12.2 Persistence and degradability
Degradation of chlortoluron proceeds through the cleavage of the C-N bond as demonstrated using both soil and microbial culture studies(1). Chlortoluron had a half-life in soil of 4-6 weeks(2). The only metabolite identified in this study was monomethyl chlortoluron(2). A half-life of between 6-18 weeks was reported for chlortoluron(3). In biometer experiments, half-lives of 93 days and 40 days were measured for chlortoluron in a silty sand and silty loam soil, respectively(4). However, the disappearance of this compound in an outdoor lysimeter experiment was slower in silty loam (49 days, fallow land; 38 days, barley field) than in silty sand(52 days, fallow land; 14 days, barley field)(4). The main metabolite of chlortoluron degradation was N-dimethylated chlortoluron(4). Chlortoluron, applied as either a suspendible concentrate or wettable powder, had a calculated half-life of 96 days for both conditions in one soil (pH 5.1; organic carbon 4.1%; silt 16%; water holding capacity 27%); a second soil (pH 7.0; organic carbon 1.6%; silt 11% water holding capacity 16.6%) had calculated half-lives of 82 and 84 days for a suspendible concentrate and wettable powder, respectively(5).
12.3 Bioaccumulative potential
An estimated BCF value of 40 was calculated for chlortoluron(SRC), using an experimental log Kow of 2.41(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme, this BCF value suggests that bioconcentration in aquatic organisms is moderate, not high(3). Winter wheat grown in soil containing 4.7 mg chlortoluron/kg dry soil had bioconcentration factors of 21 and 22 for root material and for shoots, respectively (bioconcentration factor is the concentration of 14C from the chlortoluron in the plant versus the soil)(4).
12.4 Mobility in soil
An average organic matter-water distribution of 60 was measured for seven soils (organic matter range 1.09-5.92%; pH range 5.9-7.5)(1). Seventeen soils from Australia had a range of organic matter-water distribution values for this compound from 25-85, giving Koc values ranging from 1-3467 (organic matter range 0.19-6.62; pH range 4.8-8.4)(2). Leaching was studied following field application of chlortoluron to a sandy soil; after 10 cm of rain had fallen, >2 mg/kg, 1 mg/kg, 0.5 mg/kg, and a trace remained in the 0-2.5, 2.5-5, 5-7.5, and 7.5-10 cm depth, respectively(2). Chlortoluron has measured Koc values ranging from 146-346 for eight Czechoslovakian soils (mean=228), with higher values corresponding to soils with a greater content of organic matter(3). Koc values of 271 and 419 were measured for a loamy sand and a mucky peat soil, respectively, at 25°C(4). According to a recommended classification scheme(5), these estimated Koc values suggest that chlortoluron has moderate mobility in soil(SRC). Adsorption of chlortoluron corresponds to an L-isotherm indicating that as the solution concentration increases, there is a decrease in site availability(6). Chlortoluron, applied at a rate of 2.0 kg/ha to sandy soil monoliths containers, had a measured Koc of 160 and 113 in the A and B horizons, respectively(7). The addition of liquid manure, increasing the organic carbon content, resulted in reduced mobility(7).

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.
