“…However, the prevalences of chronic cough, chronic phlegm, and chronic shortness of breath reported at the zinc mines were significantly different than those reported in the nonexposed blue-collar workers (p <.01) (11) (Table XIX). Height, age, and smoking-adjusted mean values of pulmonary function for underground and surface workers indicated no differences between the two groups.…”

“…Data on respiratory symptoms and pulmonary function from a study of unexposed blue-collar workers were available for this purpose. Although some results from the blue-collar study have been published, (8,9,10) the data were retabulated for this health hazard evaluation. FEV 1 and FVC in Troy miners were compared to predicted values for current, former, and nonsmoking blue-collar workers (9) and to predicted values for nonsmokers.…”

.Personal breathing zone and area environmental samples were collected to characterize employees' exposures to oxides of nitrogen (NO, NO 2 ), coal tar pitch volatiles (CTPV's), polynuclear aromatic hydrocarbons (PNA's), diesel particulates, carbon monoxide (CO), aldehydes, respirable silica, and noise. The 54 passive dosimeters analyzed for oxides of nitrogen indicated that the full shift exposure levels of NO 2 ranged from 0.16 ppm to 4.61 ppm with a mean exposure of 1.45 ppm. These results indicate that exposures were in excess of the NIOSH recommended ceiling level of 1 ppm. Results of the area samples for CO appeared to be well below the evaluation criteria. A concentration of 0.1 ppm was recorded on 2 of the 17 area measurements for formaldehyde.The medical portion of the survey consisted of a medical questionnaire, spirometry, and a review of company collected chest radiographs and audiograms. One hundred twenty-two of the 314 (39%) employees participated in the study. When compared to a group of nonexposed blue-collar workers, there was an increased prevalence of chronic respiratory symptoms. Review of 293 radiographs revealed 18 cases of ILO category 1/0 or greater small radiographic opacities and no cases of large This Health Hazard Evaluation (HHE) report and any recommendations made herein are for the specific facility evaluated and may not be universally applicable.

Analysis of the audiograms revealed a pattern typical of a population which has been exposed to excessive noise and suggested deficiencies in the company's hearing conservation program.The medical findings suggested a pattern of obstructive airways disease and pneumoconiosis. Acute symptoms were consistent with exposure to diesel particulate. Whether the chronic health problems have been the result of exposures in the Troy Mine is unclear. Because of the low participation rate, a selection bias may exist.On the basis of the environmental data obtained during the survey, NIOSH has de...

“…Likelihood ratio tests for goodness-of-fit were used to compare the responses to questions about chronic cough and chronic phlegm to the prevalences expected if the workers at the International Salt mine had the same symptom prevalences reported by the non-exposed blue-collar workers. (10) Knowledge of each employee's smoking history was used to calculate the expected prevalences of these respiratory symptoms. Percent predicted pulmonary function values were calculated using Knudson's prediction equations.…”
