The potential health effects of environmental contaminants in traditional food has become a concern among northern communities because of the presence of environmental contaminants in the Arctic ecosystem.
Exposure assessments are needed but they require comprehensive dietary information and contaminant data.
Over the last 10 years, there has been considerable effort to monitor the level of contaminants in fish and wildlife collected from different regions in northern and Arctic Canada.
The development ofa database and its application for dietary contaminant exposure assessment are described.
We conducted an extensive literature review on levels of environmental contaminants in northern and Arctic Canada.
The ranges of levels of four contaminants of major concern (chlordane, mercury, polychlorinated biphenyls and toxaphene) in 81 species of marine mammals, terrestrial mammals, birds, fish and plants are summarized.
These data represent 69% of the 117 species of fish, wildlife and plants mentioned in our dietary interviews conducted in the northern communities.
A significant percentage of the foods had contaminant levels exceeding the guidelines used by Health Canada for market food consumed by the'southern'populations.
Mathematic modelling of the distributions of the data showed that contaminant levels in most food groups are log-normally distributed and have a typical coefficient of variation of about 100%. (...)
