NIOSH 1975 Apr; :1-187
An occupational health prevalence study of chronic respiratory disease in 457 male aluminum (7429905) potroom workers is undertaken. The tests consist of an interviewer administered questionnaire, forced spirometry, closing volume determination, chest X-ray, sputum cytology, serum alpha-1 antitrypsin, serum trypsin inhibitory capacity, blood pressure, and urine and serum fluoride. The prevalence of respiratory disease is 4.9 percent in the aluminum workers and 5.3 percent in the controls. The prevalence ratios are examined for workers using different processes, for potroom exposure history, and current employment status. No significant differences are observed. The aluminum workers have more abnormalities in closing volume measurements and more mild atypia of the sputum. (Contract No. 099-73-0086)
