Abstract
An on site visit was made to Airco Carbon (SIC-3624), a producer of carbon products, to gather data concerning the feasibility of using this facility in an industrywide industrial hygiene and epidemiology study of the carbon products industry. Two different product lines were manufactured at this facility: specialty graphite products, and graphite electrodes. Raw materials for both lines included petroleum coke, coal tar pitch, and petroleum pitch. Airborne samples were shown to contain 17 polycyclic aromatic hydrocarbon (PAH) compounds; all of these compounds were listed as tumorigenic and several were positive animal carcinogens. Overall levels of the compounds were low. The areas of the facility involved in formulation and baking appeared to have the highest overall concentrations. Ventilation appeared to be effective in reducing these levels. The author concludes that this particular facility is not suitable for inclusion in the larger project because it is impossible to identify a population of workers with an exposure of adequate duration to only petroleum pitch. To assign either source (coal tar pitch or petroleum pitch) to the PAHs identified in the two major areas where levels of PAHs were detected, would have been exceedingly difficult.
