This project provided matching funds for the participation of a Canadian researcher in a European research project on the effect of climate change on the contaminant exposure and resulting health effects in Arctic human populations. In particular, the research used conceptual and numerical models to predict how and to what extent the exposure of human and wildlife populations in the North are likely to change as a result of the rapidly changing Arctic climate. The models and the results of simulations using these models facilitate the interpretation of time trends of contamination in air, wildlife and humans, by identifying and quantifying the confounding influence of climate change on those time trends.
