本次研究分析了北极王湾与南极菲尔德斯半岛及附近区域共59个表层沉积物和土壤样品以及新奥尔松地区1个柱状沉积物样品中5种重金属元素（Cu、Pb、Zn、Cd和Cr）的含量，采用地质累积指数法和潜在生态风险指数法对样品中的重金属进行污染评价，并初步探讨研究区域中重金属的来源。取得以下主要结论： 王湾及附近区域表层沉积物中重金属Cu的含量为9.84~36.33mg/kg；Pb为1.53~11.21mg/kg；Zn为46.20~159.05mg/kg；Cd为0.04~0.24mg/kg；Cr为6.05~49.56mg/kg。除了Zn外，其它重金属元素含量均明显低于全球页岩均值。地质累积指数法和潜在生态. Concentrations of heavy metals in sediments and soils from Kongsfjorden, Ny-Ǻlesund, Fildes Peninsula and its vicinity were determined by Atomic absorption spectrometry. Heavy metals pollution assessment in sediments and soils from the study areas were conducted by geoaccumulation index and potential ecological risk index. The main conclusions were as following: Heavy metal concentrations in. 学位：理学硕士 院系专业：海洋与环境学院海洋学系_海洋化学 学号：22420081151469
