In recent years, the pollution of airborne particulate matter is little improved in Japan and some advanced nations and become more serious in some developing nations. Its analysis is very important for preservation of atmospheric environment. Although airborne particulate matter is a very complex multi-component mixture, usually its mass concentration only or sometimes elemental composition has been measured. It is desirable to develop a systematic analytical method by which many important informations can be efficiently obtained from the same sample.In this study, a systematic method combining water and dilute-acid extraction with ICP-atomic emission spectrometry (AES), ion chromatography and ion-selective electrode has been developed for the determination of water-soluble and dilute-acid soluble components. Several metallic elements were detected and determined in organic solvent-soluble components by ICP-AES.Some compounds in the extraction residues were determined by a combined method of heavy liquid separation and X-ray diffractometry. A simple preparation method of thin-layr standard samples with activated carbon for X-ray spectrometry has been developed and successfully applied to the multi-element determination of airborne particulate matter and its extraction residues. Furthermore, a thermal method has been developed for the fractional determination of elemental carbon and total soluble and insoluble organic compounds in airborne particulate matter. The systematic state analysis of airborne particulate matter can be attained by a combination of these developed methods.

近年来，在日本和一些发达国家，空气中颗粒物的污染几乎没有改善，而在一些发展中国家则变得更加严重。其分析对大气环境的保护具有重要意义。虽然空气中的颗粒物是一种非常复杂的多组分混合物，但通常只测量其质量浓度，有时也测量其元素组成。需要建立一种系统的分析方法，通过这种方法可以从同一样品中有效地获得许多重要的信息。本研究建立了一种结合水和稀酸萃取、icp -原子发射光谱（AES）、离子色谱和离子选择电极的系统方法，用于测定水溶性和稀酸可溶性成分。用电感耦合等离子体发射光谱法（ICP-AES）测定了有机溶剂溶性成分中的几种金属元素。用重液分离和x射线衍射相结合的方法对提取渣中的部分化合物进行了测定。建立了一种简便的用活性炭制备x射线光谱薄层标准样品的方法，并成功地应用于空气中颗粒物及其萃取残留物的多元素测定。此外，已经开发了一种热方法，用于空气中颗粒物中元素碳和总可溶性和不可溶性有机化合物的分数测定。将这些方法结合起来，可以实现空气中颗粒物的系统状态分析。
