University of Iowa researchers have confirmed that sediments of the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind., are contaminated with polychlorinated biphenyls (PCBs). The IHSC, part of the Calumet River tributary of Lake Michigan, will begin being dredged in the next few years to maintain the proper depth for ship traffic, with uncertain environmental impacts in regard to PCBs. Scientists aren't sure whether dredging will help the situation by removing the potentially harmful...

Even the snow on Aconcagua Mountain in the Andes is polluted with PCBs. An international team of researchers detected low concentrations of these toxic, carcinogenic chlorine compounds in samples taken from America's highest mountain. The snow samples taken at an altitude of 6200 meters are among the highest traces found anywhere in the world of these substances, which have been banned since 2001. In particular, the samples contained more persistent compounds like hexachlorobiphenyl (PCB 138)...

New method targets oil sheen, other pollutants Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. "We are not trying to treat the entire...

The EPA says that hundreds of school buildings across the U.S. have caulk around windows and doors that contain potentially cancer-causing PCBs. It is not known how many schools could be affected, nor the danger it causes to students.  However, the agency is still telling schools to test old caulk and remove it if PCBs turn up in significant amounts. Lisa Jackson, EPA Administrator, said PCBs remain in schools and many other buildings built before the chemicals were banned in the late...
