Role of food and clay particles in toxicity of copper and diazinon using Daphnia magna

Toxicity changes in copper and diazinon were investigated in the presence of food, clay, and their mixture by using Daphnia magna. In sorption equilibrium experiments, copper was significantly attracted (>34% sorbed) to food, clay, and food–clay mixture due to their negative zeta potential, while...

Zusammenfassung:	Toxicity changes in copper and diazinon were investigated in the presence of food, clay, and their mixture by using Daphnia magna. In sorption equilibrium experiments, copper was significantly attracted (>34% sorbed) to food, clay, and food–clay mixture due to their negative zeta potential, while diazinon was less sorbed (
