The element concentrations and enrichment factors of sediments in west marmara sea ports

Abstract

In this study, the concentration of various elements in marine sediments from Western Marmara Sea Ports has been analyzed and evaluated as well as correlated with similar studies completed earlier in the Western Marmara Sea region by using all the available data. Enrichment factor calculations made according to world average values were also calculated according to Western Marmara background values. In enrichment factor (EF) calculations EF > 3 was found in Cu and Mn calculations in M.Ereğlisi. In M.Ereğlisi, Şarköy and Menekşe the enrichment factor is 1 < EF < 3, and element enrichment is moderate or less in these regions. In the analysis EFZn > 3 in core 1–2, EfAs > 3 in core 10–13, core 14–16, core 18–19, and core 29 also EF > 3 in the enrichment factor analysis for As. In the analysis for Co is EFCo > 3 in core 8–29 samples. Ni enrichment was obtained as EFNi > 3 in core 16–29 samples and EF < 1 and 1 < EF < 3 in all other samples. In enrichment factor calculations using West Marmara Sea background values, it was calculated as EFCu > 3 in core 2 and 12, and EFMn > 3 is for core 1. In other enrichment factor calculations in ports and other locations, all elements were calculated as EF < 1 in some locations and 1 < EF < 3 in some locations. This means that there is little or moderate enrichment according to the latest data. This means that there is little or moderate enrichment in all locations. The reason for the more enrichment of Ni and Mn elements in some locations in the Western Marmara Sea is thought to be anthropogenic. © 2020 Desalination Publications. All rights reserved.
