Mercury is a global contaminant that accumulates in organisms, including humans, and can result in many health problems. Eating fish is the primary route by which humans are exposed to mercury, and mercury levels tend to be high in northern regions due to global atmospheric circulation patterns and atmospheric deposition of mercury. Our aim is to understand what the key drivers of fish mercury concentrations are in traditional fishing lakes in the Dehcho region, and how/if these drivers vary predictably among lakes. Furthermore, the water quality, sediment quality, fish tissue and fish health results have informed consumption guidelines of the fish in the waterbodies being studied, as fish are a valuable traditional food resource to First Nations.
