AEROBIC: Degradation rates of 14C-labeled acetochlor in sandy loam soils from Eastern Virginia were found to range from 8 to 15% of applied concentration over a period of 48 days(1). In sewage sludge the overall degradation rate constant and half-life were determined to be 0.0403 per hour and 17.2 hours, respectively, while in soil the overall degradation rate constant and half-life were determined to be 0.1601 per day and 4.3 days, respectively(2). Using a soil inoculum from an agricultural field of Northwestern Beijing, China (pH 8.4; 1.5% organic carbon; cation exchange capacity 84.0 mmol/100 g; 59% silt; 38% sand; 3% clay), a half-life of 4.6 days was reported following 35 days incubation; acetochlor was added at a concentration of 10 mg/kg(3). Acetochlor at a concentration of 1 mg/kg exhibited 6.7% and 23.9% mineralization after 58 and 90 days in neoluvisol and calcosol soils, respectively, under laboratory conditions. Soil characteristics were as follows: Neoluvisol - 15.4% sand; 66.0% silt; 18.6% clay; 14.80% organic carbon; pH 7.47; cation exchange capacity: 12.3 cmol/kg; water content: 16.6 cu cm/100 cu cm. Calcosol - 14.7% sand; 57.1% silt; 23.9% clay; 16.21% organic carbon; pH 8.05; cation exchange capacity: 18.6 cmol/kg; water content: 14.7 cu cm/100 cu cm. First-order degradation rate constants in neoluvisol maintained at 25 and 15 deg C were 0.14/day and 0.05/day, respectively, corresponding to half-lives of 5.1 and 14.9 days, respectively. First-order degradation rate constants in calcosol maintained at 25 and 15 deg C were 0.20/day and 0.11/day, respectively, corresponding to half-lives of 3.5 and 6.3 days, respectively(4).
An estimated BCF of 250 was calculated in fish for acetochlor(SRC), using a log Kow of 4.14(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).
The Koc of acetochlor has been reported as 98.5(1), 239(2), log 2.30 (Koc = 199)(3), and 165(4). Using a silty clay loam, a Koc of 335 was reported(5). According to a classification scheme(6), this range of Koc values suggests that acetochlor is expected to have high to moderate mobility in soil. The leaching potential of acetochlor was assessed to be marginal based on a Koc value of 165 mL/g and a half-life in soil of 12 days(4). Freundlich adsorption coefficients of 7.9 and 4.8 were reported using Chinese agricultural soils - Beijing (pH 8.4; 1.5% organic carbon; cation exchange capacity 84 mmol/100 g; 59% sand; 38% silt; 3% clay) and Hebei (pH 7.7; 0.8% organic carbon; cation exchange capacity 215.4 mmol/100 g; 73% sand; 22% silt; 5% clay)(7). Using a soil inoculum from an agricultural field of Northwestern Beijing, China (pH 8.4; 1.5% organic carbon; cation exchange capacity 84.0 mmol/100 g; 59% silt; 38% sand; 3% clay), a mean Freundlich adsorption coefficient of 4.339 L/kg was measured(8).

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.
