Environmental Assessment of Heavy Metals Contamination of Bottom Sediments of Oman Gulf, United Arab Emirates

El Tokhi M, Amin BM* and Alaabed SA

To investigate the bottom sediments pollution characteristics and environmental assessments, twenty three samples were collected from Khor Kalba, Fujairah, Khor Fakkan and Dibba coastal areas, Oman Gulf, United Arab Emirates (UAE). The concentrations of copper, zinc, lead, iron, manganese, chromium, arsenic nickel, cobalt, cadmium, molybdenum and vanadium are varied between (9.00, 17. 15 , 11.62, 19812.8, 254.85, 156.57, 15.14, 497.46, 24.46, 5.02 and 19.40 ppm) respectively were obtained using Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) at Geology Departments, UAE University. The levels of all heavy metals in all 23 samples collected do not exceed the safety limits set by the Dutch guidelines except of Ni. The levels of heavy metals enrichments in the bottom sediments were determined using contamination indices: the Contamination Factor (CF), Enrichment Factor (EF), Geo-accumulation Index (Igeo), and Pollution Load Index (PLI). Geochemical analysis of the study area could be considered lightly or no polluted by heavy metals. This indicating a clear pattern of anthropogenic impact on Oman Gulf.
