摘要
酸雨是目前人类所面临的主要环境问题之一。世界大部分地区为硫酸型酸雨,硫同位素的示踪研究对于探讨酸雨的来源与酸雨的治理具有重要的意义。本文论述了酸雨的不同硫源(人工成因硫、生物成因硫、远距离硫)的硫同位素组成特征;从煤的硫同位素组成、大气降水的硫同位素组成和小麦等植物的硫同位素组成等三方面来论述了酸雨来源的硫同位素示踪意义。
At present, acid rain is one of the most serious environmental problems in the world. Because in most regions of the world, acid rain is of sulphuric acid type, the study of sulfur isotopic tracing can help us find the sulfur source and have important significance for research on how to control acid rain. This paper illustrates the characteristics of sulfur isotopic composition. Three sulfur origins of acid rain in these regions are recognized： anthropogenic sulfur, bioorganic sulfur, and far-transport sulfur. This paper introduces the significance of sulfur isotopic tracing in tree aspects. They are sulfur isotopes in coals, sulfur isotopic composition of surface water and sulfur isotopic tracing in plants, such as wheat and so on.
