Environmental air samples were analyzed for fibrous glass, general organics, metals, asbestos (1332214), and polychlorinated-biphenyls (1336363) (PCBs) at Our Lady of Visitation Elementary School (SIC- 8210), in Cincinnati, Ohio, on February 9 to 20, 1981. Medical interviews and examinations were also conducted. The principal of the school requested the evaluation in response to an outbreak of skin rash, watery eyes, and breathing problems among students and teachers. Air sampling revealed no detectable concentrations of asbestos, PCBs, or fibrous glass. Samples analyzed for organics showed only carbon-tetrachloride (56235) at concentration of 0.04 to 65mg/cum. Metal concentrations in dust samples were considered normal for settled dust. Skin symptoms reported were generally described as a burning or itching. There was no consistent association between time of day, activity, or weather and there was no obvious clustering of symptomatic students within the classrooms. The authors conclude that the cause of the adverse health reactions could not identified and that the symptoms and physical findings present were not typical of any known environmental exposure.
