Western Wildfires Causing Mercury Pollution
Mercury Pollution from Wildfires
As thousands of acres continue to burn across the western United States, scientists from The National Center for Atmospheric Research and the University of Washington are flying over the wildfires to measure mercury emissions in their smoke.
During a wildfire, mercury stored in the foliage and ground litter is released and carried into the atmosphere, says NCAR scientist Hans Friedli. He and Lawrence Radke are conducting research flights over wildfires and prescribed burns. Scientists are trying to understand the global sources of atmospheric mercury, as well as how much of the dangerous substance ends up in the food chain.
