AEROBIC: The results of biodegradability screening studies for 2-chloroaniline are conflicting with results ranging from no degradation to rapid degradation using soil, sewage, activated sludge and fresh water inocula(SRC). 2-Chloroaniline was found to be resistant to microbial degradation using the standard biodegradability test of the Japanese Ministry International Trade and Industry (MITI), a BOD test utilizing a mixed inoculum of activated sludge, sewage, and surface water(1,2). Only 2.7% of the 2-chloroaniline (100 ppm) degraded in a 2-week period in the MITI test(2). A 36% BODT was measured over a 190 hour incubation period with a Warburg respirometer(3). Half-lives greatly in excess of 4 weeks in both adapted and non-adapted inoculum were observed using the Repetitive Die Away (semistatic system) and Pitter (dynamic system) tests(4). No biodegradation was observed using modified procedures of the OECD and MITI test methods(5,6). Results of standard biodegradation tests were reported as follows: Coupled units, 5-6% DOC removal; Zahn-Wellens, 94% DOC removal; MITI, 0% BODT; Sturm, 0% CO2 evolution, 9% DOC removal; Closed bottle, 0% BODT(7). Another investigator obtained 85% DOC removal in 11 days in the Zahn-Wellens test(8). 2-Chloroaniline (2 mg/L) was found to be not readily biodegradable with a 10% BOD observed after 5 days in a mixed inoculum of river water collected from the Songhua River in China(9). Incubation of 2-chloroaniline in soil for 14 days resulted in formation of dichloroazobenzene, but no dichloroazobenzene was formed using sterilized soil(10). 100% loss of UV absorbance by microbial degradation in a mineral salts solution, with a soil inoculum, required an excess of 64 days(11). When 2-chloroaniline (3 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(12). The percent of 2-chloroaniline remaining in soil after 2 and 8 weeks were 40 and 20%, respectively(12).
12.3 Bioaccumulative potentialThe average BCFs in the whole body of carp exposed to 2-chloroaniline in flow-through experiments (25°C, 12L/hr) for 24 to 336 hours at high (16.1 ug/L) and low (0.83 ug/L) exposure levels were 2.0 and 3.7, respectively(1). Uptake was rapid in static tests (0.19 umol/L, 26°C) on zebrafish and a BCF of 15.3 was obtained for 24 hour exposure(2). Log BCF of 2-chloroaniline in fish were experimentally determined to be less than 2.0 using the Japanese MITI test procedures(3). In an 8-week test performed at two concentration levels, the BCF of 2-chloroaniline in carp was 5.4-9.0 (0.1 ppm) and <14-32 (0.01 ppm)(4). According to a classification scheme(5), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC), provided the compound is not altered physically or chemically once released into the environment.
12.4 Mobility in soilThe Koc of 2-chloroaniline is estimated as 260(SRC), using a log Kow of 1.9(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-chloroaniline is expected to have moderate mobility in soil. 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).

13.Disposal considerations 13.1 Disposal methods ProductThe 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.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
