Comparing metal toxicity among Daphnia magna clones: an approach using concentration-time-response surfaces.

Abstract excerpt

This study investigates the use of concentration-time-response surfaces as a tool to predict potential long-term effects of metals to Daphnia magna, using mortality as an endpoint. Specifically, concentration-time-response surfaces were determined for four D. magna clones exposed to four metals (Cd, Zn, Cu or U) in moderate-hard or hard synthetic freshwater for 24-96 h. Mortality data were log(e) transformed into...
