六价铬的危害性评价及其检测回顾

The Risk Assessment and Detection Review of Hexavalent Chromium

目的对六价铬的危害性及检测方式进行总结,为未来铬的监测和质量控制提供思路。方法简要总结六价铬的一般形式及暴露源、毒理作用及危害性评价,系统概括六价铬检验研究的情况。结果对铬水平的监测,需要检测其不同氧化态,结合有关毒理研究数据,方可得到更为准确的结果。结论单纯的总铬或不同价态铬的测试结果,不能反映出人类是否处于一个高潜在性的危害状态,因此,作为一种人类必需的元素,铬的危害性评价需要进行综合性的分析。

Objective To provide some considerations for the surveillance and quality control of chromium for future based on the summary of the status of hexavalent chromium risk assessment and analysis. Methods The status of general form, source of exposure, toxic effect and risk assessment were summarized, as well as the situation of hexavalent chromium studies in recent years. Results More accurate results can be obtained through detecting different oxidation states to monitor chromium level in combination with related toxicological research data. Conclusion The test results of total chromium or chromium of different valence cannot reflect whether human are in a potentially high-risk state. Therefore, a comprehensive analysis needs to be conducted of the assessment of hazard of chromium which is a necessary element to human.
