摘　　要：水是生态系统中必不可少的重要资源,也是人体中的重要组成成分。随着经济的不断发展工业化进程不断加快,各种矿产资源被开发和利用,导致地下水污染越来越严重。其中最值得研究的就是重金属污染现象,如果地下水中的重金属超出人们日常饮用标准,将会对人们的健康造成很大危害,甚至威胁着人们的生命安全。因此,对地下水中重金属含量的检测就显现得尤为重要。其中在较低含量元素方面例如重金属,人们常采用电感耦合等离子体法,其因具有检出限较低、分析速度快精密度较高等优势被人们普遍应用。该文利用电感耦合等离子体质谱法研究山东省菏泽市地下水中重金属元素镉(Cd)、铬(Cr)、铜(Cu)、锰(Mn)、铅(Pb)和锌(Zn)含量,为进一步追踪菏泽地区重金属来源、迁移规律及综合治理提供一定的科学依据。Water is an essential resource in the ecosystem and important component of the human body. With the continuous development of the economy, the industrialization process has been accelerated, and various mineral resources have been developed and utilized, resulting in more and more serious groundwater pollution. One of the most worthy of study is the phenomenon of heavy metal pollution. If the heavy metals in groundwater exceed people’s daily drinking standards, it will cause great harm to people’s health, and even threaten people’s life safety. Therefore, it is particularly important to detect the content of heavy metals in groundwater. Among heavy metals of low-content elements, the inductively coupled plasma method is often widely used due to its advantages of low detection limit, fast analysis speed and high precision. In this paper, the contents of heavy metal elements, such as cadmium(Cd), chromium(Cr), copper(Cu),manganese(Mn), lead(Pb) and zinc(Zn) in groundwater of Heze City, Shandong Province were studied by inductively coupled plasma mass spectrometry, which provides a certain scientific basis for further tracing the source, migration law and comprehensive management of heavy metals in Heze area.
