Description of key information

The 14-Day LC50 (mortality) for the test material to earthworms (Eisenia foetida) based on nominal test concentrations was greater than 1000 mg/kg soil. The No Observed Effect Concentration was 1000 mg/kg soil.

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
1 000 mg/kg soil dw

Additional information

According to OECD Guidelines for the Testing of Chemicals, No. 207 Earthworm, Acute Toxicity Test, the acute toxicity of the test substance to earthworms (Eisenia foetida) was determined in a 14 day test.

The test was conducted as a limit test with a nominal concentration of 1000 mg/kg soil.

The 14-Day LC50 (mortality) for the test material to earthworms (Eisenia foetida) based on nominal test concentrations was greater than 1000 mg/kg soil. The No Observed Effect Concentration was 1000 mg/kg soil.
