Analysis Method of Pollution Characteristics of Main Chemical Components of Atmospheric Particulate Matter
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.
