12.2 Persistence and degradability
In the Japanese MITI test, using an initial concn of 100 ppm 2-chlorotoluene, <30% of the theoretical BOD was reached in 14 days using an activated sludge inoculum(1,2). In the modified MITI test, using an initial concentration of 100 ppm 2-chlorotoluene, 0% of the theoretical BOD was reached in 14 days(3). A second order rate constant for the microbial degradation of 2-chlorotoluene in natural water was experimentally determined to be 2.7X10-11 L/organism-hr(4). Microorganisms capable of degrading 2-chlorotolune were isolated from soil samples collected at a landfill site used for the disposal of chlorinated organic wastes(5). A microbial blend of 10 different bacteria and 2 fungi was used to degrade 2-chlorotoluene at a concentration of 200 mg/l; complete biodegradation occurred in 3 days(6).
12.3 Bioaccumulative potential
Carp exposed to 2-chlorotoluene at 0.045 and 0.45 mg/L had measured BCF values of 20-112 and 41.6-87.2, respectively(1). An estimated BCF value of 230 was calculated for 2-chlorotoluene(SRC), using a measured log Kow of 3.42(2) and a recommended regression-derived equation(3). According to a recommended classification scheme(4), these BCF values suggest that bioconcentration of 2-chlorotoluene in aquatic organisms may occur(SRC).
12.4 Mobility in soil
Measured soil adsorption coefficients (Koc) for 2-chlorotoluene ranged between 170-880, the average value was 370(1). According to a recommended classification scheme(3), these Koc values suggest that 2-chlorotoluene will have low to moderate mobility in soil(2,SRC).
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.
Contaminated packaging
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.
