Worker exposures to carbon-monoxide (630080), sulfur-dioxide (7446095), nitrogen-dioxide (10102440), formaldehyde (50000), respirable particulates, and airborne fungus were determined at the Health Services Administration Building (SIC-8091) in Hyattsville, Maryland, on November 10, 11, and 12, 1980. A representative of the Center for Environmental Health requested the evaluation on behalf of several employees who reported symptoms of chest tightness, cough, shortness of breath and eye, nose, and throat irritation. Carbon-monoxide concentrations ranged from 0 to 6 parts per million (ppm), compared with the OSHA Standard of 50ppm. No sulfur-dioxide, nitrogen dioxide or formaldehyde concentrations were detected. Respirable particle concentrations ranged from 0.01 to 0.15 milligrams per cubic meter. Fungal colony forming units per cubic meter in the basement ground floor samples were not statistically different from the samples obtained from the other, unaffected floors. There are no standards for airborne fungus concentrations chest radiographs and pulmonary function test results produced no clear pattern of disease. The authors conclude that the etiology of the reported symptoms could not be determined. They recommend that the ventilation systems be routinely cleaned, maintained and operated to reduce temperature and relative humidity and the chance of airborne fungal contamination.
