12.2 Persistence and degradability
AEROBIC: In a test for primary biodegradation, 2-naphthylamine was not degraded in chernozem soil after 90 days at an initial concentration of 500 mg/kg(1). The maximum mineralization rate for 2-naphthylamine (conc. 50 ug/g) in a soil/water suspension over 220 days was 0.12 ug/g-day during a short initial phase and 0.027 ug/g-day during a longer second phase(2). Addition of fresh amounts of 2-naphthylamine (conc. 50 ug/g) at 220 days restored the mineralization to the initial phase rate value. The recalcitrance of aminonaphthalenes in soil has been attributed to their ability to form complexes with soil matter which, to a large extent, renders them biologically unavailable(3).
12.3 Bioaccumulative potential
An estimated BCF of 11 was calculated for 2-naphthylamine(SRC), using a log Kow of 2.28(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
The measured Koc for 2-naphthylamine is 1,000(1). According to a classification scheme(2), this Koc value suggests that 2-naphthylamine is expected to have low mobility in soil. Results of a batch equilibrium study with various soils indicated that 1-naphthylamine, which is structurally analogous to 2-naphthylamine, binds to soil in two phases with an initial rapid and reversible equilibrium established between the amine and the inorganic and organic components of soil followed subsequently by a strong association with the humic fraction of soil via covalent binding(3,4). Aminonaphthalenes are known to form complexes with soil matter(5). The pKa of 2-naphthylamine is 4.16(6), indicating that this compound will partially exist in cation form in the environment.
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.
