土壤重金属监测技术研究

Research on monitoring technology of soil heavy metals

针对土壤重金属污染问题日益严重的局面,如何提高重金属污染监测精度和速度是亟待解决的问题。文章立足于我国土壤重金属污染现状,重点介绍了实验室监测法和现场快速监测法,认为前者精度高、耗时长、成本高,后者成本低、耗时短、精度相对较低。此外,土壤重金属污染监测是确保我国粮食安全的基础,具有重要的现实意义。

In view of the increasingly serious problem of soil heavy metal pollution, how to improve the accuracy and speed of heavy metal pollution monitoring is an urgent problem to be solved.Based on the current status of soil heavy metal pollution in my country, this article focuses on the laboratory monitoring method and the on-site rapid monitoring method.It is believed that the former has high accuracy, time-consuming and high cost, and the latter has low cost, short time and relatively low accuracy.In addition,soil heavy metal pollution monitoring is the basis for ensuring my country’s food security and has important practical significance.
