In addition to killing insects and weeds, pesticides can be toxic to the environment and harmful to human health. A new project led by Associate Professor Dong Wang and Huichun Zhang, Frank H. Neff Professor of Civil Engineering at Case Western Reserve University, will help scientists mitigate the environmental and ecological risks of pollutants such as pesticides and develop remediation strategies for cleaner water, soil, and air. The researchers have received a three-year, $402,773 National Science Foundation (NSF) grant for their project, "Machine Learning Modeling for the Reactivity of Organic Contaminants in Engineered and Natural Environments."
