小气道功能检测应用于接触石棉、硫酸及SO_2气体工人健康状态的研究虽已有若干报道,但迄今尚未见接触煤矿尘工人方面的有关资料。本组检测之研究目的在于运用闭合气量(CV)等小气道功能测定,了解煤矿尘的影响。受检对象为宁夏石嘴山市煤矿井下与井上男性工人。井上工种为从未接触煤矿尘的工人,井下工种为采煤工(66/133)、掘进工和采石工(35/133)以及其它接触粉尘的工种(32/133)。该矿井下1980年的环境检测数据为:煤内游离SiO_2含量6.51％(岩石
Although studies on the health status of small airway function test applied to workers exposed to asbestos, sulfuric acid and SO 2 gas have been reported for some time, no relevant information has been found on workers exposed to coal dust. The purpose of this study is to test the use of closed air volume (CV) and other small airway function test to understand the impact of coal dust. Subjects under inspection for the coal mine in Shizuishan City, Ningxia and downhole male workers. Inverters are workers who have never been exposed to coal mine dust, downhole workers are coal miners (66/133), diggers and quarries (35/133), and other types of dust-contact work (32/133). The underground mine in 1980 environmental testing data: coal free-range content of 6.51% SiO 2 (rock
