Environmental air was analyzed for sulfuric-acid (7664939), sulfur- dioxide (7446095) and phosphates, and noise level measurements taken, at the Publishers Paper Company (SIC-2621) in Newburg, Oregon, on April 14 to 16, 1981. A representative of the Association of Western Pulp and Paper Workers requested the evaluation to determine if vocal cord nodules experienced by two of four paper machine tenders were caused by their exposure to a combination of chemicals and high noise. Sulfur-dioxide concentrations ranged from about 0.01 to 0.95 parts per million (ppm) compared with the NIOSH standard of 0.5ppm. Sulfuric-acid concentrations ranged from about 0.01 to 0.06 milligrams per cubic meter (mg/Cum), compared with the NIOSH standard of 1mg/Cum. Concentrations of phosphates ranged from less than 0.01 to potential noise exposure that ranged from 94 to 101 decibels on the A-weighted scale (dBA), compared with the NIOSH recommended criteria of 85dBA. The author concludes that there may be a relationship between the occurrence of vocal cord nodules and exposure to high noise levels and respiratory irritants. He recommends raising the pH level of the pulp liquor, use of air supplied respirators, use of an electric communication system, and medical examination of workers experiencing persistent hoarseness.
