Report: Macrozoobenthos: Heavy metals in shellfish and bristleworms — Norderney (1991/1992)»

The present work presents first results on heavy metals (Pb, Cd, Cu and Zn) in 8 selected species of soil fauna (Cerastoderma edule, Mytilus edulis, Macoma balthica, Nephtys Hombergii, Nephtys cirrosa, Arenicola marina, Nereis diversicolor and Scolelepis squamata). The aim of this biomonitoring study is to obtain information about the different bioavailability of the environment via concentrations of substances in organisms. The material was partly obtained in the wattage near Norderney, partly on the seaside beach of the island. In this paper we report preliminary results of heavy metals (Pb, Cd, Cu and Zn) in 8 selected macrobenthic species (Cerastoderma edule, Mytilus edulis, Macoma balthica, Nephtys Hombergii, Nephtys cirrosa, Arenicola marina, Nereis diversicolor and Scolelepis squamata). Within the concept of biomonitoring, chemical concentration levels in organisms are considered as indicators of the bioavailable fraction of substances in the environment. Samples were partly taken in the Wadden-sea of Norderney, partly at the exposed sandy beach of the island.本研究首次报道了8种选定大型底栖动物（macrobenthic species）体内重金属的检测结果，所涉重金属包括铅（Pb）、镉（Cd）、铜（Cu）及锌（Zn），所涉物种分别为Cerastoderma edule、Mytilus edulis、Macoma balthica、Nephtys Hombergii、Nephtys cirrosa、Arenicola marina、Nereis diversicolor及Scolelepis squamata。本生物监测（biomonitoring）研究旨在通过测定生物体内的物质浓度，获取环境中不同物质的生物可利用性（bioavailability）相关信息。实验样品部分采自诺德尼岛（Norderney）附近的瓦登海（Wadden Sea）潮间带滩涂，部分采自该岛的海滨沙滩。 本文同时报道了上述8种大型底栖动物体内重金属的初步检测结果。基于生物监测的研究理念，生物体内的化学物质浓度可作为环境中对应物质生物可利用组分的指示指标。本次研究的样品部分采集自诺德尼岛周边的瓦登海海域，部分采集于该岛的裸露沙滩区域。
