This chemical is combustible. (NTP, 1992)

Combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Health HazardsSYMPTOMS: Symptoms of exposure to this chemical may include methemoglobinemia and, in large concentrations cyanosis; dermatitis, liver and kidney damage, and death.
Hazards Summary · 1 Eintrag

In the United Kingdom between 1961 and 1980, chloroaniline, p-toluidine, nitrobenzene, and nitrochlorobenzene were the most common industrial causes of methemoglobinemia. Dermal exposure was a more frequent route of toxicity than inhalation with these compounds. (Ellenhorn, M.J. and D.G. Barceloux. Medical Toxicology - Diagnosis and Treatment of Human Poisoning. New York, NY: Elsevier Science Publishing Co., Inc. 1988.) A skin and eye irritant; Can induce methemoglobinemia; [ICSC] Danger of skin sensitization; [MAK]

Environmental Fate · 3 Einträge

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that 3-chloroaniline is expected to have moderate mobility in soil(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4,5), suggesting that mobility may be much lower in some soils(SRC). 3-Chloroaniline may undergo covalent chemical bonding with humic materials which results in its chemical alteration and tight adsorption(6). There is evidence to suggest that this complexing may extend the residual life of these substances in soil for as much as 10 years(7). Due to this covalent bonding, significant leaching in soil systems is not generally expected to occur(SRC). The pKa of 3-chloroaniline is 3.52(10), indicating that this compound will primarily exist in its nonionic form in the environment. Volatilization of 3-chloroaniline from moist soil surfaces is expected to occur(SRC) given a Henry's Law constant of 1.0X10-6 atm-cu m/mole(8). However, adsorption to soil is expected to attenuate volatilization(SRC). 3-Chloroaniline is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.066 mm Hg(9). 3-Chloroaniline may degrade in soil by chemical and microbial processes(11). When 3-chloroaniline (30 ppm) was incubated in Guelph loam with water added to 60% water-holding capacity, levels declined rapidly for 2 weeks after which time the rate of loss decreased(11). The percent of 3-chlororaniline remaining in soil after 2 and 8 weeks were 38% and 18%, respectively(11).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 250(SRC), determined from a log Kow of 1.88(2) and a regression-derived equation(3), indicates that 3-chloroaniline may adsorb to suspended solids and sediment(SRC). In addition, 3-chloroaniline may undergo chemical bonding with humic materials in the water column and in the sediment(4). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.0X10-6 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 42 and 310 days, respectively(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(13,14), and volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The pKa of 3-chloroaniline is 3.52(6), indicating that this compound will primarily exist in its nonionic form in the environment. According to a classification scheme(7), measured BCF values ranging from 0.8 to 11.5(8,9) suggests the potential for bioconcentration in aquatic organisms is low(SRC). In a 3-day cultivation test using 2 different river waters from Japan and two different sea waters, 50% of initial 3-chloroaniline was degraded; the degradation was paralleled by growth of microbes(9,10). A biotransformation half-life of 0.4 year was determined for 3-chloroaniline in laboratory studies using two pond and one river water samples obtained near Athens, GA(12). Irradiation of an aqueous solution of 3-chloroaniline in a quartz tube with a fluorochemical lamp (wavelengths above 300 nm) resulted in a photodegradation half-life of 2.6 hours(14).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 3-chloroaniline, which has a vapor pressure of 0.066 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 3-chloroaniline 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 5.1 hours(SRC), calculated from its rate constant of 7.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 3-Chloroaniline absorbs light with wavelengths >290 nm(4) and may be susceptible to direct photolysis by sunlight(SRC).

Food Survey Values3-Chloroaniline was detected in several samples of potato peels, 0.18-0.36 ppb, from potatoes obtained from various geographic locations(1).
Adverse EffectsMethemoglobinemia - The presence of increased methemoglobin in the blood; the compound is classified as primary toxic effect.
Exposure RoutesThe substance can be absorbed into the body by inhalation, through the skin and by ingestion.
Ecotoxicity Excerpts · 1 Eintrag

/AQUATIC SPECIES/ 21 day Daphnia reproduction tests were conducted in line with the provisional procedure proposed by the Federal Environmental Agency, as of Jan 1, 1984. Groups of 20, 24-hr old Daphnia magna Straus were exposed to 6.3 to 800 ug/L 3-chloroaniline in semi-static test vessels. Parent animals in the test and control vessels had to be pipetted 3 times/wk in freshly prepared test and control media at the corresponding concentration level. The no observed effect concentration (NOEC) was determined from the parameters of mortality of the parent animals, reproduction rate and appearance of the first offspring during the test period. In preliminary acute Daphnia tests, the 24 hr EC50 was 0.9 mg/L for 3-chloroaniline, the EC0 was 0.40 mg/L. The nominal 21 day no observed effect concn was 0.013 mg/L, with the more sensitive parameters being reproductive rate and the appearance of first offspring.

Atmospheric Standards · 1 Eintrag

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. m-chloroaniline is produced, as an intermediate or a final product, by process units covered under this subpart.
