摘　　要：大气汞循环演化对全球汞的生物地球化学循环起着极其重要的作用。人为活动(化石燃料燃烧、水泥生产、氯碱制造以及金属冶炼与加工等)已成为大气汞的重要来源。在一定条件下,大气中的汞会发生干湿沉降而对某一局部环境——受体产生很大的影响。大气汞沉降在城市和工业区呈现出很强的空间梯度现象,排放源附近的汞沉降量明显较强。利用对受体的研究开展大气汞的源解析工作,是大气汞研究的一个重要领域。本文综述了污染物源解析的受体模型的研究及应用,介绍了化学质量平衡法、因子分析法、正交矩阵因子分解法、多元线性回归法等方法,概括了源解析在大气汞方面的应用成果,对我国区域大气汞源解析受体模型的建立及应用进行了探讨。The behaviors of mercury in atmosphere play a significant role in global mercury biogeochemical cycling,while anthropogenic activities,such as fossil fuel combustion,cement production,chlorine-alkali cell manufacturing,and iron-steel processing have been the main sources of atmospheric mercury.Under definite conditions,the atmospheric mercury can be dry-or wet-deposited,giving greater effects on certain local environments （receptors）.For example,significant spatial mercury deposition gradients are observed in urban and industrial areas,and larger amount of mercury deposition appears nearby the anthropogenic sources.Therefore,using a multi-element tracer approach to analyze the sources of atmospheric mercury becomes a main field in atmospheric mercury study.This paper described the development of receptor models for the source analysis of pollutants,and summarized the achievements of the application of source-receptor models in atmospheric mercury study.The establishment and application of source-receptor models in analyzing the atmospheric mercury in China were proposed.
