The results of a medical-environmental evaluation indicates that employees were exposed to toxic concentrations of particulate polycyclic organic matter during roofing operations involving the tear-off of a 7 acre roof (SIC-1761). The particulate polycyclic organic matter includes polynuclear aromatic hydrocarbons, benzo(a)pyrene (50328) and benzo(e)pyrene. Seventy-one percent of all roofers examined gave a history of apparent skin photosensitivity attributed to pitch dust exposures during this project. Ninety-two percent of the examined Caucasian roofers working on this project gave a history of apparent skin photosensitivity attributed to pitch dust exposures occurring during this project. Sixty-five percent of the examined roofers working on this project were observed to have conjunctivitis attributed to pitch dust exposures occurring during this project. These symptoms included lacrimation, chemosis, blepharospasm, lid swelling and blepharitis and conjunctival erythema. There was a statistically significant association between the absence of conjunctivitis in workers exposed to concentrations of 0.11 milligrams per cubic meter of particulate or less and the presence of conjunctivitis in workers exposed to particulate concentrations of 0.18 milligrams per cubic meter or greater. At least 9 employees were exposed to particulate concentrations exceeding the recommended threshold limit values. It appears that the benzpyrene concentrations also exceeded the recommended levels.
