  • 摘要: 本文报导了采自珠江三角洲地区一些水体(包括澳门河口湾)的17个表层沉积物样品中多氯联苯(HCBs)的含量、分布特征的初步研究结果.结果表明:①分布于五个地区的17个表层样品中PCBs的含量以广州市附近的样品含量最高,澳门内港次之,分别为485.45μg·kg-1和338.53μg·kg-1,其余样品均比广州、澳门低一个数量级,而且从珠江干流上游至下游,PCBs含量具有明显降低的趋势;②广州工业区和澳门内港样品的PCBs组成有明显的差别.③广州和澳门样品已受到PCBs污染.
    Abstract: This work presents preliminary results on the concentration of polychlorinated biphenyls (PCBs) and its distribution and characterization of PCB congeners in surface sediments collected in March, 1997 at 17 locations from Pearl river delta and Macao estuarine. The distribution pattern of various samples are discussed.The order of PCBs concentration in the sediment sample as: Guangzhou Macao Shiziyang -West river - lingdingyang - Pearl river estuarine.Each concentration is : Guangzhou 485.45 ng·g-1, Macao 338.53 ng·g-1, Shiziyang 25.4ng-1·g-1, West river 13.13ng·g-1 and Lingdingyang 11.46ng·g-1 and Pearl river estuary 11.86 ng·g-1 dry weight. The distribution pattern of PCB congeners in samples. From Guangzhou and Macao indicated that the PCBs of Guangzhou come from industry mixture of Aroclor 1260, but that of Macao from Aroclor 1254 and Aroclor 1260. The PCBs concentration in samples collected from Pearl river suggested that the concentration decreased from the upper to lower reaches of the Pearl river with increasing distances from industry area.
