12.1 Toxicity

  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill); Conditions: freshwater, static; Concentration: >12500 ug/L for 96 hr /92% purity
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age <24 hr); Conditions: freshwater, static; Concentration: >1000 ppm for 48 hr; Effect: intoxication immobilization /75% purity
  • Toxicity to algae: EC50; Species: Pseudokirchneriella subcapitata (Green algae); Conditions: freshwater, static; Concentration: 4.6 ug/L for 5 days (95% confidence interval: 2.6-8.2 ug/L); Effect: population abundance /99.1% purity
  • Toxicity to microorganisms: no data available

12.2 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).

12.3 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).

12.4 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).

12.5 Other adverse effects

no data available

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.
