Description of key information
Toxicity to soil macroorganisms except arthropods: Key study: The median lethal concentration (LC50) after 48 hours, for zinc acetate was 13 µg/cm2 (study performed due to method described by OECD 207 guideline).
Key value for chemical safety assessment
Additional information
Key study: Experimental results: study performed due to method described by OECD 207 guideline.
The earthworm Acute Toxicity Test for zinc acetate was performed with Eisenia fetida. As initial toxicity screening, the paper contact test was used. At least five fresh aqueous test substance dilutions with concentrations from 0% to 100% of mortality were tested. Ten o more replicates for each concentration were performed. Controls with everything except test substance were included in the assay. The test was performed without a reference substance.
The median lethal concentration (LC50) after 48 hours, for zinc acetate was 13 µg/cm2.
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.
