Metal and Metalloid Contaminants in Water, Sediments, Fish, and Mammals of Kanuti National Wildlife Refuge, Alaska, 1985-1990

摘要

This study was conducted by U.S. Fish and Wildlife Service biologists from 1985 through 1990. The study goals were to monitor water quality as well as concentrations of metals and metalloids in water, stream sediments, fish, and mammals; evaluate existing effects of heavy metal contamination and water quality degradation on refuge resources due to placer mining; and make recommendations for collection of additional baseline data to protect water quality, conserve fish and wildlife populations and their habitats, and to protect subsistence use, consistent with refuge goals. Water samples were collected from 32 sites; 16 sites on Kanuti National Wildlife Refuge and 16 sites upstream from it.
