摘要

To evaluate possible adverse health effects including cancer and heart disease, NIOSH investigators conducted a combined environmental and medical evaluation. For all substances monitored, the levels obtained represent potential exposures since workers wore dust respirators. Overall dust levels were generally lower than reported in previous company environmental data and may reflect decreased production at the time of the NIOSH survey. Results for the questionnaire showed a high prevalence (32%) of chronic bronchitis in the current workforce. The PMR results showed a statistically significant elevation in deaths from chronic obstructive pulmonary disease (COPD) and COR pulmonale (PMR 148 and 187), when compared to the United States general population.
