Cantung Mine Human Health and Ecological Risk Assessment
Principal Investigator: Perzoff, Tania
Licensed Year(s): 2018
Summary: Tetra Tech modeled the effects of food chain accumulation of metals and exposure to metals on human health and ecological receptors. Tissue sampling of small rodents (and possibly hares) will be completed to identify trophic transfer of potential soil contaminants in order to verify the model. Snap traps and pitfall traps will be set out by Tetra Tech Staff and two First Nations subcontractors....
