Description of key information
In an earthworm reproduction and growth study with 400160 the No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be higher than or equal 1000 mg test item/kg soil, i.e. the highest concentration tested.
Key value for chemical safety assessment
Additional information
The effects on reproduction and growth of earthworms (Eisenia fetida) in artificial soil were determined with test item 400160 with an OECD 222 study.
All study validity criteria were met. No mortality was observed in any treatment group. The body weight changes of the earthworms after 4 weeks exposure to 400160 were not statistically significantly different compared to the control up to and including the highest test concentration of 1000 mg test item/kg soil (Williams t-test, α = 0.05, two-sided). The reproduction rates were not statistically significantly different compared to the control up to and including the highest test concentration of 1000 mg test item/kg soil (Dunnetts t-test, α = 0.05, one-sided smaller). No behavioural abnormalities were observed in any of the treatment groups. The feeding activity in all the treated groups was comparable to the control.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
