Modeling mercury cycling and accumulation in aquatic biota across the Attawapiskat drainage basin; implications for subsistence fisheries and the Ring of Fire development in the Far North of Ontario.

Gretchen Lescord, Laurentian University (Ph.D. Student), is modeling Hg accumulation throughout the Attawapiskat Watershed, sampling lakes and rivers across the Boreal Shield and into the Hudson Plains. She is utilizing the large and diverse nature of this watershed to better understand how physical, environmental, and chemical gradients affect Hg concentrations in water, invertebrates, and fish. Her sampling includes several lakes surrounding the mineral-rich area known as the “Ring of Fire,” where extensive mining development is expected over the next decade.
