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...

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. Total mercury concentrations in surface sediments transect samples, core samples, tributary samples, and representative food web species were measured...
