采样容器对环境空气中非甲烷总烃检测结果的影响

Effect of Diff erent Sampling Containers on the Detection Results of Non Methane Total Hydrocarbons in Environmental Air

随着工业化和城市化的发展,环境空气污染问题日益严重。非甲烷总烃是一类重要的大气污染物,其浓度反映了空气污染的程度。因此,准确地测定非甲烷总烃的浓度对于环境保护具有重要意义。然而,采样容器的选择对非甲烷总烃的检测结果有着重要影响。本研究选取了玻璃瓶、不锈钢容器、聚合物袋、积雪采集器和活性碳管作为采样容器,对比了它们对非甲烷总烃检测结果的影响,旨在为实际工作提供参考。

With the development of industrialization and urbanization,the problem of environmental air pollution is becoming increasingly serious.Non methane total hydrocarbons are an important class of atmospheric pollutants,and their concentration reflects the degree of air pollution.Therefore,accurately measuring the concentration of non methane total hydrocarbons is of great significance for environmental protection.However,the selection of sampling containers has a significant impact on the detection results of non methane total hydrocarbons.This study selected glass bottles,stainless steel containers,polymer bags,snow collectors,and activated carbon tubes as sampling containers to compare their effects on the detection results of non methane total hydrocarbons,aiming to provide reference for practical work.
