Fish and wildlife were randomly sampled in Utah from pre-selected x areas and analyzed for levels of total mercury, dieldrin, DDT, and DDE. Levels were well within consumptive tolerance or guideline limits except for mercury levels of fish in Willard Bay Reservoir. PCB's were also identified in a large proportion of samples. None of the chukars, 6 percent of the pheasants, 4 percent of the waterfowl, and none of the fish sampled, excluding Willard Bay Reservoir, were above the 0.5 ppm guideline level for mercury established by the Food and Drug Administration. Seventy-seven percent of the fish sampled from Willard Bay Reservoir were above the 0.5 ppm guideline level. Only one duck (2 percent) was above the maximum permissible concentration for dieldrin. All of the chukars, pheasants, other waterfowl, and fish were well below human consumptive tolerance limits for dieldrin and DDT + DDE. It is recommended that studies be initiated to more closely define possible sources of mercury and the health hazard involved in consumption of these fish.
