)[摘 要] 目的:检测长白山天然矿泉水中锂、铍、铝、钒、锰、钴、镍、铜、锗、砷、硒、铷、钼、银、锡、铯、锑和钡18种微量元素的含量,为评价长白山天然矿泉水质量提供参考。方法:采集吉林省长白山靖宇县五龙泉、神龙泉、银龙泉和林海泉4处天然矿泉水,水样经酸化后直接采用电感耦合等离子体-质谱(ICP-
MS)法进行检测。结果:被测元素的检出限为0.005~0.573μg
·
L-1,除硒元素外,其他元素相对标准偏差为0.1%~4.5%,回收率为81%~116%;4处矿泉水中的18种微量元素含量均符合GB 8537-
2008饮用天然矿泉水卫生标准。结论:ICP-MS方法检出限低,具有良好的准确度和精密度,适用于多种元素快速检测;长白山靖宇县4处天然矿泉水中18种微量元素含量均符合国家饮用天然矿泉水卫生标准。

  随着社会经济的发展,矿泉水已经进入人们日
常生活之中。虽然矿泉水中的微量元素含量较低,
但长期饮用对人体有着重要的生理意义。微量元素
在预防疾病方面有着重要作用[1-2],如硒可预防东北地区的克山病和大骨节病[3];铜可预防贫血、骨质疏松等[
