Continuous Monitoring of Pollution in the Nation’s Precipitation with a Focus on Conditions in Indiana and the Great Lakes
Aired: July 10, 2013 from noon to 1pm Eastern
Since 1978, the National Atmospheric Deposition Program (NADP) has tracked the status and changes in the many different chemical compounds within precipitation across the continent. The NADP monitors the removal of pollutants from the atmosphere; but more importantly, it monitors the addition of chemical compounds into the Biosphere and ecosystems of North America. Join us to learn about trends in mercury and nitrogen deposition
