Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.

Persistence and degradability
AEROBIC: Sulfometuron readily biodegrades in aerobic soil. The half-life was reported to be 12-25 days (2-4 weeks) in various soil conditions(1,2). In native sediments at neutral pH, microbial degradation of sulfometuron methyl was prevalent. Pseudo-first-order dissipation rate constants between 1.27X10-2 days-1 and 3.95X10-2 days-1 were determined from a stream and pond near Athens, Georgia(3), corresponding to half-lives of 54 and 17 days, respectively(SRC). (14C)Sulfometuron methyl degraded in aerobic soils under laboratory and field conditions at a rate dependent upon soil pH and moisture content. Saccharin was the major degradation product under sterile conditions, but in the presence of a viable soil microbial population, metabolism of the phenyl ring of [phenyl-14C]sulfometuron methyl to 14-CO2 was observed(4).
Bioaccumulative potential
An estimated BCF of 99 was calculated for sulfometuron methyl using an estimated log Kow of 1.2(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). (14C)Sulfometuron methyl has a low partition ratio (0.31) between n-octanol and 0.01 M phosphate buffer, pH 7.0. It does not accumulate in fish tissue when fish are exposed to 0.01 ppm or 1.0 ppm (14C)-sulfometuron methyl in their environment(4).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of sulfometuron methyl can be estimated to be 107(SRC). According to a classification scheme(2), this estimated Koc value suggests that sulfometuron methyl is expected to have high mobility in soil. The pKa of sulfometuron methyl, a weak acid(3), is 5.2(4), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Sulfomethuron methyl's potential to leach in alkaline soils is higher than in low pH soils(6). Sulfometuron methyl (or its degradation products) was more mobile in soils with pH 7 or greater than in soils with pH near or below the sulforneturon methyl pKa. This increased mobility was attributed to ionization of sulfometuron methyl and hence increased water solubility(7). (14-C)Sulfometuron methyl was mobile on soils when tested using soil thin-layer plates and soil columns; this mobility agreed reasonably well with Freundlich soil isotherm constants(8).

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.
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.
