Persistence and degradability
AEROBIC: N,N'-diphenyl-p-phenylenediamine, present at 100 mg/l, reached 0.2% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l in the Japanese MITI test(1).
Bioaccumulative potential
An estimated BCF of 260 was calculated for N,N'-diphenyl-p-phenylenediamine(SRC), using an estimated log Kow of 4.0(1) and a regression-derived equation(2). The BCF for N,N'-diphenyl-p-phenylenediamine was determined to be greater than 100(4). The bioconcentration of N,N'-diphenyl-p-phenylenediamine in the lipids of fish (8 week exposure period) were between 264-1418 and 495-2146 for test concentrations of 0.1 mg/l and 0.01 mg/l, respectively(5). According to a classification scheme(3), BCF values of 500 to 2000 are low and from 50 to 150 are high.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for N,N'-diphenyl-p-phenylenediamine can be estimated to be 1.3X10+5(SRC). According to a classification scheme(2), this estimated Koc value suggests that N,N'-diphenyl-p-phenylenediamine is expected to be immobile in soil(SRC).
Other adverse effects
no data available
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.
