Determination of Trace Elements in Urine of Electroplating Industry Personnel in Longwan District of Wenzhou City with Flame Atomic Absorption Spectrometry / 预防医学

ABSTRACT

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.
