- Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age <24 hr); Conditions: freshwater, static, pH 7.8-8.1, dissolved oxygen 96-99% saturated; Concentration: 1220 ug/L for 24 hr (95% confidence interval: 520-2920 ug/L); Effect: intoxication, immobilization /98% purity

12.2 Persistence and degradability
AEROBIC: p-Aminodiphenylamine, present at 2.4 mg/L biodegraded 0, 24, and 28% in 5, 10, and 20 days, respectively, using an adapted activated sludge inoculum in a DEV test(1). p-Aminodiphenylamine, present at 100 mg DOC/L, reached 58% DOC after 3 hours using a mixed, non-adapted activated sludge inoculum in a Zahn-Wellens test(1).
12.3 Bioaccumulative potential
An estimated BCF of 5.1 was calculated for p-aminodiphenylamine(SRC), using an estimated log Kow of 1.82(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of p-aminodiphenylamine can be estimated to be 3.1X10+3(SRC). According to a classification scheme(2), this estimated Koc value suggests that p-aminodiphenylamine is expected to have slight mobility in soil. The pKa of p-aminodiphenylamine is 5.20(3), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
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.
