title: [The effect of humic substances on the toxicity of copper and zinc for Daphnia magna].
abstract: The results of laboratory experiments of humic matter influence on toxic resistance of Daphnia magna to zinc and copper using water samples from a few Karelia water bodies are presented. The increasing of humic matter content in water samples has been shown to promote the binding of a part of metals in organic complexes that leads to decrease of their toxicity for hydrobionts.
