Selenoneine Protection Against Methylmercury Toxicity: A Potential Benefit of Beluga Maktaaq consumption for Inuit health

Inuit are exposed to a wide range of environmental contaminants through their traditional diet, which includes significant amounts of fish and sea mammals. During the past 25 years, our team has monitored the exposure of Nunavimmiut to persistent organic pollutants (POPs) and metals, starting with the Santé Québec Inuit Health Survey in 1992, which was followed by the Qanuippitaa 2004 Health Survey. From 1992 to 2004, for most legacy POPs, a significant decreasing trend was confirmed in environmental components, and wildlife and circumpolar Inuit exposure data. Despite a decreasing trend mostly due to reduced consumption of country foods, mercury (Hg) and lead (Pb) exposures remain topical issues, particularly among childbearing and pregnant women in Nunavik. In addition, each year, new chemicals are introduced in the market. These “New POPs and Contaminants of Emerging Concern (CECs)” now reach the Arctic food chain and very little is known about their concentrations and temporal and regional trends in Inuit. In this new two-year project, we aim to provide current data on exposure to food-chain contaminants in a representative sample of the Inuit population of Nunavik within the framework of the Qanuilirpitaa Nunavik Inuit Health Survey, which took place during the fall of 2017 in the 14 communities of Nunavik. This project will allow Canada to maintain its role at the forefront of international biomonitoring efforts on long-range environmental contaminants exposure among circumpolar populations and contribute to understanding the risks and benefits of country foods consumption in the Arctic.
