  • Mercury distribution in sediments and uptake into an aquatic food web at Cottage Grove Reservoir, Oregon

    Creator:
    Morgans, Donna L.
    Abstract:
    The Cottage Grove Reservoir has been impacted by a point source (Black Butte Mine), where mercury mining and processing has occurred within its watershed from the 1890's to the late 1960's.

  • Point and nonpoint source mercury pollution of Oregon Reservoirs

    Creator:
    Park, Jeong-Gue
    Abstract:
    Two Oregon reservoirs contaminated by different mercury sources were compared for mercury distribution in sediment and bioaccumulation by fish. The average mercury concentration in the sediment of Cottage Grove reservoir (0.67 ± 0.05 μg/g dry wt) was higher than for Dorena Reservoir (0.12 ± 0.01 μg/g dry wt). Sediment mercury...
