Recently, within the framework of European directives, the importance of marine monitoring programs has increased. In this study, a dense sampling grid was applied for a detailed assessment of the metal contents of surface sediments and suspended particulate matter from the Jade Bay, one of the tidal basins in the southern North Sea. The local lithogenic background was defined and compared with average shale, a common reference material. Based on the calculated non-lithogenic fraction and a cluster analysis, the metals are distributed in two groups: (i) elements of mainly natural origin (Co, Cr, and a major portion of Cd) and (ii) elements associated with anthropogenic activity (As, Cd, Cu, Ni, Pb, Sn, and Zn). However, even the metals of the second group are enriched by at most a factor of two relative to the local background, suggesting minimal anthropogenic impact. Spatial distribution maps show that the harbor area of Wilhelmshaven may be a particularly important source of metal.
最近，在欧洲指令的框架内，海洋监测计划的重要性有所增加。在这项研究中，应用了密集的采样网格，以详细评估 Jade 湾（北海南部潮汐盆地之一）的表层沉积物和悬浮颗粒物中的金属含量。该地区的岩石成因背景已被确定，并与常见的参考物质平均页岩进行了比较。基于计算得出的非岩石成因部分和聚类分析，这些金属分为两组：（i）主要源自自然的元素（Co、Cr 和大部分 Cd）和（ii）与人为活动相关的元素（As、Cd、Cu、Ni、Pb、Sn 和 Zn）。然而，即使是第二组金属，与当地背景相比最多富集了两倍，表明人为影响很小。空间分布图显示，威廉港的港区可能是金属的一个特别重要的来源。
