Heavy metal concentrations in surface sediments from two regions (Saros and Gökova Gulfs) of the Eastern Aegean Sea

Abstract

The main goal of this study is to determine the present heavy metal pollution state in the two gulfs of the Aegean Sea; Saros and Gökova Gulfs. The surface sediments were collected from 11 and eight locations in the Saros and Gökova during May 2001, respectively. The results showed that the sediments of Saros and Gökova gulfs were polluted with Pb, Cr, Zn, Mn, and Ni and Pb, Cr, Ni, and Mn, respectively. For various metals the contamination factor (CF) has been calculated to assess the degree of pollution in sediments. The sediments were noted to be not contaminated with Hg, Cd, and Cu in all areas. Moderate contaminations were observed for Pb, Cr, and Zn in Saros Gulf. The CF was moderate and very high for Ni in the Saros and the Gökova Gulf, respectively.

Temporal evolution of the water characteristics in the bays along the eastern coast of the Aegean Sea: Saros, İzmir, and Gökova bays

“…The oceanography of the Gökova Bay has not been studied until now. However, several studies on water masses and water quality can be found for İzmir Bay (Sayın, 2003;Sayın et al, 2006Sayın et al, , 2007 and Saros Bay (Tokat, 2006;Tokat and Sayın, 2007;Pazı, 2008;Sayın and Beşiktepe, 2010;Uluturhan, 2010).…”

“…Marine sediments provide useful information for environmental and geochemical research about marine pollution (Uluturhan, 2009). Therefore, sediments are ecologically important components of the marine environment and have been contaminated by inorganic and organic materials.…”

“…As it is known, there are so many studies on sedimentology and geochemistry of sediments in the Aegean Sea (Küçüksezgin, 2001;Dalman et al, 2006;Pekey, 2006;Uluturhan, 2009;Esen et al, 2010). Each of the scientist have been assessed one or two accumulation indexes and have been commented about that indexes results.…”

Metal partitioning in sediment pore water from the Ondo coastal region, Nigeria

“…Metals are a class of important anthropogenic inorganic pollutants and due to their various health-related problems and widespread environmental occurrences, they have garnered much attention around the world (Paulson et al 2006;Yalcin, Narin, and Soylak 2007;Lalah, Ochieng, and Wandiga 2008;Liu et al 2009;Hiller, Jurkovic, and Utriepka 2010;Uluturhan 2010). Certain trace elements, Cr, Cu, Ni, and Zn, are essential micronutrients required for the normal growth and function of organisms.…”

“…Certain trace elements, Cr, Cu, Ni, and Zn, are essential micronutrients required for the normal growth and function of organisms. Other trace elements like Cd, Hg, and Pb are considered toxic with respect to human health and aquatic life (Uluturhan 2010). In aquatic ecosystems, sediments are the main sink for these metals but when environmental conditions change (pH, redox potential, particle size, etc.…”
