Description of key information
An OECD TG 222 guideline study in compliance with GLP with earthworm (Eisenia fetida) is available for the test substance. Earthworms were exposed to nominal concentrations of 5.00, 9.00, 16.2, 29.2, 52.5, 94.5, 170 and 306 mg test item/kg soil dry weight in a geometric factor of 1.8 along with a control group (without test item) and a solvent control (acetone) for 56 days test period. Based on the results the effect parameters were expressed on the basis of nominal concentrations. Besides the highest concentration tested no mortality was observed in the control and other concentrations. The EC10 reproduction was determined to be 28.4 mg test item/kg soil dry weight with the lower and upper 95 %-confidence limits of 7.82 and 43.8 mg test item/kg soil dry weight. The study met the acceptability criteria prescribed by the protocol and was considered valid.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
