Additional information

Chronic effects of 2 -mercaptoethanol were investigated in a chronic GLP test accordingly to OECD guideline 211 using Daphnia magna as test organisms. After 21 days, mortality was the most sensitive endpoint in this study resulting ina NOEC >0.0632 mg/l and a LOEC of 0.1264mg/l related to the corrected nminal concentrations. No significant reproduction or any other additional significant adverse effects or abnormal behaviour were observed in any of the test treatments.
