大气颗粒物元素浓度采样方法研究

Research on Sampling Methods for Element Concentrations of Atmospheric Particulate Matter

大气颗粒物是灾害天气污染物的重要组成之一,要求借助有效地方式对其进行采样监测与研究。结合传统的大气颗粒物监测方法而言,存在着较多的技术阻碍,无法满足大范围、高分辨率的空气质量监测,不过在了解大气颗粒物的物化特征后,可以基于地气测量法的原理,使用新的采样方法满足环境保护工作的需要。为此,会先阐述动态地气测量技术及优化大气采样的原理,然后具体分析采样工作的开展,最后进行采样结果讨论,以期望可以为环境保护工作起到支持作用。

Atmospheric particulate matter is one of the important components of hazardous weather pollutants,which requires effective local sampling,monitoring,and research.Compared to traditional methods for monitoring atmospheric particulate matter,there are many technical obstacles that cannot meet the needs of large-scale and high-resolution air quality monitoring.However,after understanding the physicochemical characteristics of atmospheric particulate matter,a new sampling method can be used based on the principle of ground gas measurement to meet the needs of environmental protection work.To this end,this paper will first elaborate on the principle of dynamic geogas measurement technology and optimization of atmospheric sampling,then analyze the implementation of sampling work in detail,and finally discuss the sampling results,hoping to play a supporting role in environmental protection work.
