12.2 Persistence and degradability
The half-life of N-nitrosodiphenylamine in 86 g/kg sludge soil produced from a wood preserving process was determined to be 88.9 days, from an initial concentration of 697 mg/kg and a final concentration of 19 mg/kg after 287 days; the half-life of N-nitrosodiphenylamine in 172 g/kg sludge soil produced from a wood preserving process was determined to be 166.4 days, from an initial concentration of 887 mg/kg and a final concentration of 58 mg/kg after 287 days(1). In a static biodegradation test that used domestic wastewater as the inoculum, the percent of N-nitrosodiphenylamine biodegraded in the original culture and first, second and third subcultures after 7 days incubation per culture was: (10 mg/l initial concentration N-nitrosodiphenylamine) 47, 63, 95, and 98; at 5 mg/l initial concentration N-nitrosodiphenylamine: 87, 100, 92, and 100, respectively(2). Removal of N-nitrosodiphenylamine at two industrial activated sludge treatment plants averaged >84 percent at an average influent concentration of 5.3 ug/l(3). At an industrial aerated lagoon, 67 percent of an initial N-nitrosodiphenylamine concentration of 3 ug/l was removed(3). Sixty-eight percent of N-nitrosodiphenylamine added to soil at a concentration of 354 ug/g soil was degraded by the end of a 30 day incubation at 30°C in the dark(3). In soil amended with wheat straw (organic matter content increased from 2.16 to 17.5 percent), N-nitrosodiphenylamine disappeared completely by day 10 of the incubation(4).
12.3 Bioaccumulative potential
A maximum bioconcentration factor (BCF) of 217 was reported for N-nitrosodiphenylamine in Lepomis macrochirus (bluegill sunfish) exposed to an average N-nitrosodiphenylamine concentration of 9.21 ug/l for 14 days(1). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is moderately high(SRC).
12.4 Mobility in soil
The Koc of N-nitrosodiphenylamine is estimated as approximately 1,200(SRC), using an experimental log Kow of 3.13(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that N-nitrosodiphenylamine is expected to have low mobility in soil(SRC).
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.
