Metal concentrations were measured in the muscle and liver tissue of fish captured in 54 British Columbia lakes that were considered to be relatively unaffected by human-caused pollution. The metals tested for were Al, As, Ba, Be, Ca, Cd, Cu, Fe, Hg, Mn, Ni, P, Pb and Zn. Mean concentrations were calculated by species, tissue type, lake, biogeoclimatic zone and tectonic region. Mercury was the only metal to show evidence of bioaccumulation, although the results may be suspect because of sampling techniques. The highest levels of Pb in muscle tissue were found in mountain whitefish (0.46 Mg/g wet-weight) and were below the upper limit recommended for human consumption (0.8 Mg/g wet-weight). Cutthroat trout had the highest level of Hg in muscle tissue (0.29 Mg/g wet-weight), and this too was below the upper limit recommended for human consumption (0.5 Mg/g wet-weight). The mean values reported for each species may be useful as indicators of metal concentrations in tissue of fish from lakes that are considered t
