Toxicity of Metal Cations for Daphnia

Abstract

A statistically significant relationship was established between the median lethal concentrations of metal cations for daphnia and the maximum permissible concentrations of metals for fishery water bodies. A new eco-toxicological approach to the integrated assessment of the surface water contamination by metals, based on the combined risk concept, was developed. This approach can be used for assessment of the metal contamination of water bodies in various climatic zones and for analysis of the inter- and intra-annual trends of water body contamination.
