矿工肺癌问题近年受到国内外的重视。大量资料表明,早年井下氡浓度的增加是很多地方发生矿工肺癌的首要原因,某些矿山同时存在的砷污染也有一定作用。1978年我们调查了湖南某硫铁矿近年发生的9例肺癌,认为砷是引起肺癌的主要原因,今报告 Miner’s lung cancer problem has received attention at home and abroad in recent years. A large number of data indicate that the increase in underground radon concentrations in early years is the primary cause of the occurrence of lung cancer among miners in many places. The simultaneous presence of arsenic pollution in certain mines also has a role. In 1978, we investigated 9 cases of lung cancer that occurred in a pyrite mine in Hunan in recent years. We believe that arsenic is the main cause of lung cancer.
