New Air Pollution Impacts Report

Harvard Forest Science & Policy Integration Project Director, Kathy Fallon Lambert, partnered with the Ecological Society of America to co-author a new Issues in Ecology report, "Setting Limits: Using Air Pollution Thresholds to Protect and Restore U.S. Ecosystems" (available free as a PDF). The report provides an overview of the on-going impacts of atmospheric deposition of sulfur, nitrogen and mercury in the U.S. It presents a series of ecological thresholds for evaluating air pollution impacts on terrestrial and aquatic ecosystems, and it proposes science-based strategies for using deposition-based limits to reduce acid rain, nitrogen enrichment, and the accumulation of mercury in the environment.
