Exposure to Food Chain Contaminants in Nunavik: Biomonitoring in Adult and Youth Cohorts of the Qanuilirpitaa Survey

The purpose is to update data on exposure to food-chain contaminants among Nunavimmiut. This will be achieved in the framework of the Qanuilirpitaa Nunavik Inuit Health Survey, which comprises an adult cohort of adults - 31 years and older - and youths between 16 and 30 years of age (1329 participants). Therefore we will: 1. Measure through biomonitoring Nunavimmiuts exposure to toxic metals [mercury (Hg), lead (Pb), and cadmium (Cd)] and legacy persistent organic pollutants (POPs), new POPS and contaminants of emerging concerns (CECs), as well as other new CECs currently only investigated as part of environmental monitoring programs in the Arctic; 2. Evaluate the nutritional status of Nunavimmiut (omega-3 polyunsaturated fatty acids (PUFAs), total selenium (Se) and selenoneine, hemoglobin and iron status, and manganese (Mn); 3. Account for country and store-bought food consumption of Qanuilirpitaa participants, food security, socio-demographic status, lifestyle habits and anthropometric characteristics in explaining biomonitoring data.
