The 48-h EC50 of 0.24 mg/L in Daphnia magna is used in the assessment.
Two short-term toxicity studies with Daphnia
magna are available for zinc diethyldithiocarbamate. A non-GLP, OECD
202 guideline study is available (van Leeuwen et al., 1985a; van
Leeuwen, 1986). The test is semi-static without analytical monitoring.
The 48-h EC50 value is 0.24 mg/L in Daphnia magna.
Another study is a static
GLP-compliant, EPA-660/3-75-009 guideline study without analytical
monitoring (Analytical Bio-Chemistry Laboratories, Inc., 1983d). The
48-h EC50 value in Daphnia magna is 0.44 mg/L.
The 48-h EC50 of 0.24 mg/L is the most
critical value and is therefore used for assessment.
