Description of key information

LC50 (14 d) > 1000 mg test item/kg dry weight soil (Eisenia fetida, OECD 207)

NOEC (14 d) ≥ 1000 mg test item/kg dry weight soil (Eisenia fetida, OECD 207)

Key value for chemical safety assessment

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

Additional information

One experimental study is available investigating the toxicological effects of the test item to earthworms (M-075743-01-2). The study was performed according to OECD guideline 207 under GLP conditions. Adult Eisenia fetida andrei (4 x 10 animals per concentration, the overall average weight was 0.33 g) were exposed for 14 days in an artificial soil to the nominal concentration of 1000 mg test item/kg dry weight soil. The artificial soil comprised 10% peat. No morphological and behavioral effects were observed. Related to weight alterations and symptoms, the no-observed-effect-concentration (NOEC) was ≥ 1000 mg test item/kg dry weight soil, the lowest-observed-effect-concentration (LOEC) > 1000 mg test item/kg dry weight soil. No mortality was recorded resulting in a LC50 (14 d) of > 1000 mg test item/kg dry weight soil.
