Abstract

An analytical method for the determination of toxicological relevant species of arsenic in urine was developed and validated using hydride generation microwave-induced emission spectrometry (HG-MP-AES). This strategy can be used as an alternative to HG-HPLC-ICP-MS considered as a reference technique for arsenic speciation. This procedure is notably less expensive than other techniques and sample preparation and requires only a few steps.

•
Hydride generation with MP-AES detection has proven to be an effective technique for measuring arsenic metabolites in urine, which is relevant for occupational monitoring and health risk assessment purposes.
•
This method offers simplicity and cost-effectiveness, serving as an alternative to classical analytical procedures typically used for arsenic analysis in urine.
•
The methodology has been successfully applied for the purpose of workers' health surveillance.

利用氢化物发生微波诱导等离子体光发射光谱法测定尿液中与毒理学相关的砷种类

利用氢化物发生微波诱导发射光谱法（HG-MP-AES）开发并验证了测定尿液中砷的毒理学相关种类的分析方法。该方法可作为 HG-HPLC-ICP-MS 的替代方法，被视为砷分类的参考技术。与其他技术和样品制备相比，该程序的成本明显较低，而且只需几个步骤。-氢化物发生与 MP-AES 检测已被证明是测量尿液中砷代谢物的有效技术，与职业监测和健康风险评估目的相关。
