Persistence and degradability
AEROBIC: N,N-Dimethylacetamide, present at 100 mg/l reached 28% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(1). N,N-Dimethylacetamide, present at 30 mg/l, reached 80% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 100 mg/l and the Japanese MITI test(1). In other studies, N,N-dimethylacetamide, present at 400 mg/l, reached 96% of its theoretical TOC in 5 days using industrial activated sludge(2). These results from laboratory studies suggest that N,N-dimethylacetamide will biodegrade in the environment(SRC).
Bioaccumulative potential
An estimated BCF of 3 was calculated for N,N-dimethylacetamide(SRC), using a log Kow of -0.77(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).
Mobility in soil
The Koc of N,N-dimethylacetamide is estimated as 9(SRC), using a measured log Kow of -0.77(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N,N-dimethylacetamide is expected to have very high mobility in soil(SRC).
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.
