12.Ecological information 12.1 Toxicity- Toxicity to fish: LC50 Brachydanio rerio (Zebrafish) 2.2 mg/L/48 hr /Conditions of bioassay not specified
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
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).
12.3 Bioaccumulative potentialBCFs 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).
12.4 Mobility in soilThe 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).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
