要約

Paper deals with data on the effect of the herbicide “Norvel” (active component − quizalofop-p-ethyl, 50 g/L) on the quantity and quality of Ceriodaphnia affinis breed in a series of five generations. Under the herbicide concentration 0.01 mg/dm3 reproductive potential of the studied animals decreased from generation to generation and reproduction stopped at the 5th generation. Concentration 0.001 mg/dm3 was considered as inhibiting, number of progeny decreased by 29% (P > 99%). Concentration 0.0001 mg/dm3was considered as ineffective for the test-objects.
