过去对煤矿在职矿工接触粉尘与肺功能的关系研究较多。本研究目的是(1)证实过去的有关结论;(2)调查离职矿工肺功能对粉尘的反应是否与在职矿工不同。选曾参加过英国尘肺普查的矿工,有完整肺功能检查结果和其他资料者4833例,于1974—1980年间进行跟踪调查,分为在职矿工、65岁以下和65岁以上离职矿工三组。取第一秒时间肺活量(FEV_1)、用力 In the past, there was a lot of research on the relationship between miners’ contact dust and lung function. The purpose of this study was to (1) confirm past relevant findings, and (2) investigate whether the lung function of the departing miners responded differently to the dust than the working miners. Among the 4833 miners who had taken part in the British pneumoconiosis survey and who had complete pulmonary function tests and other information, they conducted follow-up surveys between 1974 and 1980 and were classified into three groups: working miners, those under 65 years and those who left the mine aged 65 and over. Take the first second time vital capacity (FEV_1), force
