Canadian Water Quality Guidelines For Captan

Of information obtained from a literature review on the uses, fate, and effects of captan on raw water for drinking water supply, freshwater aquatic life, agricultural uses, recreational water quality and aesthetics, and industrial water supplies. Water quality guidelines for the production of specific water uses are recommended.

Updates to Canadian water quality guidelines, for tricholoroethylene, polychlorinated biphenols (PCBs), chlorinated ethanes (EDC, TCA, TECA), metolachlor, simazine, and captan include their effects on raw water for drinking, recreation, freshwater and marine aquatic life; agricultural and industrial uses; uses and production; sources and pathways; environmental concentrations; and forms and fate. In addition, methods of development for guidelines include descriptions of data requirements, evaluation of toxicological data, and methods of derivation from a chronic or an acute study.

Pesticde use in agriculture and non-agriculture settings has increased dramatically over the last several decades. Concern about adverse effects on the environment and human health has spurred an enormous amount of research into their environmental behavior and fate. Pesticides in Surface Waters presents a comprehensive summary of this research.

Water quality guidelines and objectives are used by Canadian provincial, territorial, and federal agencies in their efforts to assess water quality problems and to manage competing uses of water resources.The guidelines in this document contain recommendations for chemical, physical, radiological, and biological parameters necessary to protect and enhance designated uses of water (drinking water supply, recreational water quality and aesthetics, freshwater aquatic life, agricultural uses, and industrial supplies). The guidelines apply only to inland surface waters and groundwaters. The rationale for each parameter is included to assist in the development of water quality objectives to suit local water conditions. Parameter-specific background information and a glossary are included.
