【摘要】：珠江三角洲是我国经济最为发达的地区之一,也是环境污染问题最为严峻的地区之一。严峻的环境污染问题毫无疑问地将影响地区经济的可持续发展与人体健康。大量的研究表明,多种传统和新型的有机污染物在珠江三角洲各类环境介质、生物体、甚至人体中广泛存在。这些污染物包括多溴联苯醚(PBDEs)、多氯联苯(PCBs)、有机氯农药(OCPs)、有机磷酸酯类阻燃剂(OPEs)等。系统研究污染物的环境行为及人体暴露风险具有重要的科学和现实意义,可以为政策制定者采取有效的污染物控制措施提供科学数据支持。有机污染物在环境界面(沉积物-水、大气-水及土壤-水)迁移是控制其地球化学行为的重要过程。本文综述了珠江三角洲典型有机污染物的宏观环境行为、微观的环境界面通量测定技术、人体暴露风险三个方面的研究历史及现状,并总结了现有研究的不足,展望了研究趋势。
[Abstract]:The Pearl River Delta is one of the most developed regions in China. It is also one of the most serious environmental pollution problems. Serious environmental pollution problem will undoubtedly affect the sustainable development of regional economy and human health. A large number of studies show that. A variety of traditional and new organic pollutants are widely found in various environmental media, organisms, and even human bodies in the Pearl River Delta. These pollutants include PBDEs (polybrominated diphenyl ethers). Polychlorinated biphenyls (PCBsN), organochlorine pesticides (OCPs). It is of great scientific and practical significance to systematically study the environmental behavior of pollutants and human exposure risk. Scientific data can be provided for policymakers to take effective pollutant control measures. Organic pollutants are at the environmental interface (sediment-water). Atmospheric-water and soil-water) migration is an important process to control its geochemical behavior. This paper reviews the macroscopic environmental behavior of typical organic pollutants in the Pearl River Delta and the microcosmic environmental flux measurement techniques. The research history and present situation of human exposure risk are summarized, and the research trend is prospected.
