Persistence and degradability
AEROBIC: Using water samples containing bacteria acclimated to 2,4,6-trichloroaniline, a first-order rate decay of 0.206 day-1 was determined for the degradation of 2,4,6-trichloroaniline(1), with a half-life of 3.36 days(SRC). Negative inductive effects given by chlorosubstitutions in 2,4,6-positions operated strongly and prevented the enzymic conversion of 2,4,6-trichloroaniline using peroxidase enzymes(2). In a soil-bound form, residues of 2,4,6-trichloroaniline underwent aerobic mineralization more readily by soil micro flora than in a free state(3). Chemical binding of aniline residues to the soil organic matter effectively competes with the polymerization process by soil bacteria. Chemical binding to humic compounds acts greatly to retard mineralization(4).
Bioaccumulative potential
A BCF of 3,630 was measured for 2,4,6-trichloroaniline(1) when exposed to fish for a 96 hr period. This suggests the potential for bioconcentration in aquatic organisms is very high, according to a classification scheme(2).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2,4,6-trichloroaniline can be estimated to be about 2,400(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,4,6-trichloroaniline is expected to have slight mobility in soil. Also, covalent binding to humic substances is an important process in the formation of soil-bound residues of chlorinated anilines. Additionally, other mechanisms of soil-binding, such as entrapping of residues into cavities within the humus structure, or binding to mineral constituents, may also contribute to the phenomenon of bound residues of anilines in soil(3). Aromatic amines (such as various trichloro aniline isomers) have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solution. The initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures followed by oxidation of the product to give an amino-substituted quinone. These processes represent pathways by which aromatic amines may be converted to latent forms in the biosphere(4). There appears a rapid and spontaneous binding to soil organic matter and to purified humic and fulvic acid preparations. Therefore, a build up of 2,4,6-trichloroaniline in agricultural soils may occur(5).
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
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.
Containers 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.
