肥料中重金属含量现状、限量和检测标准的研究进展

Research Progress on the Current Status,Limits,and Detection Standards of Heavy Metal Content in Fertilizers

肥料中含有Cd、Hg、Pb、Cr、As等重金属元素,是影响土壤生态和农产品质量安全的重要因素。本文综述了近年来我国肥料重金属含量现状、限量标准和检测标准的研究进展,对国内外肥料中重金属检测方法(如AAS、AFS、ICP-AES、ICP-MS)进行总结,对肥料中重金属检测前处理方法(如电热板消解、高压密闭消解、微波消解等)分析比较,同时进一步指出肥料重金属检测的未来发展趋势和研究方向,以期为相关领域的应用和研究提供参考。

Fertilizers contain heavy metal elements such as Cd,Hg,Pb,Cr and As,which are important factors affecting soil ecology and quality and safety of agricultural products.This paper summarizes the current situation of heavy metal content in fertilizers in China in recent years,the research progress of limit standards and detection standards,summarizes the heavy metal detection methods in fertilizers at home and abroad(e.g.,AAS,AFS,ICP-AES,ICP-MS),and compares the pre-treatment methods for the detection of heavy metals in fertilizers(e.g.,electro-thermal plate ablation,high-pressure closed ablation,microwave ablation,etc.),and at the same time,future development trends and research directions for further detection of heavy metals in fertilizers,in order to provide reference for the application and research in related fields.
