Additional information

The acute toxicity of zinc bis dimethyldithiocarbamate (CAS No. 137-30-4) to Daphnia magna was investigated by Douglas et al. (1991). This test was conducted according to OECD Guideline 202,Daphnia sp. Acute Immobilisation Test (1984) and EPA OPP 72-2 (Aquatic Invertebrate Acute Toxicity Test), under GLP conditions. After 48 hours of exposure to the test substance within a semi-static water regime, daphnids immobilisation was reported, and a EC50 of 0.048 mg a.i./L was determined.
