Description Gasworks Park, a 20-acre park on the north shore of Lake Union, Seattle, Washington, is the site of a retired coal gasification plant that ran for 50 years ending in 1956. The sediments adjacent to Gasworks Park are heavily contaminated with a number of toxic compounds including polycyclic aromatic hydrocarbons (PAH), heavy metals, and cyanide (Hileman et al., 1985; Yake et al., 1985). Fish residing in this urban area may be exposed to relatively high concentrations of PAH and heavy metals. To determine if fish exposed to these contaminations show abnormalities, liver, kidney, and gills from 157 fish were examined with histopathology methods. Blood was also examined.
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.
