摘要
挥发性有机物是我国“十四五”期间大气环境重点关注的污染因子,对环境空气和废气中挥发性有机物总量的表征方式进行了总结,明确了非甲烷总烃和总挥发性有机物表征内容的联系与区别。通过研究我国环境监测方法标准,对我国现行有效的环境空气、废气和应急监测的挥发性有机物的监测分析方法的采样和进样方式、分析方法原理进行了全面梳理和总结。对现有的挥发性有机物分析新技术和新方法进行了展望,并对我国下一步挥发性有机物方法体系的构建方向提出了建议。
Volatile organic compounds(VOCs)are the major pollution factors of atmospheric environment during the"14th Five-Year Plan"period in China.First,the paper summarized the representation methods of the total amount of VOCs in ambient air and waste gas,and clarified the relationship and difference between the representation contents of NMHC and TVOC.By studying the environmental monitoring methods and standards in China,the current effective monitoring and analysis methods of volatile organic compounds for ambient air,exhaust gas and emergency monitoring in China,including sampling and injection methods,as well as the principles of analysis methods,are comprehensively summarized.At the same time,the existing new technologies and methods for volatile organic compounds analysis are prospected,and suggestions for the construction of the next volatile organic compounds method system in China are put forward.
