摘要

Copper complexation capacity was determined in a range of sewage treatment works final effluents and receiving waters, upstream and downstream of the discharge point. Forty-eight-hour immobilization tests on Daphnia magna were used to assess the toxicity of copper in the effluent matrix. Complexation capacities in effluents were typically in the range 50 to 100μg Cu/L, with higher values being found in the poorer-quality effluents with higher dissolved organic carbon(DOC) concentrations. The tolerance of Daphnia to dissolved copper concentrations was more than quadrupled in a 50/100 effluent matrix, with the increase in tolerance being related to complexation capacity.
