A study from the University of Iowa finds that common building materials found in older schools could be impacting student health.

Study finds PCB concentrations are higher inside schools than out, implicating building materials.

University of Iowa researchers have found cancer-causing chemicals in some older Iowa schools.

A new study has found that concentrations of airborne polychlorinated biphenyls, or PCBs, inside schools could expose students to the compounds at higher levels than through diets.

A recent study found that concentrations of airborne PCBs inside schools could result in some students inhaling the compounds at higher levels than they would consume through their diets.

A study released Friday by the University of Iowa that included four East Chicago schools concluded the presence of aging caulking and light fixtures may lead to diminished air quality inside the buildings.

Sediment contaminated with polychlorinated biphenyl, or PCBs, from the bottom of the New Bedford Harbor is the number one source of airborne PCBs in the neighborhoods surrounding the port, according to new research.

Study labels the harbor the largest reported source of PCBs in ambient air in North America, though experts say levels are within accepted range.

Dr. Keri Hornbuckle, a professor of engineering at the University of Iowa, says chemicals known as PCBs are found in clothing, paper, paint and even in the air.

Since polychlorinated biphenyls (PCBs) are produced through industrial processes or activities, it is assumed that people living in industrial cities will have higher concentrations of these toxic chemicals in their blood than people in rural communities. Researchers at the University of Iowa say this isn’t the case.
