摘要
对四个接镍作业厂矿进行了肿瘤回顾性队列调查。观察组全死因、恶性肿瘤粗死亡率与相对应对照组相比差异无显著性。镍精炼厂男性肺癌粗死亡率61.91/10万,其SMR以不同参比标准,可达253.17～451.13,且有统计学意义。某镍矿肺癌粗死亡率为24.60/10万,以全国及当地一般人群作参比琼准时SMR分别为289.86,975.61(P<0.01)。镍精炼、冶炼工肺癌死亡危险度增高在我国也得到了证实。
A retrospective cohort study was carried out in four occupational populations exposed to nickel.In the mor-
talities of all causes of death and malignancies.there were no statistically significant differences between nickel
exposed populations and control groups.The male workers' mortality of lung cancer in a nickel refinery was 61.
91/10~5,and the SMRs were 253.17-451.13 compared with the different reference populations.having statistical
significances.The crude mortality of lung cancer in a nickel mine was 24.60/10~5.and the SMRs were 289.86
and 975.61 compared with the nation and local references respectively.These demonstrate that the risk of mor-
tality of lung cancer in nickel smeltery and refinery workers in China is increased.
