摘要
含碳气溶胶采样偏差是影响含碳气溶胶及大气颗粒物精确测定的主要因素之一,进而影响大气颗粒物的源解析、环境效应分析、污染防治对策制定等。分析了含碳气溶胶采样偏差的产生原因,综述了目前研究所用的衡量采样偏差的方法,并分析了方法的优缺点,探讨了引起采样偏差的主要影响因素,最后对今后的相关研究方向进行了展望。
Carbonaceous aerosol sampling artifact, one of the main factors affecting accurate measurement of carbonaceous aerosol and atmospheric particulate matter, could influence source apportionment of atmospheric partic- ulate matter, environmental effect analysis, pollution prevention and control measures, etc. In this paper, compre- hensive analysis of research on carbonaceous aerosol sampling artifact at home and abroad has been conducted, and the research significance and present situation of carbonaceous aerosol sampling artifact have been discussed in terms of the causes, research methods, influencing factors, etc. In addition, it illustrates the advantages and disadvantages of current research methods and predicts the possible research direction.
