Chlorinated hydrocarbons in zooplankton of the North Atlantic

Data on distribution of chlorinated hydrocarbons in ecosystem components of the North Atlantic, i.e. water, hydrobionts, and bottom sediments, for the period 1980-1984 are presented. Distribution char¬acteristics are considered as a function of various factors (physiographic conditions of the area, species composition of zooplankton, mineral composition of bottom sediments) for each of ecosystem components. Dis¬tribution of concentration factors of chlorinated hydrocarbons in individual hydrobionts and bottom sediments are determined. Maximal distribution coefficients are those of integral plankton samples (up to 5 orders of concentration magni¬tude).

本文收录了1980-1984年北大西洋生态系统各组分（水体、水生生物（hydrobionts）与底泥）中氯代烃（chlorinated hydrocarbons）的分布数据。针对每一类生态系统组分，本研究将其分布特征视为区域自然地理条件、浮游动物（zooplankton）物种组成、底泥矿物组成等多种因素的函数开展分析。研究测定了氯代烃在单个水生生物及底泥中的浓缩系数（concentration factors）分布情况，其中整体浮游生物样品的分布系数（distribution coefficients）最高，其浓度量级跨度可达5个数量级。
