Acute toxicity of equitoxic binary mixtures of some metals, surfactants and pesticides to the freshwater amphipod gammarus italicus goedm

Abstract

Acute toxicity of two metals, three surface active agents and two organophosphorous insecticides and their equitoxic binary mixtures to the freshwater amphipod Gammarus italicus Goedm. was studied in static conditions. The results of 21 experiments, each testing the joint toxicity of two substances, demonstrate only simple additivity (in 9 experiments) and less than additivity (in 12 experiments) and no synergistic effects.
