摘要
重金属污染是大气降尘污染的一个重要方面,治理污染首先要查明污染源。文章概述了近几年来国内外大气降尘重金属污染源解析的常用方法及其研究方法中的一些特点,重点阐述了铅、锶同位素示踪技术在大气降尘中重金属污染溯源研究中的应用,针对以往研究工作的不足和存在的问题,指出了今后重金属污染源解析研究中的重点:采用Pb、Sr同位素示踪法结合元素地球化学追踪重金属污染源和评价污染程度;利用Pb、Sr同位素示踪技术研究大气降尘重金属污染物的迁移转化规律。
Heavy metals in atmospheric dust can cause many problems of serious pollution. It is very important to find the contamination source before we deal with the pollution. The research methods of recognizing and analyzing the sources of heavy metals in atmospheric dust, as well as some characteristics of recent research methods, are summarized in this paper. And the applications of tracer techniques of isotopes such as Pb and Sr, and of radionuclides in research on the recognition of sources of heavy metals are emphasized. On account of the deficiency in the past studies and the existing problems, we have put forward the key points involved in the study of how to recognize and analyze the heavy metal contamination sources in the future, including how to trace the contamination source and assess the pollution extent so as to reveal the transference and transformation laws of heavy metals in atmospheric dust, using the Pb, Sr isotope tracing techniques.
