The respiratory effects of occupational exposure to airborne metalworking fluids were studied in 1,042 currently employed male machinists from three General Motors automobile facilities. Workers completed an American Thoracic Society questionnaire containing additional questions, and current aerosol exposure levels and spirometry data were determined for each worker. There were 769 assembly workers in an internal reference group; they had no direct exposure to metal working fluids. Currently exposed workers had higher prevalences of all respiratory symptoms studied except asthma compared with assembly workers. Workers exposed to synthetic fluids had the highest prevalences of cough, phlegm, wheezing, breathlessness, and chronic bronchitis; the lowest symptom prevalence levels were reported by those currently working with soluble oils. Significantly elevated odds ratios for cough, phlegm, wheeze, and chronic bronchitis were seen for machinists exposed to any type of metalworking fluid compared with assembly workers. Cough, phlegm, and wheeze were significantly elevated in those exposed to either straight or synthetic fluids. Odds ratios were consistently higher among those exposed to synthetic fluids. The strongest and most significant predictor of respiratory symptoms was smoking. The current symptoms were associated only with current exposures to straight or synthetic fluids.
