对郑州某纺织机械厂铬接触工人的外周血淋巴细胞微核率进行了测定，结果表明在作业环境铬酸雾浓度不超标（Ｘ＝０．０３ｍｇ／ｍ３）的情况下，观察组淋巴细胞微核率比对照组明显升高，差异有显著性意义（Ｐ＜０．０５），工龄６年以上工人的淋巴细胞微核率显著高于对照组，差异有非常显著性（Ｐ＜０．０１），接触工人中尿铬超标组的淋巴细胞微核率亦显著高于尿铬正常组，差异有非常显著意义（Ｐ＜０．０１）。提示长期低剂量铬接触，可造成人体遗传物质的明显损害。
The micronucleus rate of peripheral blood lymphocytes of chrome exposed workers in a textile machinery factory in Zhengzhou was measured. The results showed that in the case of chromic acid mist concentration is not exceeded (X = 0.03mg / m3), observation group lymphocyte micro (P <0.05). The micronucleus rate of lymphocytes in workers of 6 years of age was significantly higher than that of the control group, the difference was significant (P <0.01) ). The micronucleus rate of lymphocytes in the urine-chromium-excess group exposed workers was also significantly higher than that in the normal urine-chromium group (P <0.01). Prompted long-term low-dose chromium exposure, can cause significant damage to human genetic material.
