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.
