Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- 14-day LC50 (earthworms) > 1000 mg (a.i. as total solids)/kg dry weight soil.
14-day NOEC (earthworms) > 1000 mg (a.i.as total solids)/kg dry weight soil. - Executive summary:
The acute toxicity of the test substance to earthworms, Eisenia fetida, was estimated in a 14-day soil exposure laboratory study conducted under OECD Guideline 207 in artificial soil. Based on the results of a range-finding test, a Limit Test was conducted. The 14-day LC50 and NOEC were determined to be greater than 1000 mg (a.i. based on total solids)/kg dry weight soil.
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.
