Since 1966, the Fish and Wildlife Branch has been submitting samples from a variety of plant and animal species for pesticide analysis. Analyses have been carried out at the British Columbia Department of Agriculture Pesticide Laboratory in Vancouver. Results are presented by species, grouped by geographic area within each species listing. The results show that contamination by chlorinated hydrocarbons is widespread throughout the province. In addition, the presence of polychlorinated biphenyls (PCBs) is now being demonstrated in many species. This report is intended to provide a history of environmental pollution in British Columbia and an indication of present contamination levels.
