Description of key information
Effects of the test item on mortality, biomass and the reproductive potential of the earthworm species Eisenia fetida(Annelida, Lumbricidae) were determined according to the Guideline OECD 222 in year 2013. Under the conditions of this study, the test item did not induce evident mortality, pathological symptoms orchanges of the behaviour of adult earthworms after 28 days of exposure at all tested concentrations.
Thus, the No Observed Effect Concentration (NOEC) for the test item summarizing the endpoints mortality, body weight and reproduction of Eisenia fetida fetida after 8 weeks of exposure in artificial soil was determined to be 250 mg test item/kg soil dry weight.
The LOEC was determined to be 500 mg test item/kg soil dry weight. The EC50 for reproduction was determined to be 618 mg test item/kg soil dry weight (Confidence Intervall: 468 to 885 mg test item/kg soil dry weight).
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 250 mg/kg soil dw
Additional information
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.
