Alarming Levels of Mercury Contamination Found Across Western North America
An international team of scientists led by the U.S Geological Survey (USGS) released a comprehensive report last week showing widespread mercury contamination across western North America.
The report, based on decades of mercury data and research, found alarming levels of mercury and methylmercury in the forests, fishes, wildlife, plants and waterways of America’s western landscapes. The USGS study provides the first integrated analysis of where mercury occurs in western North America, how it moves through the environment, and the processes that influence its movement and transfer to aquatic and ultimately, the human food chain. Fish are indicators of methylmercury contamination because they are an important link in the food chain for both wildlife and humans.U.S. Forest Service
