| 摘 要： | 沉积物-水界面是自然水体在物理、化学和生物特征等方面差异性最显著的环境边界,界面及附近发生的物理和化学反应,如吸附和解吸、迁移和转化、扩散和掩埋以及生物扰动等作用是控制和调节水体和沉积物之间物质输送和交换的重要途径.持久性有机污染物由于其具有致癌、致畸、致突变及内分泌干扰作用而受到人们的广泛关注,它们在沉积物-水界面的...

| Abstract: | ediment-water interface is an environmental boundary with the greatest distinction in physical,chemical and biological characteristics in natural water,responsible for transport and exchange of chemical species between water and sediment.The factors which affect the migration of persistent organic pollutants(POPs) across the sediment-water interface are briefly summarized in this paper.The roles of physical resuspension and bioturbation in the transport of POPs at the sediment-water interface are also revie... |
