Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 75-28-210, 1975 Jul; :1-5
Air quality measurements demonstrated that the exposure of Western States Bankcard Association (SIC-6022) employees to nitrogen-dioxide (10102440), formaldehyde (50000), sulfur-dioxide (7446095), carbon- monoxide (630080), and hydrogen-sulfide (7783064) originating from a nearby sewage treatment plant and a bus parking lot, were not toxic at the concentrations measured during the NIOSH evaluation. The sewage odors were occasionally offensive. It was estimated that some quantities of substances in the outside air surrounding could eventually enter the Western State building, although not in toxic quantities.
