12.2 Persistence and degradability


12.3 Bioaccumulative potential

The average BCFs in the whole body of carp exposed to 4-chloroaniline in flow-through experiments (25°C, 12 L/hr) for 24 to 336 hr at high (10.4 ug/L) and low (0.30 ug/L) exposure levels were 0.8 and 1.7, respectively(3). Excretion was rapid with depuration rates and half-lives of 0.16/hr and 4.3 hr, respectively(3). Therefore, 4-chloroaniline should not bioconcentrate in fish. Uptake was rapid in static tests (0.20 umol/L, 26°C) on zebrafish and a BCF of 8.1 was obtained for 24 hr exposure(4). Elimination was best described by a two compartment first order model(4). After 53 hr of depuration, the concn of 4-chloroaniline in the zebrafish declined to 12.0% of the steady state value. The log BCF in Golden orfe was <1.30 for 3 day exposure(1). The 24-hr log BCF in green alga was 3.08 (dry wt basis(2)) and 2.42 (wt weight basis(1)). A BCF of 13.4 was reported for guppy (Poecilia reticulata)(5). According to a classification scheme(6), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc for 5 Belgium soils ranged from 230-469(1). The adsorption isotherm was not linear and the exponent in the Freundlich adsorption isotherm averaged 0.70(1). The Koc for 5 German soils ranged from 96 to 1,530 with the Freundlich exponent ranging from 0.92 to 1.23(2). From adsorption studies on three soils with radically different organic carbon and clay contents, it was shown that the percent (14)C labeled 4-choloroaniline that was bound increased with the organic carbon content of the soil and decreased with its clay content(3). Stronger binding at low concns, particularly with the soil of low organic carbon content, suggests that there are a limited number of available binding sites on the soil(3). At the lower concn (5ppm), percent binding ranged from 46-78%(3). The Koc to colloidal organic matter in ground water was high, 5,550, suggesting that adsorption onto this microparticulate matter could effectively increase the solubility and leaching of 4-chloroaniline into landfill groundwater(4). According to a classification scheme(5), Koc values between 50-150 suggest that 4-chloroaniline is expected to have high mobility in soil, Koc values >500 to >5000 suggest 4-chloroaniline is expected to have low to no mobility in soil. Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(7,8), suggesting that mobility may be much lower in some soils(SRC). Adsorption of 4-chloroaniline by 5 soils was studied in the lab; adsorption decreased with the depth of the soil sample, due to decreased organic carbon(6). Adsorption coefficients of 4-chloroaniline and 4 other organic compounds for organic and inorganic materials and natural soils were determined(2). With few exceptions, the organic constituents of the soils were mainly responsible for their adsorption properties(2). Cellulose appeared to be a well-suited model adsorbent for simulating the relative adsorption behavior of the chemicals(2). The pKa of 4-chloroaniline is 3.98(9), indicating that this compound will primarily exist in its nonionic form in the environment.

12.5 Other adverse effects
