Evaluation of ecological risk, source, and spatial distribution of some heavy metals in marine sediments in the Middle and Eastern Black Sea region, Turkey

Abstract

In the present study, the concentration levels of heavy metals such as Mn, Fe, Ni, Cu, Zn, Cr and Pb in sediment samples collected from 16 sampling locations in the Middle and Eastern Black Sea regions, Turkey was measured using energy dispersive X-ray fluorescence spectroscopy (EDXRF). Various pollution parameters and methods, such as the enrichment factor (EF), geo-accumulation index (Igeo), contamination factor (CF), pollution load index (PLI), ecological risk index (RI), and geo-spatial distribution patterns were used to assess in detail the pollution status, ecological risks and sources of metals in sediment.

A holistic approach to the assessment of heavy metal levels and associated risks in the coastal sediment of Giresun, southeast Black Sea

“…Likewise, the average levels of Cr, Ni and As are higher in both Bohai Bay in China and Göcek Bay in Turkey [ 27 , 28 ]. Two recent studies conducted in the near region mid Black Sea, Turkey recorded higher levels of Cr, Ni, Cu, and Fe in one, and Fe, Zn, Cu, Cd, Pb, and As in the other, greater than the present study [ 29 , 30 ]. The average concentrations of Al, Mn, As, Cd, and Pb levels were higher in marine sediments in the Pozzuoli Gulf of Southern Italy while the rest of the HMs levels were lower than the present study [ 31 ].…”

Investigation of Microplastic Accumulation in Horse Mackerel (Trachurus mediterraneus) Caught in the Black Sea

“…Six nations border the semi-enclosed Black Sea, including Bulgaria, Georgia, Romania, Russia, Ukraine, and Türkiye (Apaydın et al, 2022). Although it receives water from significant rivers like the Danube, Dnieper, and Don, the Black Sea is susceptible primarily to anthropogenic pollution from rivers, including those from industry, marine, agriculture, household, tourism, and fishing activities (Bat et al 2022;Eryaşar et al, 2022).…”
