Respiratory health effects among coal miners exposed to diesel exhaust emissions were investigated. Nearly 1000 miners at six operations were examined. Examinations included posterior/anterior and left lateral chest films, a minimum of five spirometric maneuvers, administration of a respiratory questionnaire, employment and smoking history, and determination of selected demographic characteristics. A dry rolling sealed spirometer was used for lung function testing. A sample of miners at the diesel use mines was asked to wear a personal dust sampler that would perform similarly to the human respiratory system with respect to deposition and retention of different sized particles. Each subject was asked to wear tandem passive dosimeters to measure concentrations of nitrogen- dioxide (10102440). Significantly more underground and surface miners exposed to diesel emissions reported persistent cough and phlegm than their comparisons. Diesel exposed individuals had somewhat lower pulmonary function performance than comparisons. The authors conclude that disparities in various health characteristics between workers in or at diesel use mines and their matched comparisons indicate no significant trend.
