Impacts of Land Use on Mercury in Urban Stormwater Runoff

Mercury is a pollutant that poses a serious threat to human and   ecosystem health. It is present in the atmosphere worldwide in   measurable concentrations, primarily as a result of human activities   such as coal burning and waste incineration. The primary pathway of   human exposure to mercury is through the consumption of contaminated   fish, therefore, understanding the process of mercury transport from   atmospheric to aquatic systems is important to the protection of   human health.     The aim of this study is to investigate the impacts of different   types of urban land use and land cover on mercury pollution in   stormwater runoff, and to determine if stormwater management   measures, such as green roofs, retention ponds, and rainwater   gardens, have a positive or negative effect on the problem. This   issue will be investigated in areas close to mercury-emitting point   sources as well as in areas that are not near any point sources.   Samples will be collected in the city of Milwaukee, WI, at points   where overland flow or storm sewer effluent is discharged into a   stream or lake.     (Wisconsin); (land use); (mercury); (toxic metal); (toxic metals);   (chemicals of concern); (chemical of concern); (human health);   (stormwater); (wastewater)
