Abstract
Radiation hazards from video display terminals and automatic stock quote display boards and health hazards from cigarette smoke on the options and equity trading floors of the Midwest Stock Exchange (SIC- 6231), in Chicago, Illinois were evaluated on June 5 and October 11, 1978. The stock exchange management requested the evaluation on behalf of an unspecified number of floor workers. Breathing zone atmospheric samples were analyzed for total airborne particulates, carbon-monoxide (630080), and selected polynuclear aromatic hydrocarbons (PNAs). PNAs were not detected, and carbon-monoxide concentrations were well below the OSHA standard of 50 parts per million time weighted average. Total airborne particulate matter was well below the OSHA standard for nuisance dust of 15,000 micrograms per cubic meter of air but exceeded EPA community air quality standards for suspended particulate matter. The investigators note that radiation measurements were not made because NIOSH had determined in a 1977 survey of video display terminals that radiation emissions were well below the OSHA standard of 2.5 milliroentgens per hour for X-rays and well below threshold limits set by other groups for ultraviolet, visible, infrared, and radio frequency radiations. They conclude that neither video display terminals nor cigarette smoke on the stock exchange equity trading floor constituted an occupational health hazard.
