RT Journal Article ID 4505d98121d8b9d1 A1 Scherban', E. P. T1 Study of the Algerian superphosphate toxicity for Daphnia magna and Ceriodaphnia affinis JF Hydrobiological Journal JO HYD YR 2001 FD 2001-10-01 VO 37 IS 5 OP 8 AB Vital, lethal and median concentrations of Algerian superphosphate for Daphnia magna and Ceriodaphnia affinis were determined in acute tests. Both chronic lethal (500 mg/L) and sublethal (250 mg/L) concentrations were detected in chronic experiments. At 25, 50 and 100 mg/L superphosphate concentrations demonstrated the stimulating effect on the rate of embryonic and postembryonic development, as well as, only particularly, on fertility of the crustaceans studied.
