Additional information

The effect of zinc bis dimethyldithiocarbamate (CAS No. 137-30-4) on aquatic microorganisms activity was investigated by Hanstveit et al. (1999). This test was conducted according to OECD Guideline 209, Activated Sludge, Respiration Inhibition Test (1984), under GLP conditions. After 3 hours of exposure to the test substance at 20°C, respiration rate inhibition in activated sludge microorganisms was reported, resulting in a EC50 value of 19.2 mg/L.
