Última distribution of phosphorus fractions and some of heavy metals in surface sediments of burullus lagoon and adjacent mediterranean sea OceanDocs Radwan, A.M.; Khalil, M.K.; El-Moselhy, K.M.. Twelve samples were collected from the surface sediments of lagoon and adjacent Mediterranean Sea. Samples were analyzed for grain size, total organic carbon (TOC), total carbonate (CaCO3), various forms of phosphorus and heavy metals (Fe, Mn, Zn, Cu, Ni, Co, Cd and Pb). The results indicated that the sediments were composed of sand, silt and clay enriched with carbonate (1.95 – 34.1%) and total organic carbon (0.06 and 3.62%). The total-P content ranged between 58 and 1186 μg/g, and the fraction associated with apatite minerals (PHCl) was the dominant (it constitutes about 50 – 73% of TP) implying that it was the main storage of phosphate. The various P phases demonstrated significant positive correlation with mean size, silt, clay, TOC, CaCO3 and TP,...

Ano: 2007 URL: http://hdl.handle.net/1834/1888 Bioaccumulation of mercury in some marine organisms from Lake Timsah and Bitter Lakes (Suez Canal, Egypt) OceanDocs El-Moselhy, K.M.. The present work is devoted to determine the level of total mercury in the different tissues of fish Mugil seheli, crab Portunus pelagicus, shrimp Metapenaeus stebbingi, and bivalves Paphia undulata and Gafrarium pectinatum collected from Lake Timsah and Bitter Lakes during spring 2003. In addition, factors affecting the accumulation of mercury in these organisms were studied. Levels of Hg in the edible parts of the investigated organisms showed the ranges 2.62 – 25.45 and 0.94 – 7.94 ng/g wet wt. in fish, 16.02 – 117.26 and 9.86 – 64.18 ng/g wet wt. in crab, 4.55 – 14.67 and 5.76 – 15.58 ng/g wet wt. in shrimp, and 1.06 – 36.31 and 5.38 – 69.59 ng/g wet wt. in bivalves from Lake Timsah and Bitter Lakes, respectively. High accumulation of Hg was recorded...

Ano: 2006 URL: http://hdl.handle.net/1834/1451 Toxicity of cadmium and copper and their effect on some biochemical parameters of marine fish mugil sheheli OceanDocs Abou El-Naga, E.H.; El-Moselhy, K.M.; Hamed, M.A.. The present work aimed to estimate the toxicity of cadmium and copper to fingerlings of marine fish Mugil seheli, as well as the effect of different concentratios of Cd and Cu on some biochemical parameters (Aspartate and alanine transaminase enzymes, glucose, glycogen, lipid and protein) in the fish organs. 96-h LC50s of Cd and Cu were 5.36 and 1.64 ppm, respectively. Levels of aspartate and alanine transaminase were reduced within 2 days of exposure to different concentrations of Cd (2.0 and 0.5 ppm) and Cu (0.5 and 0.2 ppm) in both plasma and muscle tissue. Glucose was increased reaching the highest values after 4 days of the treatment with Cd and Cu, while muscle glycogen was increased at first days then dropped after 14 days below control level....

Ano: 2005 URL: http://hdl.handle.net/1834/1296 Distribution of vanadium in bottom sediments from the marine coastal area of the Egyptian seas OceanDocs El-Moselhy, K.M.. The present study aims to measure the concentration of vanadium in 73 sediment samples collected along the coastal area of the Egyptian seas (Mediterranean and Red Seas). The results indicated that the mean value of vanadium in Red Sea sediments (52.61 µg/g) was higher than the mean value of the Mediterranean (40.58 µg/g) and the variation between the two means was insignificant (p = 0.241). This result could be attributed to the high petroleum activities of the Red Sea. Along the Mediterranean coast, the sector in front of Port Said area exhibited the highest mean value of vanadium (103.9 µg/g) than other sectors, which suffers from many sources of pollution. While the highest mean value along the Red Sea coast (73.20 µg/g) was found at the sector of Red...
