Monitoring of Pcdd/Fs Levels in Selected Mediterranean Fish Species Collected from The Egyptian Coastal Harbors [electronic resource].

Includes reference.

Alexandria and Port Said are two northem coastal Egyptian govemorates located along the Mediterranean Sea. Both govemorates were considered the most important harbors in Egypt. Many industrial activities located in it, especially fertilizers manufactories, recycling and waste incinerators which considered as a major source for food especially fish contamination with PCDD/rs. This study highlighted the levels of PCDDs/Fs to assess the ecological and potential health risks derived from its intake and was performed to obtain information about the concentrations of PCDDs/Fs in fish that are high in production and commonly consumed. A total number of 26 fish samples that represent different types;Tilapia (Ti/apia Zilli), grey mullet (Mugil cepha/us), sardine (Sardinella spp.) and brush tooth lizard (Saurida undosquamis) samples were collected during 2006 from seven locations along the coastal Mediterranean borders for both govemorates. The results demonstrated that the concentration of dioxins didnot exceeded the maximum level proposed by the Egyptian Organization for Standardization which relatively the same with the European Community which have set a limit of 4 pg WHO-TEQ/g of PCDD/Fs for fish and fish products on a wet weight basis. The results obtained from the analysis of seventeen 2.3,7,8substituted congeners of PCCDlFs in the four species of fish from seven areas over the Mediterranean Sea were determined and showed to be lower than the maximum permissible limits. Average concentration of total PCDD/Fs in tilapia, grey mullet. sardine and brush tooth lizard fish from the Mediterranean Sea was ranged from 0.22 to 2.9 pg WHO-TEQ/g tw, 0.38 to 1.2 pg WHO-TEQ/g tw, 0.21 to 0.47 pg WHO-TEQ/g tw, and 0.3 to 0.66 pg WHO-TEQ/g tw respectively.
