Fraser River Action Plan 3rd Research Workshop
• Total PCB levels were highest in lower Fraser Valley;
• Total chlorophenolics levels were highest at Marguerite, downstream of Quesnel; and,
• The PAH metabolite pattern varied between the two species; levels were high at Marguerite.
A more thorough review and analysis of the data must be conducted before conclusions can be presented.
Contaminants information gaps included:
• Additional contaminants we should be measuring (e.g., non-ionic surfactants);
• Sources of contaminants;
• Non-toxic levels in fish (i.e., guidelines); and,
• Migratory patterns and life histories of fish.
