5.2 Specific hazards arising from the chemical

Ignition temperature dangerously low: 212F. Vapors may be ignited by contact with ordinary light bulb, when heated to decomposition, it emits highly toxic fumes of oxides of sulfur. When heated to decomposition, emits highly toxic fumes of sulfur oxides and can react vigorously with oxidizing materials. Avoid air, rust, halogens, metal azides, metals, oxidants; when exposed to heat or flame reacts violently with aluminum, chlorine, azides, hypochlorite, ethylamine diamine, ethylene imine, fluorine, metallic azides of lithium, potassium, cesium, rubidium and sodium, nitrogen oxides, potassium, zinc and (sulfuric acid plus permanganate). Decomposes on standing for a long time. (EPA, 1998)

5.3 Special protective actions for fire-fighters

10.3 Possibility of hazardous reactions

Carbon disulfide vapor is explosive, igniting spontaneously on contact with sparks or at temperatures above 147 degrees C.The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.CARBON DISULFIDE has an extremely low autoignition temperature (125°C). 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)

Reproductive toxicity

Reproductive effects, such as decreased sperm count and decreased libido in men and menstrual disturbances in women, have been reported from occupational settings involving inhalation exposure to carbon disulfide. (-) Developmental effects, including skeletal and visceral malformations, embryotoxicity, and functional and behavioral disturbances, have been observed in several animal studies across a wide exposure range. Pharmacokinetic studies indicate that carbon disulfide and its metabolites cross the placenta and localize in the target organs of the fetus (brain, blood, liver, and eyes).

Aspiration hazard

no data available

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (water flea); Concentration: 10 mg/L/24 hr; Condition: not specified; Effect: inhibition of the mobility
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

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 and the Japanese MITI test(3).

12.3 Bioaccumulative potential

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).

12.4 Mobility in soil

The Koc of carbon disulfide is estimated as approximately 270(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 moderate mobility in soil(SRC). The avg 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 hr 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 is the result of microbial action(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
