Abstract
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.
