Öğe The heavy metal pollution level and risk assessment in marine gastropods of sediments of the red sea coast(Taylor and francis ltd., 2024) Hamed, El Sayed A. E.; Uosif, M. A. M.; Khalifa, Moataz M.; Elgendy, Ahmed R.; Abbasi, A.; Awad, Hamdy A.; Ene, Antoaneta; Zakaly, Hesham M. H.The bioaccumulation of heavy metals and their distribution in the bivalves Conomurex fasciatus and sediments samples were investigated in Safaga (the Red Sea) by means of an atomic absorption spectrometer. The findings reveal that the bivalves had a significant propensity to absorb metals like Fe, Cu, Zn, and Pb. When the weight of soft tissues was compared to the overall weight of the bivalves and trace metal concentration, it was discovered that the essential metals Mn and Cu and the trace metals Zn and Ni were bioaccumulated in the mollusks as a function of their body weight. Contamination with these metals was quantified using the contamination factor (Cf), enrichment factor (Ef) and geo-accumulation index (Igeo). The weathering process of surrounding beaches, paint, oil, sewage, and transportation are considered the primary causes of anthropogenic pollution with heavy metals. Heavy metals from human and terrestrial sources can infiltrate the marine ecosystem.
