Vertical Distribution of Persistent Organic Pollutants in the Core Sediments from Beach Bath in Tanggu District of Tianjin

  • 摘要: 应用GC-MS对渤海湾潮间带天津塘沽海滨浴场沉积物中的多环芳烃、有机氯农药、多氯联苯和多溴联苯醚等持久性有机污染物的垂直分布进行了研究.4类污染物的污染水平依次为PAHs>OCPs>PCBs>PBDEs,其质量分数范围分别为113.1~1 040.0和7.6~118.1 ng/g,715.0~7 048.3和10.0~158.2 pg/g(以干质量计). 在0~50 cm深度,w(PAHs)相对较高且变化较大,50 cm以下深度,w(PAHs)逐渐降低且变化较小.在测定的16种PAHs中w(菲)最高,并随深度的增加而降低.污染源解析表明,PAHs的污染主要来自石油输入和煤、木炭等的燃烧. OCPs的垂直分布与PAHs类似,在定量的20种OCPs中,w(HCB)最高,其次是w(HCHs)和w(DDTs);研究表明HCHs和DDT没有新的输入. 在0~70 cm深度,w(PCBs)低且变化小,70~80 cm深度突增1个数量级. w(PBDEs)较w(PCBs)低1个数量级,在5~10 cm深度污染水平最高.
