Persistence and degradability
AEROBIC: N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(1).
Bioaccumulative potential
BCFs ranging from 101 to 242 and 51 to 253 (species unidentified) were measured using 0.1 and 0.01 mg/liter of N,N-diphenylamine, respectively, and a 8-week study period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
The Koc of N,N-diphenylamine is estimated as 1,900(SRC), using a log Kow of 3.50(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N,N-diphenylamine is expected to have low mobility 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.
