Additional information

Toxicity to soil macroorganisms except arthropods:

The NOEC for mortality and body weight on Day 28 was 1000 mg a.i./kg dry soil.  The NOEC for the number of juvenile worms on Day 56 was 1000 mg a.i./kg dry soil.

Toxicity to terrestrial plants:

In an OECD 208study, conducted according to GLP, there were no statistically significant effects on germination or survival in any plant species at any treatment rate. Germination and survival in the water control and solvent control was 100% for all species. The EC50 values for germination and survival were estimated to be >1000 mg a.i./kg dry soil for all plant species. The NOEC values for effects on germination and survival were 1000 mg a.i./kg dry soil for all plant species.

 

Toxicity to terrestrial arthropods:

A long term study is available for appropriate terrestrial organisms. This endpoint is waived.

 

Toxicity to soil microorganisms:

In an OECD216study, conducted according to GLP,the long-term effects of the test item on nitrogen transformation activity of the soil microorganisms was investigatedand the EC50 was determined to be greater than 1000 mg/kg dry weight soil. The No Observed Effect Concentrations (NOEC) was determined to be 32 mg/kg dry weight soil. 

 

In an OECD 217 study, conducted according to GLP, no significant adverse effects on the carbon transformation activity of soil microorganisms were observed following exposure to the test material at concentrations up to and including 1000 mg/kg dry weight soil following the 28-day exposure period and the test item therefore is considered to have no long-term effect on carbon transformation in soil. The NOEC for carbon transformation was determined to be 1000 mg/kg dry weight soil.
