AEROBIC: 51% of the theoretical BOD was achieved for dimethylamine with an activated sludge during a 2 week incubation period(1). Dimethylamine was biodegraded 69-89% in three Saskatchewan soils during a 7 day incubation period(2). In a screening study, dimethylamine completely degraded at 10 ppm with both an activated sludge and freshwater/sediment inoculum(3); after 5 days incubation, 70 and 80% of theoretical BOD was consumed in the activated sludge and the sediment, respectively(1). Inhibition was noted at 50 ppm with the sediment inoculum and 100 ppm with the sludge inoculum(3). Another screening study that employed an activated sludge inoculum reported 100% degradation in 6 and 12 days when the concentration was 20 mg/L and 135 mg/L, respectively(4). Other screening studies give similar results and dimethylamine is confirmed to be biodegradable according to the standard test of the Japanese Ministry of Industry and Trade (MITI) that employs a mixed inoculum obtained from freshwater, soil, and sludge(5-7). In a laboratory activated sludge unit, dimethylamine was completely removed from inflows of up to 135 mg/L with retention times of 4 hr indicating that it should be readily degraded in biological treatment plants(4). When 250 ppm dimethylamine was added to a fine sand loam and sandy soil amended with sewage and nitrite-N, 50% degradation occurred in 2 days in the sand loam, while 20% degradation occurred in the sandy soil(8). N-nitrosodimethylamine was formed in the degradation(8). 50 to >90% degradation occurred in four silt loam or loam soils within 14 days(9).
12.3 Bioaccumulative potentialAn estimated BCF of 3 was calculated in fish for dimethylamine(SRC), using a log Kow of -0.38(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 soilThe adsorption isotherm for dimethylamine in 5 soils was linear and resulted in a mean Koc of 434.9(1). A Koc value of 508 was reported for dimethylamine in lake sediment(2). According to a classification scheme(3), this Koc data suggests that dimethylamine is expected to have moderate mobility 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.
