Project Team: B. Billeck; B. Danell; L. Lockhart;

Objective(s): To measure the history of atmospheric contaminant deposition and the current rate of supply of contaminants (Pb, Cd, Hg, DDT, PCB, HCH, toxaphene, Dioxin, PAHs, industrial soots and charcoal) to lake sediments; to measure the concentrations of organochlorine contaminants in fish tissues and various enzymes and proteins in fish tissues that are thought to be contaminant stress response indicators;

Project Description: The Researcher and team will obtain live fish for immediate field dissection and dry ice freezing of tissue samples for contaminant, enzyme and protein measurements. Large core samples of deep lake muds are sliced into thin layers in the field for radiochemical estimation of slice age and the measurements for organochlorines, PAHs, metals and other geochemical parameters.
