摘要：Lakes and other waterways, and the biota in those waterways, receiving their mercury burden primarily via atmospheric deposition can be expected to exhibit responses to changes in deposition over an extended time period. A projected control strategy for power plant emissions of mercury was imposed on modeled U.S. plants, while international emissions were modeled for two Chinese emission scenarios: a “business-as-usual” scenario and an “expedited controls” scenario. Levels of mercury in fish were simulated in a New England lake located close to a large U.S. power plant. Results indicated that fish responses to mercury emissions changes were spread over several years, and that even severe reductions in U.S. emissions were masked by non-U.S. emissions growth.
