非甲烷总烃、VOCs、TVOC的区别及其在建设项目环境影响评价中的应用

Difference between NMHC,VOCs,TVOC and It's Application in Environmental Impact Assessment of Construction Project

在建设项目环境影响评价中,非甲烷总烃、VOCs、TVOC这三个污染因子经常混淆使用。本文从非甲烷总烃、VOCs、TVOC三个污染因子的定义、监测方法等方面研究了三个因子的差异,并根据其差异,在环评工作中加以运用;提出多种有机污染物评价因子的识别、筛选原则,讨论了相应评价标准的选取方法和环境现状监测中应注意的事项。

NMHC, VOCs and TVOC were usually incorrectly used in the Environmental impact assessment of construction project. From the perspective of definition and monitoring method,the difference between NMHC, VOCs and TVOC was studied. According to the difference, this article presented the principle and method of identifying and screening Environmental factors, discussed the method of selecting assessment standard and matters needing attention in Environmental monitoring of Environmental impact assessment.
