Signs and Symptoms of Acute Carbon Disulfide Exposure: Acute exposure to carbon disulfide primarily affects the central nervous system producing signs and symptoms that may include headache, dizziness, difficulty swallowing, nervousness, tremors, mental depression, delirium, psychosis, convulsions, paralysis, and coma. Nausea, vomiting, cyanosis (blue tint to skin and mucous membranes), hypothermia (low body temperature), and peripheral vascular collapse may also occur. Respiratory effects include coughing, dyspnea (shortness of breath), and respiratory failure. Carbon disulfide is a strong skin irritant; dermal exposure may result in severe burns. Eye exposure may cause degeneration of the retina and optic nerve. Pupils may be dilated.

Emergency Life-Support Procedures: Acute exposure to carbon disulfide may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:

1. Move victims to fresh air. Emergency personnel should avoid self-exposure to carbon disulfide.

2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.

3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.

4. Transport to a health care facility.

Dermal/Eye Exposure:

1. Remove victims from exposure. Emergency personnel should avoid self- exposure to carbon disulfide.

3. Remove contaminated clothing as soon as possible.

4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.

5. Wash exposed skin areas three times. Wash initially with soap and water follow with an alcohol wash, then wash again with soap and water.

6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.

7. Transport to a health care facility.

Ingestion Exposure:

1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.

2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.

3. Give the victims water or milk: Children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should be given only if victims are conscious and alert.

4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.

5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.

6. Transport to a health care facility. (EPA, 1998)

General First Aid:

· Call 911 or emergency medical service.

· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.

· Move victim to fresh air if it can be done safely.

· Administer oxygen if breathing is difficult.

· If victim is not breathing:

-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.

-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).

-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.

· Remove and isolate contaminated clothing and shoes.

· For minor skin contact, avoid spreading material on unaffected skin.

· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.

· For severe burns, immediate medical attention is required.

· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.

If the vapor concentration exceeds 2 percent by volume or is unknown, self-contained breathing mask with full face should be used by all persons entering contaminated area. Wear special protective clothing. Isolate for 1/2 mile in all directions if tank car or truck is involved in fire.

Use dry chemical, carbon dioxide or other inert gas. Cooling and blanketing with water spray is effective in case of fires in metal containers or tanks to help prevent reignition by hot surfaces. Foam is ineffective. (EPA, 1998)

Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

To fight fire, use water, carbon dioxide, dry chemical, fog, mist.

Water and foam may be ineffective on fire.

If material on fire or involved in fire: Do not extinguish the fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide.

Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Immediate precautionary measure

· Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.

· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.

· If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Remove all ignition sources. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quantities, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be reclaimed or collected and atomized in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device. Carbon disulfide should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.

Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Apply appropriate foam to diminish vapor and fire hazard.

Environmental considerations: Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.

Environmental considerations: Air spill: Apply water spray or mist to knock down vapors. Combustion products include corrosive or toxic vapors.

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P022, D003, and F005, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Carbon disulfide is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. A sulfur dioxide scrubber is necessary when combusting significant quantities of carbon disulfide.

A good candidate for liquid injection incineration at a temperature range of 650 to 1,600 °C and a residence time of 0.1 to 2 seconds. A good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 °C and residence times of seconds for liquids and gases, and hours for solids. A good candidate for fluidized bed incineration at a temperature range of 450 to 980 °C and residence times of seconds for liquids and gases, and longer for solids.

For more Disposal Methods (Complete) data for Carbon disulfide (8 total), please visit the HSDB record page.

Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.

ACCIDENTAL RELEASE MEASURES; Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Areas suspected of high concn of carbon disulfide vapor should not be entered because of the explosion hazard.

Carbon disulfide appears as a clear colorless to light yellow volatile liquid with a strong disagreeable odor. Flammable over a wide vapor/air concentration range (1%-50%). Vapors are readily ignited; the heat of a common light bulb may suffice. Insoluble in water and more dense than water. Hence sinks in water. Vapors are heavier than air. Used in the manufacture of rayon and cellophane, in the manufacture of flotation agents and as a solvent.

Explosion Hazard for Carbon Disulfide Reaction To the Editor: We would like to call attention to the danger of explo- sion of carbon disulfide in contact with potassium met- al. On following a recently published procedure (1) for the reduction of carbon disulfide with alkali metals, violent det- onations have occurred in laboratories in France and the United States resulting, in one case, in hospitalization of the personnel involved. The threat of explosion of mixtures of carbon disulfide and potassium or potassium-sodium alloys has previously been noted (2). The Steimecke et al. procedure affords various 1,3-dith- iole-2-thione-4,5-dithiolate salts which have proven to be versatile intermediates in organo-sulfur chemistry. Follow- ing their procedure, no explosions have occurred when sodi- um is substituted as the dissolving metal reductant although we advise caution when handling these dangerous reagents.

CARBON DISULFIDE has an extremely low autoignition temperature. May ignite or even explode when heated. The vapor or liquid has been known to ignite on contact with steam pipes, particularly if rusted [Anon., J. Roy. Inst. Chem., 1956, 80, p.664]. Explosion hazard when exposed to flame, heat, sparks or friction. Mixtures with lithium, sodium, potassium or dinitrogen tetraoxide may detonate when shocked. Potentially explosive reaction with nitrogen oxide, chlorine, permanganic acid(strong oxidizing agents). Vapor ignites in contact with aluminum powder or fluorine. Reacts violently with azides, ethylamine ethylenediamine, ethylene imine. Emits highly toxic fumes of oxides of sulfur when heated to decomposition [Bretherick, 5th ed., 1995, p. 663]. Sodium amide forms toxic and flammable H2S gas with CS2. (714)

Incompatible with air, metals, and oxidants.

Strong oxidizers; chemically-active metals such as sodium, potassium & zinc; azides; rust; halogens; amines [Note: Vapors may be ignited by contact with ordinary light bulb].

Carbon disulfide vapor, alone or mixed with nitrogen, did not decompose explosively in the range 0.4 to 2.1 bar/88 to 142 °C when initialized with high energy sparks or a hot wire at 700 to 900 °C. The endothermic /carbon disulfide/ ... will ... decompose explosively to its elements with mercury fulminate initiation. A screening jacket filled with carbon disulfide was used to surround the reaction tube used in flash photolysis experiments. When the quartz lamp was discharged, some vapor of the disulfide which had leaked out, ignited in the radiation flash and exploded. Care is also necessary with the vapor and other UV sources.

Disposal of 2 L ... /carbon disulfide/ solvent into a rusted iron sewer caused an explosion. Initiation of the solvent-air mixture by rust was suspected. A hot gauze falling from a tripod into a lab sink containing some carbon disulfide initiated two explosions. It is a very hazardous solvent because of its extreme volatility and flammability. The vapor or liquid has been known to ignite on contact with steam pipes, particularly if rusted. When a winchester of the solvent fell off a high shelf and broke behind a rusted steel cupboard, ignition occurred.

CDC-ATSDR Toxicological Profile

IDENTIFICATION AND USE: Carbon disulfide is a clear colorless liquid at room temperature. It is used in the production of viscose fiber and cellophane film. HUMAN STUDIES: The most important health effects for carbon disulfide are coronary heart disease, retinal angiopathy, color discrimination, effects on peripheral nerves, psychophysiological effects, morphological and other central nervous system (CNS) effects, and fertility and hormonal effects. No evidence of carcinogenicity has been observed in epidemiological studies. There are several reports of decreased libido and or impotence among males occupationally exposed to high concentrations of carbon disulfide. Reproductive health hazards for women chronically exposed to carbon disulfide in the workplace are the following: menstrual disorders are more frequent than in the case of the healthy women, the average menopausal age is statistically earlier, and complex disturbances in neurohormonal system including diminished secretion of estrogens and progesterone in ovaries and dehydroepiandrosterone sulfate in the adrenal gland. DNA damage in human buccal cells of workers occupationally long-term exposed to carbon disulfide was monitored with comet assay, and the possibility of DNA damage was significantly higher in exposure group than that in control group. In human sperm exposed to carbon disulfide in vitro, there was a significant increase in the frequency of chromosomal aberrations and in the frequency of chromosomal breaks. ANIMAL STUDIES: Neurological effects such as hind-limb motor difficulties, reduced nerve conduction velocity, and degeneration of nerve fibers were seen in rats exposed to 700 ppm of carbon disulfide for 5 hours a day, 5 days a week, for 12 weeks. Other behavioral effects in rats included decreased responsiveness to a visual stimulus and mild tremors, reactivity in response to handling was increased, and excitability in the open field was decreased. No evidence of carcinogenicity has been reported in long term studies with laboratory animals. Carbon disulfide was not mutagenic to Salmonella typhimurium strains TA98 and TA100 at 300 to 1000 umol nor to Escherichia coli strain WP2 uvrA at 20 to 600 umol with or without metabolic activation, nor in Drosophila melanogaster at 200 to 800 ppm. However, DNA damage in mice sperm was detected with single-cell gel electrophoresis assay. In experimental animals, carbon disulfide is embryotoxic and fetotoxic at high concentrations and is teratogenic at exposure levels toxic to the dam. ECOTOXICITY STUDIES: Reduced hatching and developmental effects, particularly notochord deformities, were observed in the frog Microhyla ornata exposed to carbon disulfide.

Carbon disulfide is a potent nerve toxin and also affect liver enzymes, particularly those related to lipid metabolism. The increases in serum cholesterol that are sometimes seen following carbon disulfide exposure may be a result of increased hepatic cholesterol synthesis. The primary target of carbon disulfide appears to be the nervous system. Neurophysiological and behavioral effects as well as pathomorphology of peripheral nervous system structures have been reported in humans. Moreover, carbon disulfide metabolites of the thiocarbamate type inhibit aldehyde anhydrase. (L592, A215)

The substance is toxic to aquatic organisms.

Carbon disulfide's production and use in the manufacture of rayon, carbon tetrachloride, xanthogenates, soil disinfectants, electronic vacuum tubes, and as a solvent for phosphorus, sulfur, selenium, bromine, iodine, fats, resins, rubbers and manufacture of flotation agents may result in its release to the environment through various waste streams. Its former use in the US as an insecticide for fumigation of nursery stock and soil treatment against insects and nematodes, resulted in its direct release to the environment. Carbon disulfide is a natural product of anaerobic biodegradation and is released to the atmosphere from oceans and landmasses as well as geothermal sources. The ocean appears to be a major source of carbon disulfide. Coastal and marshland areas of high biological activity are also a major source. If released to air, a vapor pressure of 359 mm Hg at 25 °C indicates carbon disulfide will exist solely as a vapor in the ambient atmosphere. Vapor-phase carbon disulfide will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 5.5 days. Carbon disulfide has a weak UV adsorption band at 317 nm and, therefore, may be susceptible to direct photolysis by sunlight. However, photolysis is not considered to be an important loss mechanism for the chemical. If released to soil, carbon disulfide is expected to have very high mobility based upon an estimated Koc of 48. Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry's Law constant of 1.44X10-2 atm-cu m/mole at 24 °C. Carbon disulfide may volatilize from dry soil surfaces based upon its vapor pressure. Utilizing the Japanese MITI test, 2% of the Theoretical BOD was reached in 4 weeks indicating that biodegradation is not an important environmental fate process in soil or water. If released into water, carbon disulfide is not expected to adsorb to suspended solids and sediment in the water column based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon carbon disulfide's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 2.6 hours and 3.5 days, respectively. BCF values of <6.1 and <60 in carp suggest that bioconcentration in aquatic organisms is low to moderate. Carbon disulfide hydrolyzes slowly to carbon dioxide and hydrogen disulfide in alkaline solutions. The half-life for hydrolysis at pH 9 is approximately 1.1 years, indicating that hydrolysis is not an important environmental fate process. Occupational exposure to carbon disulfide may occur through inhalation and dermal contact with this compound at workplaces where carbon disulfide is produced or used. As carbon disulfide occurs ubiquitously in the environment, the general population is exposed to this compound. Primary routes of exposure to carbon disulfide are through inhalation of ambient air and ingestion of food containing this compound. (SRC)

Minute amounts of carbon disulfide occur in coal tar and in crude petroleum(1).

The background global concentration of carbon disulfide is approximately 0.047 ug/cu m(1). The ocean appears to be a major global source of carbon disulfide(2-4). Current data suggest that coastal areas and other areas of high biological productivity have greater fluxes of carbon disulfide than the open ocean(3). Emissions from the oceans have been estimated to be 6X10+11 g/yr(3).

The microbial reduction of sulfates in soil produces fluxes of carbon disulfide. The annual global emission from this source has been estimated to be 9X10+11 g(1). Other natural sources include volcanic emissions, estimated to be 2X10+10 g/yr, and marshlands, estimated emissions 1X10+11 g/yr(1). Carbon disulfide was emitted briefly from an aerobic loam soil(2). Emissions from tidal marshes is greatest when the soil moisture is at field capacity(2). Fluxes of carbon disulfide from a salt marsh was measured as 0.2 and 1.13 g Sulfur/sq m-yr and inland soil 0.001 g Sulfur/sq m-yr(3). However, the overall contribution of inland soil is much higher(3). Diurnal variation in emissions rates correlate loosely with soil temperature and solar irradiation(4).

Some higher plants are known to emit carbon disulfide(1,2). The principle source is the tree roots(2). Carbon disulfide emissions rates were highest in the early- to mid-afternoon and lowest during the early morning. Carbon disulfide emissions from a temperate pine forest increased nine-fold when nitrogen fertilizers were added(3). However, similar increases were not observed in a temperate hardwood forest(3).

Carbon disulfide's production and use in the manufacture of rayon, carbon tetrachloride, xanthogenates, soil disinfectants, electronic vacuum tubes, and as a solvent for phosphorus, sulfur, selenium, bromine, iodine, fats, resins, rubbers(1) and manufacture of flotation agents(2) may result in its release to the environment through various waste streams(SRC). Its former use in the US(3) as an insecticide used for fumigation of nursery stock and soil treatment against insects and nematodes(4) resulted in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 48(SRC), determined from a log Kow of 1.94(2) and a regression-derived equation(3), indicates that carbon disulfide is expected to have very high mobility in soil(SRC). Volatilization of carbon disulfide from moist soil surfaces is expected to occur(SRC) given a Henry's Law constant of 1.44X10-2 atm-cu m/mole at 24 °C(4). Carbon disulfide is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 359 mm Hg(5). Utilizing the Japanese MITI test, 2% of the Theoretical BOD was reached in 4 weeks(6) indicating that biodegradation is not an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 48(SRC), determined from a log Kow of 1.94(2) and a regression-derived equation(3), indicates that carbon disulfide is not expected to adsorb to suspended solids and sediment in the water column(SRC). Carbon disulfide is expected to volatilize rapidly from water surfaces(3) based on a Henry's Law constant of 1.44X10-2 atm-cu m/mole at 24 °C(4). Estimated volatilization half-lives for a model river and model lake are 2.6 hours and 3.5 days, respectively(SRC). According to a classification scheme(5), BCFs of <6.1 and <60 in carp at 50 and 5 ug/L, respectively(6) suggest that bioconcentration in aquatic organisms is low to moderate(SRC). Utilizing the Japanese MITI test, 2% of the Theoretical BOD was reached in 4 weeks(6) indicating that biodegradation is not an important environmental fate process in water(SRC). Hydrolysis is not expected to be an important environmental fate process based on a half-life of over 1 year under alkaline conditions(7).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), carbon disulfide, which has a vapor pressure of 359 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase carbon disulfide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 5.5 days(SRC), calculated from its rate constant of 2.9X10-12 cu cm/molecule-sec(3). Carbon disulfide has a weak UV adsorption band at 317 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). However, photolysis is not considered to be a relevant loss mechanism for the chemical(SRC).

AEROBIC: It has been demonstrated that the adsorption of carbon disulfide by moist unsterilized soil increases sharply after approximately 3 hr and the time for complete sorption of the gas decreases with repeated dosing(1). This behavior does not occur with air-dried or sterilized soil and has been ascribed to microbial utilization of the chemical(1). Carbon disulfide is oxidized by some heterotrophs(2). Carbon disulfide, present at 100 mg/L, reached 2% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(3).

The rate constant for the vapor-phase reaction of carbon disulfide with photochemically-produced hydroxyl radicals is 2.9X10-12 cu cm/molecule-sec at 24 °C(1). This corresponds to an atmospheric half-life of about 5.5 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(SRC). Observed temporal variability and vertical gradients suggest that the tropospheric lifetime of carbon disulfide is quite short(2). If the atmospheric concentration of carbon disulfide at 6.1 km altitude is typical for marine boundary layer levels, the sharp decrease in concn at higher altitudes supports the concept of a photochemical lifetime of a month or less in the troposphere(2). The tropospheric half-life determined from estimates of sources and global burdens of the chemical is 8.9 days(4). Carbon disulfide has a weak UV adsorption band at 317 nm(3); however, photolysis is not considered to be an important loss mechanism(4). The rate constant for the vapor-phase reaction of carbon disulfide with atomic oxygen is 3.6X10-12 cu cm/molecule-sec at 25 °C(5). This corresponds to an atmospheric half-life of about 8.9 days(SRC) assuming an atmospheric concentration of atomic oxygen is 2.5X10+5 radicals/cu cm(5,6). The rate constant for the reaction of carbon disulfide with hydroxyl radicals in aqueous solution is 8.0X10+9 L/mol sec at pH 7.6(7). This corresponds to a half-life of about 100 days(SRC) at an average aqueous hydroxyl radical concentration of 1X10-17 mol/L(8).

Carbon disulfide hydrolyzes to carbon dioxide and hydrogen disulfide in alkaline solutions(1). The half-life for hydrolysis at pH 9 extrapolated from measurements at higher pH is 1.1 yr (1). It is stable in oxygenated seawater for >10 days(2).

BCFs of <6.1 and <60 were measured in carp for carbon disulfide at concentrations of 50 and 5 ug/L, respectively(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is low to moderate(SRC).

The Koc of carbon disulfide is estimated as 48(SRC), using a log Kow of 1.94(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that carbon disulfide is expected to have very high mobility in soil(SRC). The average adsorption of carbon disulfide after 10 minutes by 4 air-dried soils was 46% but only 12% by the same soils at 50% water-holding capacity(4). However, after 8 hrs the rate of adsorption was greater by moist soil, but only when the soil was unsterilized(4). Further experiments suggest that this "adsorption" in moist soils was the result of microbial action(4).

The Henry's Law constant for carbon disulfide is 1.44X10-2 atm-cu m/mole at 24 °C(1). This Henry's Law constant indicates that carbon disulfide is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) (2) is approximately 2.6 hours(SRC). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) (2)is approximately 3.5 days(SRC). Carbon disulfide's Henry's Law constant(1) indicates that volatilization from moist soil surfaces is expected to occur(SRC). The potential for volatilization of carbon disulfide from dry soil surfaces may exist(SRC) based upon the vapor pressure of 359 mm Hg(3).

GROUNDWATER: Groundwater samples collected from the Lipari Landfill, NJ in 1984, contained carbon disulfide at <50 ppb(1).

DRINKING WATER: Carbon disulfide was tested for but not detected in drinking water samples from nine cities in the US and one rural well; no detection limit stated(1). It was detected, but not quantified, in New Orleans(2), Miami, and Cincinnati drinking water(3). Water samples obtained from collapsible fabric tanks used for potable water storage for U.S. Army field exercises in 1982 and 1987 contained a maximum carbon disulfide concentration of 33 ug/L(4). Carbon disulfide was detected in a well in Southern NJ at a level of approximately 3 ug/L(5).

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P022, D003, and F005, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations.
