Marmara Denizi güneyi (Kocasu Deltası) sedimanlarında ağır metal kirliliğinin araştırılması

Abstract

Sea of Marmara (Kocasu Delta)  Heavy metal accumulation and its spatial distribution  Pollution assessment and possible sources Figure A. Nickel(Ni), Chromium (Cr) and Lead (Pb) Multi-element Distribution DiagramsPurpose: This study investigated heavy metal accumulation and its spatial distribution, the extent of the pollution and possible sources in the Kocasu Delta located at the south of the Sea of Marmara.

Element-based ecological and human health risk assessment in a lagoon system in a densely populated basin

“…Based on the spatial analysis, the likely source of moderate Pb enrichment in the MIZ is the discharge of the sea because MIZ is the region most open to the influence of the waves (Figure 2). In a study conducted on the surface sediments of the Marmara Sea on the northern shores of the Karacabey floodplain, Pb enrichment was found to be at low/ moderate level due to the anthropogenic activities carried out in the Susurluk basin and its lithological characteristics (Pehlivan, 2017). The literature on the subject and spatial analysis strengthen the possibility that the source of Pb enrichment is seawater intrusion (Pehlivan et al, 2021).…”

The literature on the subject and spatial analysis strengthen the possibility that the source of Pb enrichment is seawater intrusion (Pehlivan et al, 2021). Zn, which was found to be moderately enriched around the MIZ, is an important plant nutrient.…”

“…In a previous study conducted on the coasts of Kocasu Delta, it was determined that Ni, Pb and Cr caused low to moderate pollution. The possible sources of Ni, Pb and Cr were identified as lithological characteristics in the Susurluk Basin and discharge partly from anthropogenic activities (Pehlivan et al, 2021). Ni, As and Cr are predicted to have common, but naturally and anthropogenically complex sources.…”

“…Ni was determined to cause a carcinogenic health risk at all sampling points; As caused a carcinogenic health risk in the WZ by exceeding the tolerable limit in the sea facing-parts of the SCZ (at ST 2, ST 16, ST 17 and ST 18); and Cr caused a carcinogenic health risk (Table 4). Another study determined that the volcanic rock formations and regional anthropogenic effects in the Susurluk basin, where the Karacabey floodplain is located, increased the Ni and Cr concentrations (Pehlivan et al, 2021). Statistical analysis placed As in the same element group.…”

“…Magmatik kayaçlarda ortalama Cu içerikleri, ultrabaziklerde 10 ppm, bazaltiklerde 87 ppm, granitik kayaçlarda 10 -30 ppm ve siyenitlerde 5 ppm'dir. Sedimanter kayaçlarda ortalama olarak şeyllerde 45 ppm, yerkabuğunda 55 ppm'dir (Turekian ve Wedepohl, 1961;Krauskopf, 1985;Pehlivan, 2017).…”
