石场接尘工人肺通气功能检查结果分析

Analysis on pulmonary function test results of quarry workers exposed to dust

目的探讨石场接尘工人肺通气功能异常情况。方法运用流行病学手段，对8间石场260例接尘工人进行肺功能测定泡括FVC、FEV1、MMF、V50、V75），并与246例无接尘正常工人做对照。结果石场接尘工人肺通气功能显著低于对照组工人，肺通气功能异常有随着工龄增长而增加的趋势，并女工肺功能异常率高于男工。结论石场接尘人工肺功能有损伤，并在接尘工龄、性别上有差异，因此，提倡加强职业防护，做好粉尘作业工人健康监护。

Objective To investigate the pulmonary function abnormalities of quarry workers exposed to dust. Methods Epidemiological tools was used to detect and analyze 260 workers exposed to dust from 8 quarry （including FVC, FEV1, MMF, Vso, VTs）, compared with 246 cases of regular workers without dust exposure as control. Results The pulmonary function of workers exposed to dust quarry was significantly lower than that of the control group, lung function abnormalities increased with length of service with the trend, and female workers＇ lung function abnormalities was higher than that of male workers. Conclusion Damage is detected to lung function of quarry workers, and there is difference in dust seniority and gender, therefore, the occupational protection should be strengthened, and health surveillance records should be implemented to dust-exposed workers.
