An ecological risk investigation of marine sediment from the northern Mediterranean coasts (Aegean Sea) using multiple methods of pollution determination

摘要: The aim of this study is an assessment metal pollution levels in Aegean Sea sediment. Sediment samples collected from 7 different locations (Yenikoy, Edremit, Ayvalik, Dikili, Aliaga, Hekimadasi, and Ildir) along the northern Mediterranean region Turkey were investigated for 11 elements (Cu, Fe, Zn, V, Cd, Ni, As, Pb, Mn, Co, Cr). Graphite furnace atomic absorption spectrophotometry (GFAAS) flame (FAAS) used elemental analysis. findings evaluated with sediment methods by taking two values as a reference then investigating adverse biological effects profiles on living organisms. Cr concentrations within moderate to significant range terms contamination factor $$ \Big({C}_f^i $$ ), albeit varying according location. most problematic regarding enrichment (EF) was Ayvalik Cu, Cd. However, EF, anthropogenic effect not at alarming level. This further supported results geoaccumulation index (Igeo). modified degree (mC d ) load (PLI) suggested that accumulation greatest least Hekimadasi Ildir. location highest total toxic unit (ΣTU) Edremit. existing element profile organisms 21% when mean range–median quotient (m-ERM-q) considered. As Ni all stations found be higher than threshold level (TEL) Effect Range Low (ERL). Edremit exceeded probable (PEL) Median (ERM). Toxic (TU) these ranged 59.30 80.43%.
