Tracking water pollutants: Study evaluates engineered nanoparticles in wastewater

Tracking water pollutants:  Study evaluates engineered nanoparticles in wastewater

Have you ever wondered what happens to sunscreen after it swirls down the drain with your soap? Probably not, but it is a question that makes Prof. Chin-Pao Huang curious. Sunscreen contains titanium dioxide, an engineered nanoparticle (ENP) that improves the product’s performance, reducing your sunburn risk while outdoors. But if titanium dioxide doesn’t dissolve, where does it go once you wash it off? Huang, Donald C. Phillips Professor of Civil and Environmental Engineering at the University of Delaware, is principal investigator (PI) of a new grant exploring whether ENP are present in ground wastewater. Murray Johnston, professor in the Department of Chemistry and Biochemistry, serves as co-PI on the project.
