12.2 Persistence and degradability
AEROBIC: bis(4-Aminophenyl) sulfide exhibited a half-life of 10 to 12 hours in activated sludge, at an incubation temperature of 35°C, pH of 6.9 and starting concentration of 50 ug/L in a 7 day test(1).
12.3 Bioaccumulative potential
An estimated BCF of 13 was calculated in fish for bis(4-aminophenyl) sulfide(SRC), using a log Kow of 2.18(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 bis(4-aminophenyl) sulfide can be estimated to be 2,100(SRC). According to a classification scheme(2), this estimated Koc value suggests that bis(4-aminophenyl) sulfide is expected to have slight mobility in soil.
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.
