The arctic regions are facing serious environmental threats related to global warming. The marine geochemistry and metal sequestration in the marine sediments imply the present as well as past climatic conditions and elemental distribution, along with its dynamics. Various geochemical parameters were measured in the twelve sediment samples from Kongsfjorden. These were dominated by sand in the inner fjord and clay in the outer fjord area. The geochemical parameters such as organic carbon (OC) (mean 1.29%), inorganic carbon (CaCO₃) (mean 10.16%), total nitrogen (TN) (mean 0.19%) and total phosphorus (TP) (mean 0.08%) show higher concentrations in the surface sediments of outer fjord regions. The concentrations of heavy metals are higher in the outer fjord regions and lower in the inner fjord regions. The various sediment quality-based indices analyses, such as the Enrichment Factor (EF) and geo-accumulation index, revealed high enrichment of heavy metals like Cu, Pb, Zn in the Kongsfjorden region, which is exposed to impending pollution from various sources. The modified PERI index values indicated that outer fjord region was under the level of considerable risk.

北极地区正面临与全球变暖有关的严重环境威胁。海洋沉积物中的海洋地球化学和金属螯合意味着当前以及过去的气候条件和元素分布及其动态。在来自Kongsfjorden的十二个沉积物样品中测量了各种地球化学参数。这些以内峡湾的沙子和外峡湾区域的黏土为主。地球化学参数，例如有机碳（平均1.29％），无机碳（CaCO ₃）（平均10.16％），总氮（TN）（平均0.19％）和总磷（TP）（平均0.08％）在外峡湾地区的表层沉积物中浓度较高。重金属的浓度在外峡湾区较高，而在内峡湾区较低。各种基于沉积物质量的指标分析，例如富集因子（EF）和地质积累指数，都显示了Kongsfjorden地区重金属如Cu，Pb，Zn的高度富集，暴露于各种来源的即将来临的污染。修改后的PERI指数值表明，外峡湾地区处于相当大的风险水平之下。
