To discriminate the sources of sulfur compounds in environment and discuss their behavior, isotopic measurement was carried out for the source sulfur which is generated by burning of fossil fuels and environmental sulfur which is included in air and suspended particulate matter. The results shows that sulfur in air is attributed to petroleum and sulfur in suspended particulate matter is attributed to coals. To collect air sample for the isotopic measurement, it takes about 50 days and is required to add absorbing solution once a week. In this project the new method for the collection of air sample was investigated by using activated carbon fiber. Sulfur dioxide in air sample was collected almost : it the efficiency of lO0%. This collection method is also able to shorten the collecting time. Simple qualitative analysis of inorganic components of suspended particulate matter was investigated by infrared spectroscopy. Sample is mixed with carbon and KBr and pressed before analysis. Several main inorganic components, sulfate, ammonium, silicate etc., are possible to be analyzed. Selenium isalso determined for coals and petrolenium to help the discussion to discriminate the sulfur sources. Coals contain more selenium than petroleum. The content of selenium in coals often shows more quantities than sulfur.

为了区分环境中含硫化合物的来源并探讨其行为，对化石燃料燃烧产生的源硫和空气及悬浮颗粒物中含有的环境硫进行了同位素测量。结果表明，空气中的硫主要来源于石油，悬浮颗粒物中的硫主要来源于煤。收集空气样本进行同位素测量大约需要50天，并且需要每周添加一次吸收液。本课题研究了利用活性炭纤维采集空气样品的新方法。空气样品中二氧化硫的采集效率几乎为0%。这种催收方式还可以缩短催收时间。采用红外光谱法对悬浮颗粒物的无机成分进行了简单定性分析。样品与碳和KBr混合，并在分析前进行压制。几种主要的无机成分，如硫酸盐、铵、硅酸盐等，都可以分析。同时测定了煤和石油中的硒含量，以帮助鉴别硫源。煤所含的硒比石油多。煤中硒的含量往往比硫的含量多。
