Monitoring stations were operated at Roush Lake near Huntington, Clifty Falls State Park near Madison, Fort Harrison State Park near Indianapolis, Monroe County Regional Airport near Bloomington, and Indiana Dunes National Lakeshore near Porter. At these monitoring stations, precipitation amounts were measured continuously and weekly samples were collected for analysis of mercury by methods achieving detection limits as low as 0.05 ng/L (nanograms per liter). Wet deposition was computed as the product of mercury concentration and precipitation. The data were analyzed for seasonal patterns, temporal trends, and geographic differences.MercuryEnvironmental aspectsIndianaAirPollutionIndianaAtmospheric depositionIndianaMercuryEnvironmental aspectsAirPollutionAtmospheric depositionRisch Martin R329522Fowler Kathleen K1390599Indiana.Department of Environmental Management.Geological Survey (U.S.)EJBEJBGPOBOOK9910698169303321Mercury in precipitation in Indiana, January 2004-December 20053452119UNINA
