Field monitoring of the toxic organic compounds (PCBs, PAHs, organochlorine pesticides) in the top sediments of Pearl River Estuary and its up-streams were made. It was found that the highest concentrations of these toxic organic compounds occurred in the sediment sampled at Macau inner harbor (ZB013), which is a sink of suspended fine particles transported from the upstream waterways. Because of the affinity of the hydrophobic organic compounds (PAHs, PCBs) for the solid phase, these fine particle depositions led to accumulation of these compounds in the sediment of Macau. The atmospheric dry deposition may be another source of the toxic organic pollution in the sediment.
对珠江河口及其上游表层沉积物中的有毒有机化合物（多氯联苯、多环芳烃、有机氯农药）进行了实地监测。结果发现，这些有毒有机化合物的最高浓度出现在澳门内港采集的沉积物（ZB013）中，该区域是上游水道输送来的悬浮细颗粒的汇聚地。由于疏水性有机化合物（多环芳烃、多氯联苯）对固相的亲和力，这些细颗粒沉积物导致这些化合物在澳门沉积物中积累。大气干沉降可能是沉积物中有毒有机污染的另一个来源。
