Water Quality Criteria for Cyanide in the Similkameen River, British Columbia

by L. John Zeman, Environment Canada, Canada,

Document Type: Proceeding Paper

Part of: Irrigation and Drainage


The toxicological and environmental significance of the major cyanide compounds is discussed. Data from earlier bioassays studies of cyanide are summarised and the ranges of median lethal and sublethal tolerance limits for freshwater fish are indicated. Rainbow trout is the particular sport fish species to be protected in this river system. Actual concentrations of cyanide collected during the period from 1984 to 1988, were compared with the Canadian Water Quality Guidelines, the British Columbia Ministry of Environment Water Quality Objectives, and the United States Environmental Protection Agency Water Quality Criteria.
