Abstract

Standards for pesticide concentrations in water are based on the laboratory toxicity of the most susceptible standard test organisms (algae, crustaceans or fish). Field studies have shown that the standards for the insecticide chlorpyrifos and the herbicide atrazine will protect aquatic ecosystems at both species and community levels. This study was aimed at evaluating the chronic effects of the standards for chlorpyrifos and atrazine in experimental freshwater model ecosystems. It is concluded that standards based on acute exposure are not simply transferable to chronic exposure.
