RALEIGH – A total of 152 cancer cases in people who attended North Carolina State University (NCSU) have been reported, sparking an internal investigation. The Raleigh, North Carolina-based university is investigating student and alumni exposure to staggering levels of polychlorinated biphenyls (PCBs), a probable carcinogen, in a popular campus building that held classes. Shut down since November 2023, Poe Hall is said to have PCB levels more than 38 times above the Environmental Protection Agency’s (EPA’s) building material standards.
