Abstract

The finest sediment group (FSG) including (Ø₃, Ø₄ and <Ø₄) and the bulk sediment samples were used to estimate the leachable forms of Fe, Mn, Zn, Cu, Ni, Pb, Co and Cd at Adabiya and El Zaitiya harbours in the Suez Bay at the northern tip of Suez Gulf using flame atomic absorption spectrophotometer (AAS). FSG was representing the essential constituents of the seafloor sediments with averages of 70.62% from the total sediments at El-Zaityia Harbour and 70.38% at Adabiya Harbour indicating the deposition under calm oceanographic conditions. Fe was the metal carrier for the different heavy metals, the average leachable forms of Fe and Zn in the FSG (50924.94; 377.61 µg/g) about two folds in the bulk sediment (27153.9; 180.47µg/g) at El Zaityia Harbour and about three folds in the FSG (43965.42; 456.94 µg/g) which more than the bulk sediments (17777.75; 134.62 µg/g) at Adabiya Harbour. In the same Matter, the averages of leachable forms of Mn, Cu, Ni and Pb in the FSG recorded about three folds (532.15; 195.38, 54.60, 145.94 µg/g) at El Zaitiya Harbour and (476.88; 109.42, 47.35, 67.11 µg/g) Adabiya Harbour than the recorded averages in the bulk sediment (182.43; 67.01, 19.01, 62.80 µg/g) at El Zaitiya Harbour (155.56, 35.14, 15.78, 20.27 µg/g) and Adabiya Harbour respectively.
