Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS
naphtha petroleum, light aliphatic solvent Section 4 - FIRST AID MEASURES
SWALLOWED
• If spontaneous vomiting appears imminent or occurs, hold patient's head down, lower than their hips to help
avoid possible aspiration of vomitus.
• 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
unconscious.
• 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.
EYE
■ 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.
• If pain persists or recurs seek medical attention.
• Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.
SKIN
■ If skin or hair contact occurs:
• Flush skin and hair with running water (and soap if available).
• Seek medical attention in event of irritation.
INHALED
• If fumes or combustion products are inhaled remove from contaminated area.
• Other measures are usually unnecessary.
NOTES TO PHYSICIAN
■ 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
continued.

occurred after ingestion, the patient should be monitored for difficult breathing, as adverse effects ofaspiration into the lungs may be delayed up to 48 hours.
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 poorarterial 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 inobviously symptomatic patients. The lungs excrete inhaled solvents, so that hyperventilation improvesclearance.
• 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 thepreferred 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].

ARDEX WPM 657 GENERAL PURPOSE SEALANT:
■ Because the margin of safety of the quartz TLV is not known with certainty and given the associated link between silicosis and lung cancer it is recommended that quartz concentrations be maintained as far below theTLV as prudent practices will allow.
NAPHTHA PETROLEUM, LIGHT ALIPHATIC SOLVENT: ■ 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 continued.

Odour threshold: 0.25 ppm.
The TLV-TWA is protective against ocular and upper respiratory tract irritation and is recommended for bulk handling of gasoline based on calculations of hydrocarbon content of gasoline vapour. A STEL isrecommended to prevent mucous membrane and ocular irritation and prevention of acute depression of thecentral nervous system. Because of the wide variation in molecular weights of its components, the conversionof ppm to mg/m3 is approximate. Sweden recommends hexane type limits of 100 ppm and heptane and octane typelimits of 300 ppm. Germany does not assign a value because of the widely differing compositions and resultantdifferences in toxic properties.
Odour Safety Factor (OSF)OSF=0.042 (gasoline).
for petroleum distillates:CEL TWA: 500 ppm, 2000 mg/m3 (compare OSHA TWA).
REL TWA: 370 ppm ■ The concentration of dust, for application of respirable dust limits, is to be determined from the fraction that penetrates a separator whose size collection efficiency is described by a cumulative log-normalfunction with a median aerodynamic diameter of 4.0 µm (+-) 0.3 µm and with a geometric standard deviation of1.5 µm (+-) 0.1 µm, i.e.generally less than 5 µm.
Because the margin of safety of the quartz TLV is not known with certainty and given the associated link between silicosis and lung cancer it is recommended that quartz concentrations be maintained as far below theTLV as prudent practices will allow.
PERSONAL PROTECTION
EYE
• 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 eachworkplace or task. This should include a review of lens absorption and adsorption for the class ofchemicals in use and an account of injury experience. Medical and first-aid personnel should be trained intheir removal and suitable equipment should be readily available. In the event of chemical exposure, begineye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at thefirst signs of eye redness or irritation - lens should be removed in a clean environment only after workershave washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59].
HANDS/FEET
■ Suitability and durability of glove type is dependent on usage. Factors such as:
• frequency and duration of contact,
• chemical resistance of glove material,
• glove thickness and
• dexterity,
are important in the selection of gloves.
• Wear chemical protective gloves, eg. PVC.
• Wear safety footwear or safety gumboots, eg. Rubber.
OTHER
• Overalls.
• PVC Apron.
• PVC protective suit may be required if exposure severe.
• Eyewash unit.
• Ensure there is ready access to a safety shower.
• Some plastic personal protective equipment (PPE) (e.g. gloves, aprons, overshoes) are not recommended as
they may produce static electricity.
• For large scale or continuous use wear tight-weave non-static clothing (no metallic fasteners, cuffs or pockets), non sparking safety footwear.

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
■ Swallowing of the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis; serious
consequences may result. (ICSC13733).
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.
EYE
■ There is some evidence to suggest that this material can cause eye irritation and damage in some persons.
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.
SKIN
■ The liquid may be miscible with fats or oils and may degrease the skin, producing a skin reaction described
as non-allergic contact dermatitis. The material is unlikely to produce an irritant dermatitis as described
in EC Directives .
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.
INHALED
■ 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.
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.
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.
CHRONIC HEALTH EFFECTS
■ Based on experience with animal studies, exposure to the material may result in toxic effects to the
development of the foetus, at levels which do not cause significant toxic effects to the mother.

Section 11 - TOXICOLOGICAL INFORMATION
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 andvisual disturbance, weight loss and anaemia, and reduced liver and kidney function. Skin exposure may resultin drying and cracking and redness of the skin. Chronic exposure to lighter hydrocarbons can cause nervedamage, peripheral neuropathy, bone marrow dysfunction and psychiatric disorders as well as damage the liverand kidneys.
Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes.

TOXICITY AND IRRITATION
■ Not available. Refer to individual constituents.
NAPHTHA PETROLEUM, LIGHT ALIPHATIC SOLVENT:■ unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
■ Lifetime exposure of rodents to gasoline produces carcinogenicity although the relevance to humans has beenquestioned. Gasoline induces kidney cancer in male rats as a consequence of accumulation of the alpha2-microglobulin protein in hyaline droplets in the male (but not female) rat kidney. Such abnormal accumulationrepresents lysosomal overload and leads to chronic renal tubular cell degeneration, accumulation of celldebris, mineralisation of renal medullary tubules and necrosis. A sustained regenerative proliferation occursin epithelial cells with subsequent neoplastic transformation with continued exposure. The alpha2-microglobulin is produced under the influence of hormonal controls in male rats but not in females and, moreimportantly, not in humans.

■ DO NOT discharge into sewer or waterways.
Refer to data for ingredients, which follows: ARDEX WPM 657 GENERAL PURPOSE SEALANT:Marine Pollutant: NAPHTHA PETROLEUM, LIGHT ALIPHATIC SOLVENT:■ For hydrocarbons:Environmental fate:The lower molecular weight hydrocarbons are expected to form a "slick" on the surface of waters after releasein calm sea conditions. This is expected to evaporate and enter the atmosphere where it will be degradedthrough reaction with hydroxy radicals.
Some hydrocarbon will become associated with benthic sediments, and it is likely to be spread over a fairlywide area of sea floor. Marine sediments may be either aerobic or anaerobic. The material, in probability, isbiodegradable, under aerobic conditions (isomerised olefins and alkenes show variable results). Evidence alsosuggests that the hydrocarbons may be degradable under anaerobic conditions although such degradation inbenthic sediments may be a relatively slow process.
Under aerobic conditions hydrocarbons degrade to water and carbon dioxide, while under anaerobic processesthey produce water, methane and carbon dioxide.
Alkenes have low log octanol/water partition coefficients (Kow) of about 1 and estimated bioconcentrationfactors (BCF) of about 10; aromatics have intermediate values (log Kow values of 2-3 and BCF values of 20-200), while C5 and greater alkanes have fairly high values (log Kow values of about 3-4.5 and BCF values of100-1,500The estimated volatilisation half-lives for alkanes and benzene, toluene, ethylbenzene, xylene (BTEX)components were predicted as 7 days in ponds, 1.5 days in rivers, and 6 days in lakes. The volatilisationrate of naphthalene and its substituted derivatives were estimated to be slowerIndigenous microbes found in many natural settings (e.g., soils, groundwater, ponds) have been shown to becapable of degrading organic compounds. Unlike other fate processes that disperse contaminants in theenvironment, biodegradation can eliminate the contaminants without transferring them across media.
The final products of microbial degradation are carbon dioxide, water, and microbial biomass. The rate ofhydrocarbon degradation depends on the chemical composition of the product released to the environment aswell as site-specific environmental factors. Generally the straight chain hydrocarbons and the aromatics aredegraded more readily than the highly branched aliphatic compounds. The n-alkanes, n-alkyl aromatics, and thearomatics in the C10-C22 range are the most readily biodegradable; n-alkanes, n-alkyl aromatics, andaromatics in the C5-C9 range are biodegradable at low concentrations by some microorganisms, but aregenerally preferentially removed by volatilisation and thus are unavailable in most environments; n-alkanesin the C1-C4 ranges are biodegradable only by a narrow range of specialised hydrocarbon degraders; and n-alkanes, n-alkyl aromatics, and aromatics above C22 are generally not available to degrading microorganisms.
Hydrocarbons with condensed ring structures, such as PAHs with four or more rings, have been shown to berelatively resistant to biodegradation. PAHs with only 2 or 3 rings (e.g., naphthalene, anthracene) are moreeasily biodegraded. In almost all cases, the presence of oxygen is essential for effective biodegradation ofoil. The ideal pH range to promote biodegradation is close to neutral (6-8). For most species, the optimal pHis slightly alkaline, that is, greater than 7.
All biological transformations are affected by temperature. Generally, as the temperature increases,biological activity tends to increase up to a temperature where enzyme denaturation occurs.
Atmospheric fate: Alkanes, isoalkanes, and cycloalkanes have half-lives on the order of 1-10 days, whereasalkenes, cycloalkenes, and substituted benzenes have half-lives of 1 day or less. Photochemical oxidationproducts include aldehydes, hydroxy compounds, nitro compounds, and peroxyacyl nitrates. Alkenes, certainsubstituted aromatics, and naphthalene are potentially susceptible to direct photolysis.
Ecotoxicity:Based on test results, as well as theoretical considerations, the potential for bioaccumulation may be high.

Section 12 - ECOLOGICAL INFORMATION
Toxic effects are often observed in species such as blue mussel, daphnia, freshwater green algae, marinecopepods and amphipods.
The values of log Kow for individual hydrocarbons increase with increasing carbon number within homologousseries of generic types. Quantitative structure activity relationships (QSAR), relating log Kow values ofsingle hydrocarbons to toxicity, show that water solubility decreases more rapidly with increasing Kow thandoes the concentration causing effects. This relationship varies somewhat with species of hydrocarbon, but itfollows that there is a log Kow limit for hydrocarbons, above which, they will not exhibit acute toxicity;this limit is at a log Kow value of about 4 to 5. It has been confirmed experimentally that for fish andinvertebrates, paraffinic hydrocarbons with a carbon number of 10 or higher (log Kow >5) show no acutetoxicity and that alkylbenzenes with a carbon number of 14 or greater (log Kow >5) similarly show no acutetoxicity. QSAR equations for chronic toxicity also suggest that there should be a point where hydrocarbonswith high log Kow values become so insoluble in water that they will not cause chronic toxicity, that is,that there is also a solubility cut-off for chronic toxicity. Thus, paraffinic hydrocarbons with carbonnumbers of greater than 14 (log Kow >7.3) should show no measurable chronic toxicity.
■ Drinking Water Standards: hydrocarbon total: 10 ug/l (UK max.).
■ For petroleum derivatives:Chemical analysis for all individual compounds in a petroleum bulk product released to the environment isgenerally unrealistic due to the complexity of these mixtures and the laboratory expense. Determining thechemical composition of a petroleum release is further complicated by hydrodynamic, abiotic, and bioticprocesses that act on the release to change the chemical character.
The longer the release is exposed to the environment, the greater the change in chemical character and theharder it is to obtain accurate analytical results reflecting the identity of the release. After extensiveweathering, detailed knowledge of the original bulk product is often less valuable than current site-specificinformation on a more focused set of hydrocarbon components. Health assessment efforts are frequentlyfrustrated by three primary problems: (1) the inability to identify and quantify the individual compoundsreleased to the environment as a consequence of a petroleum spill; (2) the lack of information characterizingthe fate of the individual compounds in petroleum mixtures; and (3) the lack of specific health guidancevalues for the majority of chemicals present in petroleum products. To define the public health implicationsassociated with exposure to petroleum hydrocarbons, it is necessary to have a basic understanding ofpetroleum properties, compositions, and the physical, chemical, biological, and toxicological properties ofthe compounds most often identified as the key chemicals of concern.
Environmental fate:Petroleum products released to the environment migrate through soil via two general pathways: (1) as bulk oilflow infiltrating the soil under the forces of gravity and capillary action, and (2) as individual compoundsseparating from the bulk petroleum mixture and dissolving in air or water. When bulk oil flow occurs, itresults in little or no separation of the individual compounds from the product mixture and the infiltrationrate is usually fast relative to the dissolution rate. Many compounds that are insoluble and immobile inwater are soluble in bulk oil and will migrate along with the bulk oil flow. Factors affecting the rate ofbulk oil infiltration include soil moisture content, vegetation, terrain, climate, rate of release (e.g.,catastrophic versus slow leakage), soil particle size (e.g., sand versus clay), and oil viscosity (e.g.,gasoline versus motor oil).
As bulk oil migrates through the soil column, a small amount of the product mass is retained by soilparticles. The bulk product retained by the soil particles is known as "residual saturation".
Depending upon the persistence of the bulk oil, residual saturation can potentially reside in the soil foryears. Residual saturation is important as it determines the degree of soil contamination and can act as acontinuing source of contamination for individual compounds to separate from the bulk product and migrateindependently in air or groundwater. Residual saturation is important as it determines the degree of soilcontamination and can act as a continuing source of contamination for individual compounds to separate fromthe bulk product and migrate independently in air or groundwater. When the amount of product released to theenvironment is small relative to the volume of available soil, all of the product is converted to residualsaturation and downward migration of the bulk product usually ceases prior to affecting groundwaterresources. Adverse impacts to groundwater may still occur if rain water infiltrates through soil containingresidual saturation and initiates the downward migration of individual compounds. When the amount of productreleased is large relative to the volume of available soil, the downward migration of bulk product ceases aswater-saturated pore spaces are encountered. If the density of the bulk product is less than that of water,the product tends to "float" along the interface between the water saturated and unsaturated zones and spreadhorizontally in a pancake-like layer, usually in the direction of groundwater flow. Almost all motor andheating oils are less dense than water. If the density of the bulk product is greater than that of water, theproduct will continue to migrate downward through the water table aquifer under the continued influence of continued.

gravity. Downward migration ceases when the product is converted to residual saturation or when animpermeable surface is encountered.
As the bulk product migrates through the soil column, individual compounds may separate from the mixture andmigrate independently. Chemical transport properties such as volatility, solubility, and sorption potentialare often used to evaluate and predict which compounds will likely separate from the mixture. Since petroleumproducts are complex mixtures of hundreds of compounds, the compounds characterized by relatively high vaporpressures tend to volatilise and enter the vapor phase. The exact composition of these vapors depends on thecomposition of the original product. Using gasoline as an example, compounds such as butane, propane, benzene,toluene, ethylbenzene and xylene are preferentially volatilised. Because volatility represents transfer ofthe compound from the product or liquid phase to the air phase, it is expected that the concentration of thatcompound in the product or liquid phase will decrease as the concentration in the air phase increases.
In general, compounds having a vapor pressure in excess of 10-2 mm Hg are more likely to be present in theair phase than in the liquid phase. Compounds characterized by vapor pressures less than 10-7 mm Hg are morelikely to be associated with the liquid phase. Compounds possessing vapor pressures that are less than 10-2mm Hg, but greater than 10-7 mm Hg, will have a tendency to exist in both the air and the liquid phases.
Lighter petroleum products such as gasoline contain constituents with higher water solubility and volatilityand lower sorption potential than heavier petroleum products such as fuel oil.
Data compiled from gasoline spills and laboratory studies indicate that these light-fraction hydrocarbonstend to migrate readily through soil, potentially threatening or affecting groundwater supplies. In contrast,petroleum products with heavier molecular weight constituents, such as fuel oil, are generally morepersistent in soils, due to their relatively low water solubility and volatility and high sorption capacity.
Solubility generally decreases with increasing molecular weight of the hydrocarbon compounds. For compoundshaving similar molecular weights, the aromatic hydrocarbons are more water soluble and mobile in water thanthe aliphatic hydrocarbons and branched aliphatics are less water-soluble than straight-chained aliphatics.
Aromatic compounds in petroleum fuels may comprise as much as 50% by weight; aromatic compounds in the C6-C13,range made up approximately 95% of the compounds dissolved in water.
Indigenous microbes found in many natural settings (e.g., soils, groundwater, ponds) have been shown to becapable of degrading organic compounds. Unlike other fate processes that disperse contaminants in theenvironment, biodegradation can eliminate the contaminants without transferring them across media.
The final products of microbial degradation are carbon dioxide, water, and microbial biomass. The rate ofhydrocarbon degradation depends on the chemical composition of the product released to the environment aswell as site-specific environmental factors. Generally the straight chain hydrocarbons and the aromatics aredegraded more readily than the highly branched aliphatic compounds. The n-alkanes, n-alkyl aromatics, and thearomatics in the C10-C22 range are the most readily biodegradable; n-alkanes, n-alkyl aromatics, andaromatics in the C5-C9 range are biodegradable at low concentrations by some microorganisms, but aregenerally preferentially removed by volatilisation and thus are unavailable in most environments; n-alkanesin the C1-C4 ranges are biodegradable only by a narrow range of specialized hydrocarbon degraders; and n-alkanes, n-alkyl aromatics, and aromatics above C22 are generally not available to degrading microorganisms.
Hydrocarbons with condensed ring structures, such as PAHs with four or more rings, have been shown to berelatively resistant to biodegradation. PAHs with only 2 or 3 rings (e.g., naphthalene, anthracene) are moreeasily biodegraded. PAHs with only 2 or 3 rings (e.g., naphthalene, anthracene) are more easily biodegraded.
A large proportion of the water-soluble fraction of the petroleum product may be degraded as the compounds gointo solution. As a result, the remaining product may become enriched in the alicyclics, the highly branchedaliphatics, and PAHs with many fused rings.
In almost all cases, the presence of oxygen is essential for effective biodegradation of oil. Anaerobicdecomposition of petroleum hydrocarbons leads to extremely low rates of degradation. The ideal pH range topromote biodegradation is close to neutral (6-8). For most species, the optimal pH is slightly alkaline, thatis, greater than 7. The moisture content of the contaminated soil will affect biodegradation of oils due todissolution of the residual compounds, dispersive actions, and the need for microbial metabolism to sustainhigh activity. The moisture content in soil affects microbial locomotion, solute diffusion, substrate supply,and the removal of metabolic by-products. Biodegradation rates in soils are also affected by the volume ofproduct released to the environment. At concentrations of 0.5% of oil by volume, the degradation rate in soilis fairly independent of oil concentrations. However, as oil concentration rises, the first order degradationrate decreases and the oil degradation half-life increases. Ultimately, when the oil reaches saturationconditions in the soil (i.e., 30-50% oil), biodegradation virtually ceases.
Excessive moisture will limit the gaseous supply of oxygen for enhanced decomposition of petroleumhydrocarbons. Most studies indicate that optimum moisture content is within 50-70% of the water holdingcapacity.
All biological transformations are affected by temperature. Generally, as the temperature increases, continued.

biological activity tends to increase up to a temperature where enzyme denaturation occurs. The presence ofoil should increase soil temperature, particularly at the surface. The darker color increases the heatcapacity by adsorbing more radiation. The optimal temperature for biodegradation to occur ranges from 18 C to30 C. Minimum rates would be expected at 5 C or lower.
SILICA CRYSTALLINE - QUARTZ:■ For silica:The literature on the fate of silica in the environment concerns dissolved silica in the aquatic environment,irrespective of its origin (man-made or natural), or structure (crystalline or amorphous). Indeed, oncereleased and dissolved into the environment no distinction can be made between the initial forms of silica.
At normal environmental pH, dissolved silica exists exclusively as monosilicic acid [Si(OH)4]. At pH 9.4 thesolubility of amorphous silica is about 120 mg SiO2/l . Quartz has a solubility of only 6 mg/l, but its rateof dissolution is so slow at ordinary temperature and pressure that the solubility of amorphous silicarepresents the upper limit of dissolved silica concentration in natural waters Moreover, silicic acid is thebioavailable form for aquatic organisms and it plays an important role in the biogeochemical cycle of Si,particularly in the oceans.
In the oceans, the transfer of dissolved silica from the marine hydrosphere to the biosphere initiates theglobal biological silicon cycle. Marine organisms such as diatoms, silicoflagellates and radiolarians buildup their skeletons by taking up silicic acid from seawater. After these organisms die, the biogenic silicaaccumulated in them partly dissolves. The portion of the biogenic silica that does not dissolve settles andultimately reaches the sediment. The transformation of opal (amorphous biogenic silica) deposits in sedimentsthrough diagenetic processes allows silica to re-enter the geological cycle. Silica is labile between thewater and sediment interfaceEcotoxicity:Fish LC50 (96 h): Brachydanio rerio >10000 mg/l; zebra fish >10000 mg/lDaphnia magna EC50 (24 h): >1000 mg/l; LC50 924 h): >10000 mg/l.
■ Metal-containing inorganic substances generally have negligible vapour pressure and are not expected topartition to air. Once released to surface waters and moist soils their fate depends on solubility anddissociation in water. Environmental processes (such as oxidation and the presence of acids or bases) maytransform insoluble metals to more soluble ionic forms. Microbiological processes may also transforminsoluble metals to more soluble forms. Such ionic species may bind to dissolved ligands or sorb to solidparticles in aquatic or aqueous media. A significant proportion of dissolved/ sorbed metals will end up insediments through the settling of suspended particles. The remaining metal ions can then be taken up byaquatic organisms.
When released to dry soil most metals will exhibit limited mobility and remain in the upper layer; some willleach locally into ground water and/ or surface water ecosystems when soaked by rain or melt ice.
Environmental processes may also be important in changing solubilities.
Even though many metals show few toxic effects at physiological pHs, transformation may introduce new ormagnified effects.
A metal ion is considered infinitely persistent because it cannot degrade further.
The current state of science does not allow for an unambiguous interpretation of various measures ofbioaccumulation.
The counter-ion may also create heath and environmental concerns once isolated from the metal. Under normalphysiological conditions the counter-ion may be essentially insoluble and may not be bioavailable.
Environmental processes may enhance bioavailability.

Section 13 - DISPOSAL CONSIDERATIONS
■ Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operating in their area. In some areas, certain wastes must be tracked.
A Hierarchy of Controls seems to be common - the user should investigate:• Reduction,• Reuse• Recycling• Disposal (if all else fails)This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. If it has been contaminated, it may be possible to reclaim the product by filtration, distillation or some other means. Shelf life considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and recycling or reuse may not always be appropriate.
• DO NOT allow wash water from cleaning or process equipment to enter drains.
• It may be necessary to collect all wash water for treatment before disposal.
• In all cases disposal to sewer may be subject to local laws and regulations and these should be considered first.
• Where in doubt contact the responsible authority.
• Recycle wherever possible.
• Consult manufacturer for recycling options or consult local or regional waste management authority for disposal if no suitable treatment or disposal facility can be identified.
• Dispose of by: Burial in a licenced land-fill or Incineration in a licenced apparatus (after admixture with suitable combustible material).
• Decontaminate empty containers. Observe all label safeguards until containers are cleaned and destroyed.
