Sr, Nd and Pb isotopic signatures and elemental pattern in surface sediments in the Elbe River Estuary in 2015@en

The Elbe River was long considered as one of the most anthropogenically impacted rivers in Europe. Its estuary is characterized by strong tidal effects, continuous dredging and dumping of sediments and intense ship traffic between the North Sea and the Port of Hamburg. These activities make the estuary a highly dynamic study area of interest to numerous parties. The aim of this study was to elucidate if a combined multi-element fingerprinting and isotopic tracer approach represents a suitable tool to investigate transport and mixing processes of inorganic contaminants within a complex and highly dynamic estuarine environment. […]易比河（Elbe River）长期以来被认为是欧洲受人类活动影响最显著的河流之一。其河口湾以强烈潮汐作用、持续的沉积物疏浚与倾倒作业，以及北海至汉堡港之间的密集船舶通航为典型特征。上述人类活动使得该河口湾成为高度动态的研究区域，受到众多科研及相关方的关注。本研究旨在阐明：多元素指纹识别技术（multi-element fingerprinting）与同位素示踪法（isotopic tracer）联用方案，是否可作为适用于复杂且高度动态的河口湾环境中无机污染物运移与混合过程研究的有效工具。[…]
