling and use.
Skin contact with the material may damage the health of the individual; systemic effects may result following
There is some evidence to suggest that this material can cause inflammation of the skin on contact in some
Workers sensitised to naphthalene and related compounds show an inflammation of the skin with scaling and
reddening. Some individuals show an allergic reaction. Generally, absorption through the skin does not cause
acute systemic reactions except in new-born babies. Photosensitisation, sunburn-like responses or blisters
have been reported. Animal testing revealed naphthalene can cause disease changes in a range of organs.
Open cuts, abraded or irritated skin should not be exposed to this material.
The material may accentuate any pre-existing dermatitis condition.
Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury
with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage
is suitably protected.
Aromatic hydrocarbons may produce sensitivity and redness of the skin. They are not likely to be absorbed
into the body through the skin but branched species are more likely to.
■ Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by sleepiness, reduced
alertness, loss of reflexes, lack of co-ordination, and vertigo.
There is some evidence to suggest that the material can cause respiratory irritation in some persons. The
body's response to such irritation can cause further lung damage.
The acute toxicity of inhaled alkylbenzenes is best described by central nervous system depression. As a rule,
these compounds may also act as general anaesthetics.
Systemic poisoning produced by general anaesthesia is characterised by lightheadedness, nervousness,
apprehension, euphoria, confusion, dizziness, drowsiness, tinnitus, blurred or double vision, vomiting and
sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness and respiratory
depression and arrest. Cardiac arrest may result from cardiovascular collapse. Bradycardia, and hypotension
may also be produced.
Inhaled alkylbenzene vapours cause death in animals at air levels that are relatively similar (typically
LC50s are in the range 5000 -8000 ppm for 4 to 8 hour exposures). It is likely that acute inhalation exposure
to alkylbenzenes resembles that to general anaesthetics.
Alkylbenzenes are not generally toxic other than at high levels of exposure. This may be because their
metabolites have a low order of toxicity and are easily excreted. There is little or no evidence to suggest
that metabolic pathways can become saturated leading to spillover to alternate pathways. Nor is there
evidence that toxic reactive intermediates, which may produce subsequent toxic or mutagenic effects, are
Inhalation hazard is increased at higher temperatures.
Inhaling high concentrations of mixed hydrocarbons can cause narcosis, with nausea, vomiting and
lightheadedness. Low molecular weight (C2-C12) hydrocarbons can irritate mucous membranes and cause
incoordination, giddiness, nausea, vertigo, confusion, headache, appetite loss, drowsiness, tremors and
stupor. Massive exposures can lead to severe central nervous system depression, deep coma and death.
Convulsions can occur due to brain irritation and/or lack of oxygen. Permanent scarring may occur, with
epileptic seizures and brain bleeds occurring months after exposure. Respiratory system effects include
inflammation of the lungs with oedema and bleeding. Lighter species mainly cause kidney and nerve damage; the
heavier paraffins and olefins are especially irritant to the respiratory system. Alkenes produce pulmonary
oedema at high concentrations. Liquid paraffins may produce sensation loss and depressant actions leading to
weakness, dizziness, slow and shallow respiration, unconsciousness, convulsions and death. C5-7 paraffins may
also produce multiple nerve damage. Aromatic hydrocarbons accumulate in lipid rich tissues (typically the
brain, spinal cord and peripheral nerves) and may produce functional impairment manifested by nonspecific
symptoms such as nausea, weakness, fatigue, vertigo; severe exposures may produce inebriation or
unconsciousness. Many of the petroleum hydrocarbons can sensitise the heart and may cause ventricular
fibrillation, leading to death.
Central nervous system (CNS) depression may include general discomfort, symptoms of giddiness, headache,
dizziness, nausea, anaesthetic effects, slowed reaction time, slurred speech and may progress to
unconsciousness. Serious poisonings may result in respiratory depression and may be fatal.
Inhalation of naphthalene vapour is linked with headache, loss of appetite, nausea, damage to the eyes and
kidneys. According to animal testing, long term exposure may cause excessive weakness and increased

salivation, weight loss,difficulty breathing, collapse, and evidence of damage to the skin, liver and lungs.
Inhalation of high concentrations of gas/vapour causes lung irritation with coughing and nausea, centralnervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination.
Inhalation of aerosols (mists, fumes), generated by the material during the course of normal handling, may bedamaging to the health of the individual.
■ There has been concern that this material can cause cancer or mutations, but there is not enough data to
make an assessment.
Prolonged or repeated skin contact may cause drying with cracking, irritation and possible dermatitis
Substance accumulation, in the human body, may occur and may cause some concern following repeated or long-
term occupational exposure.
Constant or exposure over long periods to mixed hydrocarbons may produce stupor with dizziness, weakness and
visual disturbance, weight loss and anaemia, and reduced liver and kidney function. Skin exposure may result
in drying and cracking and redness of the skin. Chronic exposure to lighter hydrocarbons can cause nerve
damage, peripheral neuropathy, bone marrow dysfunction and psychiatric disorders as well as damage the liver
and kidneys.
Animal testing indicates that inhalation of naphthalene may increase the incidence of respiratory tumours and
may aggravate chronic inflammation.
Repeated application of mildly hydrotreated oils (principally paraffinic), to mouse skin, induced skin
tumours; no tumours were induced with severely hydrotreated oils.
Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes.

NULON INJECTOR CLEANER:■ For trimethylbenzenes:Absorption of 1,2,4-trimethylbenzene occurs after oral, inhalation, or dermal exposure. Occupationally,inhalation and dermal exposures are the most important routes of absorption although systemic intoxicationfrom dermal absorption is not likely to occur due to the dermal irritation caused by the chemical promptingquick removal. Following oral administration of the chemical to rats, 62.6% of the dose was recovered asurinary metabolites indicating substantial absorption . 1,2,4-Trimethylbenzene is lipophilic and mayaccumulate in fat and fatty tissues. In the blood stream, approximately 85% of the chemical is bound to redblood cells Metabolism occurs by side-chain oxidation to form alcohols and carboxylic acids which are then conjugated with glucuronic acid, glycine, or sulfates for urinary excretion . After a single oral dose torats of 1200 mg/kg, urinary metabolites consisted of approximately 43.2% glycine, 6.6% glucuronic, and 12.9%sulfuric acid conjugates . The two principle metabolites excreted by rabbits after oral administration of 438mg/kg/day for 5 days were 2,4-dimethylbenzoic acid and 3,4-dimethylhippuric acid . The major routes ofexcretion of 1,2,4-trimethyl- benzene are exhalation of parent compound and elimination of urinarymetabolites. Half-times for urinary metabolites were reported as 9.5 hours for glycine, 22.9 hours forglucuronide, and 37.6 hours for sulfuric acid conjugates.
Acute Toxicity Direct contact with liquid 1,2,4-trimethylbenzene is irritating to the skin and breathing thevapor is irritating to the respiratory tract causing pneumonitis. Breathing high concentrations of thechemical vapor causes headache, fatigue, and drowsiness. In humans liquid 1,2,4-trimethylbenzene isirritating to the skin and inhalation of vapor causes chemical pneumonitis . High concentrations of vapor(5000-9000 ppm) cause headache, fatigue, and drowsiness . The concentration of 5000 ppm is roughly equivalentto a total of 221 mg/kg assuming a 30 minute exposure period (see end note 1). 2.

Painters that worked for several years with a solvent containing 50% 1,2,4- and 30% 1,3,5-trimethylbenzene showed nervousness, tension and anxiety, asthmatic bronchitis, anemia,and alterations in blood clotting; haematological effects may have been due to trace amounts of benzeneRats given 1,2,4-trimethylbenzene orally at doses of 0.5 or 2.0 g/kg/day, 5 days/week for 4 weeks. All rats exposed to the high dose died and 1 rat in the low dose died (no times given); no other effects werereported. Rats exposed by inhalation to 1700 ppm of a trimethylbenzene isomeric mixture for 4 months haddecreased weight gain, lymphopenia and neutrophilia .
Genotoxicity: Results of mutagenicity testing, indicate that the C9 fraction does not induce gene mutationsin prokaryotes (Salmonella tymphimurium/mammalian microsome assay); or in mammalian cells in culture (inChinese hamster ovary cells with and without activation). The C9 fraction does not does not induce chromosomemutations in Chinese hamster ovary cells with and without activation; does not induce chromosome aberrationsin the bone marrow of Sprague-Dawley rats exposed by inhalation (6 hours/day for 5 days); and does not inducesister chromatid exchange in Chinese hamster ovary cells with and without activation.
Developmental/Reproductive Toxicity: A three-generation reproductive study on the C9 fraction was conductedCD rats (30/sex/group) were exposed by inhalation to the C9 fraction at concentrations of 0, 100, 500, or1500 ppm (0, 100, 500, or 1500 mg/kg/day) for 6 hours/day, 5 days/week. There was evidence of parental andreproductive toxicity at all dose levels. Indicators of parental toxicity included reduced body weights,increased salivation, hunched posture, aggressive behavior, and death. Indicators of adverse reproductivesystem effects included reduced litter size and reduced pup body weight. The LOEL was 100 ppm; a no-observed-effect level was not established Developmental toxicity, including possible develop- mental neurotoxicity,was evident in rats in a 3-generation reproductive studyNo effects on fecundity or fertility occurred in rats treated dermally with up to 0.3 mL/rat/day of a mixtureof trimethyl- benzenes, 4-6 hours/day, 5 days/week over one generation.

DISTILLATES, PETROLEUM, MIDDLE, SWEETENED:■ for gas oils and distillate fuels:The gas oils category includes both finished products (distillate fuels) and the refinery streams (gas oils)from which they are blended. The materials in this category, together with those in the Jet Fuel/Kerosenecategory, constitute a generic class of petroleum substances commonly known as middle distillates. Thedistillate fuels covered in this category are used in diesel engines and for both industrial and domesticheating. While within the refinery the gas oil streams exist primarily as intermediates in closed systems.
Selected gas oil streams may ultimately be blended into distillate fuels, marine bunker fuels andoccasionally into lubricants. At ambient temperatures, all the substances in this category are liquids. Gasoil streams and distillate fuels are complex petroleum mixtures, composed primarily of saturated (paraffinicand naphthenic) or aromatic hydrocarbons with carbon numbers ranging from C9 to C30.
Gas Oils are similar from both a process and physical-chemical perspective, being differentiated from eachother primarily by their aromatic and saturated hydrocarbon content. The compositions of the gas oil streamsrange from those that are predominantly saturated hydrocarbons to those that are predominantly aromatichydrocarbons. Consequently, the category can be considered a continuum, bounded by materials that arecompositionally either high in saturated hydrocarbons or aromatic hydrocarbons. While the ratio of thesaturated and aromatic hydrocarbons may vary between category members the saturated and aromatic hydrocarbonsspecies that make up the category members are similar. Based on the available data, the physical-chemicalproperties of an individual category member depend on its compositional makeup, vis a vis saturated andaromatic hydrocarbons. Therefore, gas oil streams that are predominantly saturated hydrocarbons will havesimilar physical-chemical properties, while those that are composed predominantly of aromatic hydrocarbonswill have somewhat different properties. As products that are blended from the gas oil streams, thecompositions of the distillate fuels fall within the range of the compositions shown by the gas oil streamsand reflect the characteristics of the gas oils streams from which they are blended.
Boiling Point Gas oils do not have a single numerical value for boiling point, but rather a boiling or distillation range that reflects the individual components in the hydrocarbon mixture. Distillation rangesfor a variety of gas oils have been reported for a number of blended gas oil products production streams . Typical distillation ranges for blended fuels are 160 to 390 C for an automotive gas oil(diesel fuel), 160 to 400 C for a heating oil, and 170 to 420 C for a distillate marine fuel Typical low endand high end distillation temperatures for gas oil production streams were 172 and 344 C for ahydrodesulfurised middle distillate (65.6% -79.4% saturated hydrocarbons), 185 and 391 C for a straight-runmiddle distillate (78.8 saturated hydrocarbons), and 185 and 372 C for a light catalytic cracked distillate (60.8% -79.8% aromatic hydrocarbons). No substantial differences in boiling range were apparent for gas oilswith high concentrations of either aromatic or saturated hydrocarbonsVapor Pressure : For mixtures such as petroleum products, the vapor pressure of the mixture is the sum of thepartial pressures of the individual components (Dalton's Law of Partial Pressures). Gas oils are expected tohave low vapor pressure due to their boiling range (150 to 450 C) and molecular weights of the constituenthydrocarbons (C9 – 30 carbon atoms). Because the physical-chemical characteristics of distillate fuelsreflect the gas oil streams from which they were produced, these vapor pressure measurements are expected toapproximate the vapor pressures of individual gas oils. Vapour pressure estimates of low molecular weighthydrocarbons of varying isomeric structures fell within a range of 0.01-1.6 kPa, with higher molecular weighthydrocarbons showing very low vapour pressures (e.g., 10-8 to 10-10 kPa).
Partition Coefficient The percent distribution of the hydrocarbon groups (i.e., paraffins, olefins, naphthenes, and aromatics) and the carbon chain lengths of hydrocarbon constituents in gas oils largelydetermines the partitioning characteristics of the mixture. Generally, hydrocarbon chains with fewer carbonatoms tend to have lower partition coefficients than those with higher carbon numbers complex mixtures, it is not possible to determine their log Kow values. Rather, partition coefficients havebeen calculated for individual component hydrocarbons from known hydrocarbon composition Kow values ranged from 3.9 to >6.0 for a hydrodesulfurised middle distillate ((65.6% -79.4% saturatedhydrocarbons), straight-run middle distillate (78.8% saturated hydrocarbons), and a light cat-crackeddistillate (60.8% -79.8% aromatic hydrocarbons). There are no apparent differences in the range of Kow valuesdetermined for gas oils with high concentrations of either aromatic or saturated hydrocarbons. A similarrange of partition coefficients would be expected for component hydrocarbons in distillate fuels.

light energy to result in a structural transformation. Only light energy at wavelengths between 290 and 750nm can result in photochemical transformations in the environment, although absorption is not alwayssufficient for a chemical to undergo photochemical degradation. Saturated and one-ring aromatic hydrocarbonsdo not show absorbance in the 290 to 800 nm range and would not be expected to be directly photodegraded.
Polyaromatic hydrocarbons, on the other hand, have shown absorbance of the 290 to 800 nm range of lightenergy and could potentially undergo photolysis reactions. The degree and rate at which these compoundsphotodegrade depends upon whether conditions allow penetration of light with sufficient energy to effect achange.
Components in gas oils that do not directly photodegrade (e.g., paraffins, naphthenes, and one-ring aromaticcompounds) may be subject to indirect photodegradation. Indirect photodegradation is the reaction withphotosensitised oxygen in the atmosphere in the form of hydroxyl radicals (OH ).
Atmospheric oxidation rates and half-lives were calculated for the low and high end of the range of molecularweight constituents of gas oils (e.g., C9 and 30 hydrocarbon structures). Half-life estimates for thesecompounds ranged from 0.1 (for various C9 to C30 olefinic structures and C30 2+ring aromatic compounds) to1.5 days (for a C9 one-ring aromatic structure). Based on the calculated half-life values calculatedsubstantial differences in indirect photodegradation potential is expected between gas oils with highconcentrations of either aromatic or saturated hydrocarbons. A similar range of water solubility values wouldbe expected for component hydrocarbons in distillate fuels.
Water Solubility : When released to water, gas oils will float and spread at a rate that is viscosity-dependent. Component hydrocarbons in gas oils will partition to water according to their individualsolubility values. For individual hydrocarbon constituents in gas oils, water solubility values vary byorders of magnitude. Molecular weight and chemical structure have a great influence on the ultimate degree ofsolubility. Calculated water solubility ranged from essentially insoluble (approximately 10-8 mg/L) for thehigher molecular weight fractions (e.g., C30) within gas oil to approximately 52 mg/L for a C9 alkylbenzene.
Hydrolysis: The materials in the gas oils category do not contain chemical moieties that undergo hydrolysis.
Transport and Distribution in the Environment (Fugacity) Models have been used to estimate the percentdistribution in environmental media (i.e., air, water, soil, sediment, and fish) of various C9 to C30compounds representing the different classes of hydrocarbons found in gas oils (e.g., paraffins, olefins,naphthenes, and aromatics). Hydrocarbons having nine carbon atoms showed a tendency to partition to air (upto 98%). As molecular weight increases, partitioning shifts to soil, which accounts for 98% of thedistribution of the C30 components. This trend was similar for saturate and aromatic structures alike.
Therefore, gas oils with high concentrations of either aromatic or saturated hydrocarbons are expected topartition in the environment in a similar mannerBiodegradation : Much of what is known is based on information gained from testing hydrocarbon mixtures ofother petroleum products. Under standard biodegradability tests, hydrocarbon compounds representative ofthose found in gas oils typically do not pass ready biodegradability test conditions. Although thosecompounds are not recognized as being readily biodegradable, most hydrocarbon species present in gas oils areknown to be ultimately degraded by aerobic microorganisms Lower molecular weight compounds may be expected to be degraded relatively quickly in aerobic conditions, while higher molecular weight compounds,particularly polycyclic aromatics, will degrade slower. Much of this evidence is based on bioremediationstudies of contaminated soils, which have shown that hydrocarbon components in gas oils are degraded in thepresence of oxygen. Bioremediation of a diesel fuel spill has also been demonstrated under Arctic conditionsUnder anaerobic conditions, such as anoxic sediments, rates of biodegradation of gas oils components arenegligible and the gas oils may persist under those conditions for some time. Degradation then will bedependent on bioturbation or resuspension to provide microbes with access to oxygen.
Ecotoxicity: Multiple ecotoxicological studies on heating and transportation fuels (e.g., no. 2 fuel oil and diesel fuel) have been conducted. In general, these commercial distillate fuels show moderate toxicity to aquatic life.
LC50 values for fish ranged from 3.2 to 65 mg/L , while EC50 values for invertebrates ranged from 2.0 to 210mg/L.

Naphthalene released to the atmosphere may be transported to surface water and/or soil by wet or drydeposition. Since most airborne naphthalene is in the vapor phase, deposition is expected to be very slow(about 0.04–0.06 cm/sec). It has been estimated that about 2–3% of naphthalene emitted to air is transportedto other environmental media, mostly by dry deposition .
Naphthalene in surface water may volatilise to the atmosphere. The rate of volatilization also depends uponseveral environmental conditions, including temperature, wind velocity, and mixing rates of the air and watercolumns.
Log octanol/water partition coefficients (Kow) for naphthalene range from 3.29 to 3.37 and log organic carboncoefficients (Koc) range from 2.97 to 3.27. The reported experimentally determined log Koc is 3.11. Based onthe magnitude of these values, it is expected that only a small fraction (<10%) of naphthalene in typicalsurface water would be associated with particulate matter. Thus, naphthalene discharged to surface waterswould remain largely in solution, with smaller quantities being associated with suspended solids and benthicsediments.
Naphthalene is easily volatilized from aerated soils and is adsorbed to a moderate extent (10%) . The extentof sorption depends on the organic carbon content of the soil, with rapid movement expected through sandysoils. The estimated soil adsorption coefficient for naphthalene in a soil with <0.6% organic carbon is 1.8 .
Because it adsorbs to aquifer material, naphthalene's passage through groundwater will be somewhat retarded.
However, sorption of naphthalene to aquifer materials with low organic carbon content (<0.03%) may beenhanced by the presence of nonionic low-polarity organics, such as tetrachloroethene, commonly found athazardous waste sites. Bioconcentration factors (BCFs) for naphthalene have been measured and calculated fromthe Kow, Koc, or water solubility. The values reported for log BCF range from 1.6 to 3, indicating moderatebioconcentration in aquatic organisms. Naphthalene is reported to be rapidly eliminated from invertebrateswhen the organisms are placed in pollutant-free water, and naphthalene is readily metabolized in fish . Basedon the magnitude of the Kow, bioaccumulation in the food chain is not expected to occur. However, naphthaleneexposure of cows and chickens could lead to the presence of naphthalene in milk and eggs.
Limited data were located on transport and partitioning of methylnaphthalenes in the environment. Therespective vapor pressures (0.054 and 0.068 mmHg), water solubilities (25.8 and 24.6 mg/L), and Henry's lawconstants (3.60x10-4 and 4.99x10-4 atm-m3/mol) for 1-methylnaphthalene and 2-methylnaphthalene are of similarmagnitude to these properties for naphthalene. Thus, it is likely that loss of methylnaphthalenes fromambient water occurs by volatilization. Based on the magnitude of log Kow for 1-methylnaphthalene and 2-methylnaphthalene (3.87 and 3.86, respectively) and the experimental log Koc for 2-methylnaphthalene (3.93) these chemicals may partition similarly to naphthalene in environmental media and are expected to be slightlymobile to immobile in soils. Log BCFs calculated for 2-methylnaphthalene range from 2 to 2.8 and measured logBCFs for 1-methylnaphthalene and 2-methylnaphthalene in oysters ranged from 2.7 to 4.1. Methylnaphthalenesare also metabolised and excreted rapidly by fish and shellfish when they are removed from polluted waters.
The most important atmospheric removal process for naphthalene is reaction with photochemicallyproduced hydroxyl radicals. The major products of this reaction are 1- and 2-naphthol and 1- and 2-nitronaphthalene. Naphthalene also reacts with N2O5, nitrate radicals, and ozone in the atmosphere andphotolysis is expected to occur. Methylnaphthalenes also react with hydroxyl radicals. The reported rateconstants are 5.30x10-11 and 5.23x10-11 cm3/molecule-sec for 1-methylnaphthalene and 2-methylnaphthalene,respectively. Based on an atmospheric hydroxyl radical concentration of 1x10 6/cm3, the correspondingatmospheric half-lives are 3.6 and 3.7 hours. Reactions of 1-methylnaphthalene and 2-methylnaphthalene withN2O5 radicals have half-lives of 24 and 19 days, respectively. These chemicals also react with atmosphericozone.
Naphthalene and methylnaphthalenes are degraded in water by photolysis and biological processes. The half-life for photolysis of naphthalene in surface water is estimated to be about 71 hours, but the half-life indeeper water (5 m) is estimated at 550 days. The half-lives for photolysis of 1-methylnaphthalene and 2-methylnaphthalene were estimated at 22 and 54 hours, respectively.
Biodegradation of naphthalene is sufficiently rapid for it to be a dominant fate process in aquatic systems.
Data on biodegradation of naphthalene in biodegradability tests and natural systems suggest thatbiodegradation occurs after a relatively short period of acclimation. Methylnaphthalenes are biodegradedunder aerobic conditions after adaptation. The highest degradation rates were reported in water constantlypolluted with petroleum.
Naphthalene biodegradation rates are about 8–20 times higher in sediment than in the water column above thesediment. Methylnaphthalenes biodegrade more slowly. Reported half-lives in sediments were 46 weeks for 1-methylnaphthalene and ranged from 14 to 50 weeks for 2-methylnaphthalene.
In soils, biodegradation potential is important to biological remediation of soil. Studies on biodegradationof PAHs suggest that adsorption to the organic matter significantly reduces the bioavailability formicroorganisms, and thus the biodegradability, of PAHs, including naphthalene. Biodegradation is accomplished continued.

through the action of aerobic microorganisms and declines precipitously when soil conditions becomeanaerobic. Studies indicate that naphthalene biodegrades to carbon dioxide in aerobic soils, with salicylateas an intermediate product. Abiotic degradation of naphthalene seldom occurs in soils. The behavior of 1-methylnaphthalene in sandy loam was very similar to that of naphthalene. 1-Methylnaphthalene was easilyvolatilised from aerated soil, and the biodegradation half-life averaged between Ecotoxicity:Acute toxicity data on naphthalene are available for several fish species (freshwater and marine). If lowreliable data (too old, static test, nominal concentrations) are excluded, 96h LC50 values range from 1.8 to7.8 mg/L. Comparable results were obtained with other vertebrates (amphibians).
From chronic toxicity tests, a precise NOEL is not clearly determined. A NOEC of 0.12 mg/L was observed in a40 days test on juvenile pink salmon, but 50% mortality at 0.11 mg/L was calculated for trout fry exposedduring hatching.
Several data are also available for invertebrates, showing 48h EC50 values ranging from 2.1 to 24 mg/L. Alsoin this case, higher figures must be taken with care due to nominal concentrations.
Chronic data on freshwater invertebrates are methodologically unclear or questionable.
On algae too, data available are obtained with hardly comparable methodological approaches. 50%photosynthesis reduction was observed at 2.8 mg/L in 4 hours experiments.
QSAR predictions using equations for narcosis give results consistent with experimental short-term data onfish daphnia and algae.
