Description of key information
The LC50 (14d) for the test material to earthworms (Eisenia foetida) based on nominal test concentrations was > 1000 mg/kg soil dw. The NOEC was given as 1000 mg/kg soil dw (OECD 207).
Additional information
Short-term toxicity to terrestrial invertebrates
The key study was performed to assess the acute toxicity of the test material to the earthworm (Eisenia foetida) in an artificial soil. The method followed that described on the OECD Guidelines for testing of Chemicals (1984) No 207, and EEC Commission Directive 87/302/EEC.
Following a preliminary range-finding study, 60 earthworms were exposed (6 replicates of 10 worms) to a single concentration of 1000 mg/kg of soil for a period of 14 days. The number of mortalities were determined after 7 and 14 days exposure. A positive control study using chloroacetamide, conducted approximately every 6 months, is reported for reference purposes.
The LC50 (14 d) for the test material to earthworms (Eisenia foetida) based on nominal test concentrations was greater than 1000 mg/kg soil dw. The NOEC was given as 1000 mg/kg soil dw.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
