目的研究分析电镀行业人员与健康人群尿液中铜、铁、锰、锌、铬的含量.方法采用新鲜尿液直接进样和经硝酸高氯酸消化处理后样品进行比较分析,应用原子吸收光谱法进行测定分析,数据采用SPSS软件处理.结果对380名调查对象(其中行业人员190名,健康比对人员190名)检测分析发现.电镀行业从业人员中部分标本锌元素含量高于对照组(P<0.01),差异有显著性意义.其他元素未见显著差异.结论通过对人体尿液中微量元素的检测和分析,可以发现职业危害因素的存在,从而予以干预,该方法简便、快速、稳定,相对误差(RSD)小,为2.22%～4.02%,回收率高,为95.2%～106.0%,实用性强,易于推广.

Objective To study the difference of content of Cu、Fe、Mn、Zn、Cr in urine between electroplating industry personnel and health population. Methods Flame atomic absorption spectrometry (FAAS) was used to determine the levels of Cu、Fe、Mn、Zn、Cr in the samples both of fresh urine and the urine treated by nitric acid and perchloric acid. The data was analyzed by SPSS software. Results Among 380 objects (190 industry personnel, 190 health persons), elentroplating industry personnel had significantly higher Zinc level (P < 0.01). Other trace elements levles were not significantly different between the two groups. Conclusion FAAS was a simple, rapid and stable method, with low relative error, 2.22%～4.02% of RSD and 95.2%～106.0% of recovery rate. It were found that some occupational hazards exist.
