摘要

该研究的范围是评估Cu、Zn、Co、Ni和Cr的潜在来源对波罗的海东南部俄罗斯部分海底沉积物的影响。共采集68个样品，并对其粒度（激光衍射和筛分法）和重金属浓度（原子吸收光谱法）进行分析。为了避免细粒沉积物对污染物积累的吸附能力的影响，采用了重金属浓度对Fe的归一化。计算了环境指标（污染因子和修正污染程度）。研究表明，石油平台、管道、港口和污水处理设施对海底沉积物地球化学组成的贡献。作者已经确定，由于污染物的沿岸运输，库伦和维斯瓦河中部的重金属污染水平。

Heavy metals contamination of the sediments of the south-eastern Baltic Sea: the impact of economic development

The scope of the study was to assess the impact of potential sources of Cu, Zn, Co, Ni, and Cr on bottom sediments of the Russian sector of the south-eastern Baltic Sea. A total of 68 samples were taken and analyzed for grain-size (laser diffraction and sieve method) and heavy metal concentration (atomic absorption spectroscopy method). To avoid the influence of the sorption capacity of the fine-grained sediments to accumulate the pollutants, the normalization of the heavy metal concentration to Fe was applied. The environmental indices (contamination factor and modified degree of contamination) were calculated. The research has shown the contribution of oil platform, pipelines, ports and wastewater treatment facilities on the geochemical composition of bottom sediments. The authors have identified the level of heavy metals contamination of the middle parts of the Curonian and Vistula spits as a result of alongshore transport of pollutants.

期刊介绍： BALTICA is an international periodical journal on Earth sciences devoted to the Baltic countries region and the Baltic Sea problems. This edition as a Yearbook is established in 1961 by initiative of Academician Vytautas Gudelis. Since 1993, an Editor-in-Chief of the journal became Academician Algimantas Grigelis. BALTICA is published biannually (in June and December) in cooperation with geoscientists of the circum-Baltic States. BALTICA is publishing original peer-reviewed papers of international interests on various Earth sciences issues. The particular emphasis is given to Quaternary geology, climate changes and development of ecosystems, palaeogeography, environmental geology, as well as stratigraphy, tectonics, sedimentology and surface processes with relevance to the geological history of the Baltic Sea and land areas. Journal emphasizes modern techniques, methodology and standards. The journal structure comprises original articles, short reviews, information, bibliography.
