PCBs: A Disturbing Legacy and Ongoing Threat

Posted on June 6th, 2014

PCBs were outlawed in the 1970s — so why don’t levels keep going down? Unfortunately, PCBs are almost everywhere. IIHR Research Engineer Keri Hornbuckle is well aware of how thoroughly PCBs have permeated our environment. What she wasn’t expecting to find was PCB11 — which had rarely before been reported — in the air near […]

PCBs: Dredging Up a Problem

Posted on May 11th, 2011

For more than a century, toxins generated by heavy industry settled to the bottom of the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind., creating thick sludgy mud that is home to everything from heavy metals to polychlorinated biphenyls (PCBs). The U.S. Army Corps of Engineers has announced plans to dredge the canal, but the plan raises questions for scientists.

Aboard the Lake Guardian

Posted on March 30th, 2011

In September 2010, IIHR Research Engineer Keri Hornbuckle and a small group of student researchers set sail aboard the EPA research vessel Lake Guardian to collect air and water samples for PCB testing. They boarded the vessel at Navy Pier in Chicago. Click on any image to start the slideshow. Photos by University Relations photographer […]

Green technology is more than a catchphrase for Jerry Schnoor. He and his research team are using the greenest of technologies—poplar trees and other plants—to break down some of the most toxic substances in the environment. “I think the reason it’s so promising is because it is truly a green technology that’s low cost and […]
