For the basic investigation of "Acid Rain" the discrimination of the sources of sulfur or nitrogen compounds in the environment is required. This project is based on the isotopic measurement of sulfur to discriminate the sources of sulfur compounds in the environment. As the first step the isotopic measurement of sulfur in coals and petroleum which are the main anthropogenic sources of sulfur compounds in the environment was carried out. Their delta^<34>S values are less compared to that of seawater sulfate which is the main natural source of sulfur. Sulfur isotopic measurement of many kinds of environmental samples such as air, suspended particule matters, rain, snow, tree leaves, foods and human nails. Their delta^<34>S values are compared to those of fossil fuels and seawater sulfate. It becam clear that the delta^<34>S values of environmental samples reflect those of sources. The most important result of this project is that the use of delta^<34>S values of tree leaves is possible to estimate the source of sulfur in the environment.

为开展酸雨的基础研究，需要对环境中硫化物和氮化物的来源进行鉴别。本项目是基于硫的同位素测量来鉴别环境中硫化合物的来源。首先对环境中硫化物的主要人为来源煤和石油中的硫进行了同位素测量。它们的δ ^<34>S值小于作为硫的主要天然来源的海水硫酸盐。多种环境样品的硫同位素测量，如空气、悬浮颗粒物、雨、雪、树叶、食物和人的指甲。将它们的δ ^<34>S值与化石燃料和海水硫酸盐进行了比较。很明显，环境样品的δ ^<34>S值反映了源的值。该项目最重要的结果是，利用树叶的δ ^<34>S值可以估计环境中硫的来源。
