摘要
大气颗粒物中含有多种化学物质,组分复杂,主要包括水溶性离子、碳组分和无机元素等.复杂的化学组分不但污染生态环境,而且严重威胁人体健康.为识别大气颗粒物中化学组分的贡献程度、减少大气颗粒物对生态环境及人体的危害,故对颗粒物化学组分的污染特征及来源进行分析.在大气颗粒物及其化学组分的分析方法中,除质量浓度的基础分析外,还包括基于其组分特性的进阶分析方法,主要包括水溶性离子的阴阳离子平衡及酸碱度、硫和氮的转化率及氮硫比分析;碳组分中有机碳与元素碳比值分析、二次有机碳估算及不同碳组分表征来源分析;无机元素的富集因子法分析等.通过对进阶分析方法及应用进行汇总,进一步明确各组分污染特征,识别组分来源,为后续来源解析及污染管控措施制定提供依据.
Abstract
Atmospheric particles contain a variety of chemical substances,mainly including water-soluble ions,carbon components and inorganic elements.In order to identify the contribution of chemical components in atmospheric particulate matter and reduce the harm of atmospheric particulate matter to the environment and human body,it is necessary to analyze the pollution characteristics and sources of chemical components of particulate matter.The analysis methods of chemical components of atmospheric particulate matter mainly include anion and cation balance and pH of water-soluble ions,conversion rate of sulfur and nitrogen,and nitrogen-sulfur ratio analysis;analysis of the ratio of organic carbon to elemental carbon in the carbon component,estimation of secondary organic carbon,and source characterization of different carbon components;enrichment factor analysis method of inorganic elements,etc.By reviewing the analysis methods and applications,the analysis methods and application objects of the pollution characteristics of each component are further clarified,providing a basis for subsequent source analysis and the formulation of pollution control measures.
