本研究通过对炼焦作业工人的血硒、发硒、外周血淋巴细胞微核以及染色体畸变等生化、遗传指标的分析表明：炼焦作业工人血硒、发硒与对照比较未见明显异常（Ｐ＞０．０５），提示焦化作业工人肺癌的高发与机体内硒的缺乏无必然联系。焦炉工人外周血淋巴细胞微核率，染色体畸变率均增高，由此说明炼焦生产可产生某些致突变物质，这些物质可能与焦炉工人癌症高发有一定联系。故应加强对染色体畸变率明显增高人群的监护。
In this study, biochemical and genetic indexes such as blood selenium, selenium, peripheral blood lymphocyte micronucleus and chromosome aberration of coking workers were analyzed. The results showed that there was no obvious abnormalities in serum selenium, selenium and control (P> 0.05), suggesting that the high incidence of lung cancer in coking workers and the lack of selenium in the body are not necessarily related. Coke oven workers peripheral blood lymphocytes micronucleus rate, chromosome aberration rates were increased, indicating that coking production can produce some mutagenic substances, these substances may be associated with high incidence of cancer in coke oven workers have a certain link. It should be strengthened on the chromosome aberration rate was significantly higher custody of the crowd.
