Mapping pollution across the globe

Mapping pollution across the globe

Using recent satellite observations, ground monitoring and computational modeling, researchers at the McKelvey School of Engineering at Washington University in St. Louis have released a survey of global pollution rates. There are a couple of surprises, for worse, but also, for better.

Pollutants in some urban areas increase Parkinson’s disease risk

High levels of manganese and copper pollution in urban areas are linked to increased risk of Parkinson’s disease, according to a large-scale analysis of urban pollution and Parkinson’s incidence in the United States. Scientists at Washington University School of Medicine in St. Louis found that people living in areas with higher levels of manganese pollution had a 78 percent greater risk of Parkinson’s disease than those living in areas free of such pollution.

Washington University, two industries, team to clean up mercury emissions

Pratim Biswas, Ph.D., chair of WUSTL’s energy, environmental and chemical engineering department, heads a project involving Washington University, Chrysler LLC and Ameren Corporation to test a mercury removal process in a full-scale power plant.Washington University in St. Louis is partnering with Chrysler LLC and a major Midwest utility company in a project to determine if paint solid residues from automobile manufacturing can reduce emissions of mercury from electric power plants. The project is based upon the technical expertise of Pratim Biswas, Ph.D., Stifel & Quinette Jens Professor of Environmental Engineering Science who has demonstrated the effectiveness of titanium dioxide in controlling mercury in lab and recent field studies. He heads the project that will test a mercury removal process in a full-scale power plant.

The sustainable rivers program will be held April 22 from 10:30 a.m. to 5 p.m. and will feature Washington University faculty Charles Buescher, professor of environmental engineering, Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences and William Lowry, Ph.D., professor of political science in Arts & Sciences. The colloquium will provide a background history of the rivers in our region and their various uses in transportation, agriculture, power production, recreation and public water supply.
