Climate – Mercury Interactions

Reed Harris Environment Ltd. is currently investigating potential links between climate change and mercury cycling in the environment. These studies, which involve simulation modeling, laboratory experiments and analysis of existing data, are being done in collaboration with the Smithsonian Institution. The work is supported by Environment Canada and the Great Lakes Atmospheric Deposition Program (Great Lakes Commission).

Climate-related factors that will be studied for potential influences on mercury include temperature, hydrology, carbon and mercury export from terrestrial systems, in-lake water quality and trophic factors and atmospheric mercury deposition. Study results will allow policy-makers to better assess the effects of climate change on mercury risks to humans and wildlife, and to target the most important interactions between climate change and mercury for further monitoring and study.
