摘　　要：目的探讨吸烟致肺癌与头发中Hg、Cr、Cd、Pb、Cu、Fe、Zn含量的关系。方法选择教师人群,检测成都市40例肺癌教师和健康教师并比较头发中上述7种重金属的含量,并按肺癌患者、吸烟和非吸烟进行对比分析。结果以Hg为代表的挥发性元素在肺癌教师和吸烟教师头发中的含量都较高,肺癌教师头发中元素Hg的含量高于健康教师,差异均有统计学意义(P<0.05)。肺癌教师、吸烟教师、非吸烟教师的人发中Hg的含量虽然也有差异,但P=0.07,差异无统计学意义,这与样本量太少可能有关。其他有毒有害元素的含量在肺癌教师、吸烟教师、不吸烟教师间的比较,差异无统计学意义(P>0.05)。结论因吸烟而进入人体的有害元素汞可能是导致肺癌的原因之一。Objective To investigate the correlation of smoking caused lung cancer with contents of Hg, Cr,Cd,Pb,Cu,Fe,and Zn hair.Methods Teachers were chosen as investigation subjects.Contents of these seven heavy metals in the hair of 40 healthy and lung cancer sufferers were investigated and comparatively analyzed respect to lung cancer sufferers,smokers or nonsmokers.Results The content of volatile element Hg was high in both the hair of lung cancer sufferers and smokers.The Hg content was higher in the hair of lung cancer sufferers than that of healthy teachers;the result showed statistically significant difference（P〈0.05）.Although the hair Hg contents among lung cancer sufferers,smokers and nonsmokers were different,P=0.07,the difference was not significant.The reason might be that the sample was too small.The difference of the contents of other elements in the hair of lung cancers sufferers, smokers and nonsmokers did not show significant difference（P〈0.05）.Conclusions The hazardous element Hg which gets into human body by way of smoking might be one of the causation of lung cancer.
