12.Ecological information 12.1 Toxicity- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Using an initial concn of 100 mg/L N-phenyl-2-naphthylamine, 0 %BOD was observed after a 2 week period in a biodegradation screening test using 30 mg/L sludge(1). N-Phenyl-2-naphthylamine, initial concn of 100 ppm, exhibited a 0-29 % Theoretical BOD in a Japanese MITI test after 14 days of incubation at 25°C(2). N-phenyl-2-naphthylamine was shown to degrade to beta-naphthylamine in a screening study using activated sludge inoculum at 21°C(3). In this study, 44.2 and 9.3 %CO2 production was observed in 1 day at initial concns of 2 and 5 ppm, respectively(3). At an initial concn of 8 ppm, N-phenyl-2-naphthylamine was observed to be inhibitory to microorganisms under the same test conditions(3). Furthermore, adsorption to solids was found to occur and, hence, reduce biodegradation(3).
12.3 Bioaccumulative potentialThe BCF value for N-phenyl-2-naphthylamine was determined to be 147 with the fathead minnow (Pimephales promelas) in a 32 day exposure flow-through test of Lake Superior water at 25°C(1).
12.4 Mobility in soilAromatic amines have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solution; the initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures followed by oxidation of the product to give an amino-substituted quinone; these processes represent pathways by which aromatic amines may be converted to latent forms in the biosphere(4). In the absence of covalent bonding, one can estimate the adsorption potential based on the Koc value. Based on an experimental log octanol-water partition coefficient of 4.38(2) and a recommended regression-derived equation(1), the Koc value for N-phenyl-2-naphthylamine can be estimated to be 12,500(SRC). According to a suggested classification scheme(3), this Koc value indicates that N-phenyl-2-naphthylamine will be immobile in soil.
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.
