我国酸沉降地区硫源的硫同位素组成研究

Study on sulfur isotopic composition of sulfur source in acid deposition regions in China

我国同世界大部分地区的酸雨类型一致,均为典型的硫酸型酸雨,因此硫同位素组成是示踪酸雨来源的重要手段。在前人研究的基础上,对酸雨硫同位素组成研究的思路和实验方法进行综述,重点介绍燃煤过程中硫同位素的分馏效应和大气SO2、气溶胶、大气降水、苔藓和小麦等植物中的硫同位素组成等,对环境地球化学的研究具有重要意义。

On the basis of previous studies, the authors summarized the research ideas and experimental methods of the study on acid rain, and focused on introduction of the isotope fractionation effect during the coal burning process and the characteristics of sulfur iso- topic composition in atmospheric sulfur dioxide, aerosol, precipitation, wheat, mosses and other plants.
