研究了受有色金属冶炼污染严重的锦州湾浅层沉积物中Cd、Cu、Pb、Fe和Mn的分布形态。沉积物中Cd、Cu和Pb的浓度分别高出国家标准（GB 18668-2002） 100倍、13倍和7倍。顺序萃取试验表明，沉积物中Cd的交换组分占39% ~ 61%，表明沉积物中Cd对当地环境具有较高的风险。而铜和铅处于中等危险水平。根据金属形态百分比与总金属浓度的关系，认为在污染物迁移过程中，部分地球化学组分中Cd、Cu和Pb的分布是动态的，金州湾沉积物中金属的稳定性按照Pb > Cu > Cd的顺序递减。
This work investigated the distribution and speciation of Cd, Cu, Pb, Fe and Mn in the shallow sediments of Jinzhou Bay, Northeast China, which has been heavily contaminated by nonferrous smelting activities. The concentrations of Cd, Cu and Pb in sediments were found to be 100, 13 and 7 times, respectively, being higher than the national guideline (GB 18668-2002). Sequential extraction test showed that 39%–61% of Cd were exchangeable fractions, indicating that Cd in the sediments posed a high risk to local environments. While Cu and Pb were at moderate risk levels. According to the relationships between percentage of metal speciation and total metal concentration, it was concluded that the distributions of Cd, Cu and Pb in some geochemical fractions were dynamic in the process of pollutants migration and the stability of metals in sediments of Jinzhou Bay decreased in the order of Pb > Cu > Cd.
