Risk Assessment of Dietary Lead (Pb), Cadmium (Cd), and Mercury (Hg) Exposure among First Nations People in Ontario, Canada - a Total Diet Study and Probabilistic Assessment
This thesis quantified risks of lead (Pb), cadmium (Cd), and mercury (Hg) in the diet of First Nations peoples residing on-reserve in the province of Ontario, Canada. Data was obtained from the 2011-2012 First Nations Food, Nutrition, and Environment Study (FNFNES) and Health Canada to construct tot...
