12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Salmo gairdneri (Rainbow trout) 3.0 mg/l/96 hr @ 12°C (95% confidence interval 2.0- 4.5 mg/l), wt 0.7 g. Static bioassay without aeration, pH 7.2-7.5, water hardness 40-50 mg/l as calcium carbonate and alkalinity of 30-35 mg/l.
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

The 3-trifluoromethyl moiety of fluometuron seems to be accessible to some extent to biochemical transformation reactions. A slight but measurable amount of radioactivity (< 5% of the dose applied) evolved as carbon dioxide during the 52 day observation period on incubation of the (14)C trifluoromethyl-labeled herbicide in soils. Oxidation of the trifluoromethyl carbon represents a minor pathway of degradation for fluometuron in the soil.

12.3 Bioaccumulative potential

An estimated BCF of 15 was calculated for fluometuron(SRC), using a log Kow of 2.42 (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. However, in a study of unicellular green algae (Chlorella fusca), a log BCF of 1.96(4) was determined for fluometuron, corresponding to a BCF of 91.2 and indicating a moderate potential for bioconcentration in algae.

12.4 Mobility in soil

Experimental Koc values for fluometuron in soil range from 29 to 173(1-6). This range of the Koc values indicate that fluometuron would have very high to moderate mobility in soil(7). Soil thin layer chromatography studies confirm that fluormeturon adsorbs weakly to moderately to soil based on experimental Rf values determined in 13 soils (organic matter 0.36-10.26%) ranging from 0.17 to 0.89(8-10). The Koc for fluometuron ranges from 29 to 200 for various soil types (including sandy and loam soils)(11). It is moderately leachable in all but very sandy soils; the Koc value range from 31 to 117 (8 soil types); Kd = 0.15 to 1.13(12). The adsorption of fluometuron increases with increases in organic content(13,14) and clay content of soil(14).

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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
