Study on Transportation and Toxic Effects of Typical PAHs in Mangrove Wetland Simulation System

Abstract

红树林生态系统是热带、亚热带海岸重要的湿地生态系统。河口海岸带生态破坏性开发活动的日益频繁和大量的工农业废水和生活污水的长期直排入近岸海域使红树林湿地遭受极大的破坏。红树林湿地生态系统因生产力高、富含有机质以及强还原性环境条件等特性,使之成为吸收和积累多环芳烃(PolycyclicAromaticHydrocarbons,PAHs)的重要场所。因此,深入开展红树林湿地中PAHs污染物的环境行为及其对红树林生境的生态效应的研究,具有重要意义。 菲(Phenanthrene,PHE)和荧蒽(Fluoranthene,FLA)分别是16种优控PAHs中3环和4环芳烃的代表性化合物,已有的文献报道在...The mangrove ecosystem, as one of the most important intertidal estuarine wetlands along tropical and subtropical coastlines, fulfills important ecosystem service functions. With the increasing development of destructive activities in coastal ecosystems, more and more industrial, agricultural wastewater and living sewage are discharging directly into offshore marine areas. Human activities have se...学位:理学博士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2122005140319
