对１２１名滑石接尘退休工人进行了肺功能损害的调查及其影响因素分析。结果表明：不论吸烟与否，退休接尘工人ＦＶＣ、ＦＥＶ１、ＭＭＦ、Ｖ５０、Ｖ２５等指标的实测值、实测值／预计值（％）较对照组明显降低，异常率则明显升高，且多具有显著或非常显著的统计学意义。多因素分析表明：慢性支气管炎和接尘工龄是影响退休接尘工人肺功能下降的主要因素。
A survey of 121 patients with retired talc dust exposed to lung function damage and analysis of its influencing factors. The results showed that the actual measured value / predicted value (%) of the index of FVC, FEV1, MMF, V50, V25 and so on were significantly lower than those in the control group and the abnormal rate was significantly higher Significant or very significant statistical significance. Multivariate analysis showed that: Chronic bronchitis and dust exposure are the main factors affecting the decline of lung function in retired workers exposed to dust.
