Persistence and degradability
AEROBIC: N-Phenyl-1-naphthylamine, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). In contrast, another test showed a 50% theoretical BOD in 5 days using a freshwater inoculum(2). Using an activated sewage inoculum, N-phenyl-1-naphthylamine (concentration of 2 ug/g) reached 70% of its theoretical BOD in 2 days(2). In screening tests, N-phenyl-1-naphthylamine present in a concentration of 2 ug/mL, reached 50% of its theoretical BOD in 10 days in Oneida Lake, NY water(2). Using acclimated lake water supplemented with nutrient broth, N-phenyl-1-naphthylamine (concentration of 2 ppm) reached 90% of its theoretical BOD after 10 days. N-Phenyl-1-naphthylamine was observed to degrade in a soil study, based on carbon dioxide evolution at rates of 7 and 17% 14CO2 evolution (40 nCi of 14CO2%-test compound/g soil) after 2 and 11 days, respectively(2).
Bioaccumulative potential
BCF ranges of 427-2,730 and 889 to 2,490 at 0.1 and 0.01 mg/L, respectively, were measured for N-phenyl-1-naphthylamine(SRC), using orange-red killifish (Oryzias latipes) which were exposed over an 8-week period(1). BCFs ranging from 432 to 1,285 (relative to radioactivity) and 233 to 694 (relative to test compound) were determined in a flow-through system for bluegill sunfish (Lepomis macrochirus) at steady state(2). According to a classification scheme(3), these BCF values suggest bioconcentration in aquatic organisms is high to very high(SRC), provided the compound is not altered physically or chemically once released into the environment.
Mobility in soil
The Koc of N-phenyl-1-naphthylamine is estimated as 4,600(SRC), using a measured log Kow of 4.2(1), and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N-phenyl-1-naphthylamine is expected to have slight mobility in soil. The pKa of N-phenyl-1-naphthylamine is 4.93 at 25 deg C(4) indicating that this compound will partially exist in the cation form in the environment(3) Since N-phenyl-1-napthylamine exists in the protonated form, it will adsorb more strongly to organic carbon and clay than its neutral counterparts(5).
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.
