Description High polychlorinated biphenyl (PCB) concentrations in Spokane River reservoir sediments are related to the type of particulate matter found in the sediment. Microscopical examination showed that the bulk of the organic matter was wood and plant material in varying states of decay. Also present in significant amounts were wood charcoal and partially carbonized plant material. The sediments were separated into charcoal, wood and silt/clay (<38 um) fractions and analyzed for PCBs.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
