“…Studies on chemical partitioning of element concentrations in the bay sediments are lacking until now. Most of the studies conducted on the bay sediments concentrated only on few trace elements [10][11][12][13][14][15][16] and no published data are available for Se, As, Co, and Hg. The most comprehensive study on the trace element pollution in sediments of the bay was performed by EL-Sokkary, [14] more than a decade ago.…”

Sediment samples were collected from 30 different locations in Abu Qir Bay (Mediterranean Sea), East Alexandria, Egypt and analyzed for trace elements. The highest concentrations of most of the elements were observed in the nearshore stations in the vicinity of the major anthropogenic activities as industrial settlements, wastewater discharges, and agricultural drainage. In addition, mussel samples of Mactra corallina and Tapes decussata were collected corresponding to the sediment samples. Concentrations of As, Cd, Cr, Mn, and Zn in the mussel tissues were higher than concentrations in sediments, thus indicating their relatively high bioavailability. Sequential extraction procedure was performed on selected sediment samples. Significant correlations were observed between the concentrations of Cu, Mn, Pb, and Zn in the exchangeable fraction of the sediments and the corresponding tissues of M. corallina. The output of the risk assessment applied on the sediments revealed that adverse ecological effects to benthic species could occur and that a higher level of risk is expected from the exposure to Cd, Cr, Hg, and Zn. No adverse carcinogenic or noncarcinogenic human health effects are expected from the consumption of the two mussel species from Abu Qir Bay.
