A University of Iowa PhD student has won a top research paper award for his investigation of polychlorinated biphenyls (PCBs), a toxic chemical banned decades ago. 

Jason Hua, a year PhD student studying civil and environmental engineering and advised by Prof. Keri Hornbuckle, discovered significant emissions of PCBs from school building materials, such as glass block windows, joint caulking, and fireproof coating steel columns.

"Our findings underscore the risks of PCB-containing building materials in schools and guides state and school officials towards effective remediation, reducing exposure among children and school staff," Hua said. 

This research has earned Hua the C. Ellen Gonter best research paper award through the American Chemical Society. Hua will present his findings during an American Chemical Society meeting this month. 

The research, in collaboration with Vermont state and school officials, focused on schools in Vermont. Hua contributes to the Iowa Superfund Research Program, which is led by Hornbuckle. Hornbuckle is a UI Distinguished Chair and professor of civil and environmental engineering.
