dc.description.abstract本次研究分析了南海区域共34个表层沉积物样品以及西北陆架区2个柱状沉积物样品中6种痕量金属元素(Cu、Pb、Zn、Cd、Cr和Ni)的含量,采用地质累积指数法、污染负荷指数法和潜在生态风险指数法对样品中的痕量金属进行污染评价,并初步探讨研究区域中重金属的来源。取得以下主要结论: 南海表层沉积物中痕量金属Cd的含量为0.02~0.86mg/kg(平均0.28mg/kg);Cu为4.08~55.87mg/kg(平均17.83mg/kg);Pb为5.03~74.57mg/kg(平均37.52mg/kg);Zn为74.67~279.33mg/kg(平均147.74mg/kg);Ni为25.92~26...
dc.description.abstractConcentrations of trace metals in sediments from the middle and north in South China Sea (SCS) and its vicinity were determined by Atomic absorption spectrometry. Heavy metals pollution assessment in sediments from the study areas were conducted by geoaccumulation index, pollution load index and potential ecological risk index. The lead isotope tracing technique was applied to discriminate the sou...
