对 10 4例云锡冶炼工尘肺进行了调查 ,发现 6 0至 90年代期间尘肺发病工龄非常接近 ,而且与不同生产环境中粉尘浓度密切相关。尘肺病人累积死亡 2 4例 ,病死率为 2 3 0 8%。死因统计结果显示 :直接死因为肺癌者达 45 83% ,居全死因第一。 A survey of 104 cases of tin-tin smelter pneumoconiosis found that the length of the pneumoconiosis episode during the 1960s and 1990s was very close and closely related to dust concentrations in different production environments. There were 24 patients with pneumoconiosis cumulatively and the case fatality rate was 2380%. The cause of death statistics show that: direct cause of death as lung cancer reached 45 83%, ranking first in all causes of death.
