Lung function among 599 white male employees of a southeastern Tennessee copper mine/smelter operation was compared according to smoking history and occupational experience. The job categories compared included employees with work histories in low sulfur dioxide [SO2] environments (both underground mining and non-mining), in high SO2 exposure work areas, and in those with transient exposure to SO2. Miners with low SO2 exposure were found to have lower lung function indices (both FVC AND FEV1) than did employees in other job categories. Smoking history was strongly associated with low FEV1. After adjusting for smoking history, cumulative long-term exposure to SO2 was not demonstrated to contribute to decreased lung function.
根据吸烟史和职业经历，对田纳西州东南部一家铜矿/冶炼厂的599名白人男性员工的肺功能进行了比较。所比较的工作类别包括有在低二氧化硫[SO2]环境（地下采矿和非采矿）、高SO2暴露工作区域以及短暂接触SO2工作经历的员工。发现低SO2暴露的矿工的肺功能指标（FVC和FEV1）低于其他工作类别的员工。吸烟史与低FEV1密切相关。在对吸烟史进行调整后，未证明长期累积接触SO2会导致肺功能下降。
