【摘要】 持久性有机污染物(Persistent Organic Pollutants,POPs)是指具有毒性、生物蓄积性和半挥发性,在环境中持久存在的,且能通过空气、水和迁徙物种作长距离迁移并沉积在远离其排放地点的地区,对人类健康和环境造成严重危害的有机化学污染物质,其中大气传输是POPs长距离传输的主要途径之一。在全球格局中,中国即是污染物的源之一,但同时也是污染物的汇。所以源汇关系研究很重要。为了系统地开展POPs通过大气传输的源汇关系的研究工作,我们需要解决三个方面的问题,(1)建立POPs排放清单;(2)测量POPs在各环境介质中,特别是大气和土壤的含量;(3)模拟POPs物质在大气中的传输及迁移规律。本文将介绍国际上开展POPs通过大气传输的源汇关系的研究工作的动态,并对我国这方面工作的开展作一些介绍和展望。更多还原

【Abstract】 Persistent Organic Pollutants, (POPs )are organic chemicals that are toxic, persist in the environment, accumulate in high concentrations in fatty tissues and are bio-magnified through the food-chain, and have a potential for long-range environmental transport to a receiving environment in locations distant from the sources of their release through air, water or migratory species, among which, atmospheric long-range transport is the major pathway for most POPs. As one of the largest countries in the world, being one of the sources for the global pollution by some of these POPs, is also one of the sinks of some POPs released outside of China. Thus it is important to understand the relationship between the sources and the acceptors for POPs in China. In order to do so, three major elements are needed to be studied: (1) to compile emission inventories of POPs, (2) to monitoring pollution level of POPs in all compartments, especially in air and soil, and (3) to simulate the transport of POPs in air by using transport models. In this paper the progress of the research in the world on the relationship between sources and acceptors of POPs due to atmospheric transport is reviewed, and our work in China in this area is also introduced.更多还原
