摘要

摘要: 通过分析长江口最大浑浊带潮周期内定点采集的悬浮物重金属Zn、Pb、Cd、Co和Ni的含量,研究了潮周期内悬浮物重金属含量分布特征和通量及其影响因素。结果表明:5种重金属潮周期内含量均值的大小顺序为:Zn> Ni> Pb> Co> > Cd。潮周期内重金属含量分布特征为:落潮平均含量高于涨潮平均含量;近岸11号站,受附近垃圾处理场污染物排放的影响, Zn和Ni涨潮平均含量高于落潮平均含量;远岸10号站,受海源物质的影响, Cd涨潮平均含量高于落潮平均含量。潮周期内,悬浮物携带的5种重金属主要向东北偏东方向输运,主要为陆源,大部分随悬浮物沉降在11-10号之间的区域。受海源物质的影响,悬浮物中的Cd通量变化相对较小,且输运方向受涨潮流的影响而改为西北向。重金属来源、水体盐度、悬浮物浓度是影响潮周期内悬浮物重金属含量分布的主要因素。Zn、Pb、Co和Ni的含量与海水盐度成正相关,与悬浮物浓度成负相关。受海源物质的影响,Cd的含量与海水盐度和悬浮物浓度的相关性不明显。

Abstract: In order to discuss the content distributions and fluxes of heavy metals in suspended matters during a tidal cycle in the turbidity maximum around the Changjiang (Yangtze) Estuary, the contents of heavy metals (Zn, Pb, Cd, Co and Ni) have been analyzed. During a tidal cycle, the average contents of heavy metals are in the order of Zn >Ni >Pb >Co >>Cd. The average contents in ebb tide are generally higher than that in flood tide. However, at the inshore Sta. 11, influenced by the contamination from the nearby waste treatment plant, the average contents of Zn and Ni in flood tide are higher than those in ebb tide and at the offshore Sta. 10, the content of Cd in flood tide higher than that in ebb tide due to marine-derived materials. The five heavy metals, mainly terrigenous, are transported towards east-northeast, and settle down with suspended matters in the area between Sta. 11 and Sta. 10. Influenced by marine-derived materials, the flux value of Cd does not alter significantly with obviously changing in flux direction towards northwest. The source of heavy metals, the salinity of water and the concentration of suspended matters are the main factors controlling the content distributions of heavy metals during a tidal cycle. There is a positive correlation between the contents of heavy metals (Zn, Pb, Co and Ni) and the salinity of water, while the opposite correlation between the contents and the concentrations of suspended matters. Because of marine-derived materials, the content of Cd is not correlated with the concentration of suspended matters and the salinity of water.
