“…In Egypt, the degradation of water quality is a major issue, particularly; industrial discharges produce high levels of pollutants that can subsequently contaminate the soil, sediments and surface water systems (Förstner and Salomons, 1991;Dekov, 1997;Evangelou, 1998). As such there has been a great deal of research into finding cost effective methods for the removal of contaminants from wastewater (AbdelGhani et al, 2008;Al-Anber et al, 2008).…”

ABSTRACT:Phytoremediation is increasingly receiving attention as a cost effective technique that uses plants to remediate contaminants from wastewater, soil and sediments. In this study, the ability of Typha domingensis to uptake heavy metals as well as its potential application for phytoremediation was assessed. Pollutant elements concentrations were measured in samples of wastewater, sediments and Typha domingensis collected from industrial wastewater ponds, El-Sadat city, Egypt. This study specifically focused on the capacity of Typha domingensis to absorb and accumulate aluminum, iron, zinc and lead. Results indicated thatTypha domingensis was capable of accumulating the heavy metal ions preferentially from wastewater than from sediments. The accumulation of metals in plant organs attained the highest values in roots, rhizomes and old leaves. Rhizofiltration was found to be the best mechanism to explain Typha domingensis phytoremediation capability.

“…Several previous studies have shown the Manzala region to be the most polluted region in Egypt (Siegel et al 1994(Siegel et al , 1995Stanley et al 1996;Stanley and Warne 1998;El Raey et al 1999;Dekov et al 2001;Dewidar and Khedr 2001;Reinhardt et al 2001;Shamrukh et al 2001). The Manzala Lagoon located within the region is the largest brackish body of water (1071 km 2 ) on the Mediterranean coast of Egypt.…”

“…The Nile delta Core and Sample Database for the Mediterranean Basin Program (MEDIBA) study, which ran from 1985 to 1994 and was sponsored by the Smithsonian Institution, assessed the effect of the Aswan High Dam on the soil and water on northern Egypt. The MEDIBA study, in conjunction with other soil investigations, showed that the construction of the Aswan High Dam in Egypt has led to dramatic changes in the Nile RiverÕs chemistry (Siegel et al 1994(Siegel et al , 1995Stanley 1996;Stanley and Warne 1998;El Raey et al 1999;Dekov et al 2001;Dewidar and Khedr 2001;Reinhardt et al 2001) a massive increase in the use of chemical fertilizers by Egyptian farmers (Shamrukh et al 2001) and a related increase in the heavy metal and pesticide content of the soil (El-sokkary 1992; Siegel et al 1994;AbdelHaleem et al 2001). A comparison of mean heavy metal concentrations in soil sample sediments from 1968 (baseline) and 1993 (more recently) taken during the MEDIBA study showed a consistent increase in heavy metal concentration and exceptionally high levels of heavy metals in soil sediment cores in the Manzala lagoon and neighboring regions in Dakahleia Province.…”

Abstract. The northeast Nile Delta, EgyptÕs most polluted region, appears to have a high incidence of pancreatic cancer. We sought to determine whether there is any geographic clustering of pancreatic cancers there and, if so, whether such clustering might be associated with environmental pollution. Using data from the medical records of the Gastrointestinal Surgical Center of Mansoura University in the Dakahleia Province of Egypt and detailed geographical maps of the northeast Nile Delta region, we plotted the residences of all 373 patients who had pancreatic cancer diagnosed between 1995 and 2000. The study region has 15 administrative districts, whose centroid coordinates, population, and number of pancreatic cancer patients were determined for this study. Monte Carlo simulation identified statistically significant clustering of pancreatic cancer in five subdivisions located near the Nile River and Delta plains. This clustering was independent of population size and formed two larger clusters. When data were analyzed by sex, clustering of pancreatic cancer was observed in the same five subdivisions for men but only two subdivisions showed clustering for women. Together, our data suggest that there is clustering of pancreatic cancer cases in the northeast Nile delta region and that this clustering may be related to water pollution. Our data also warrant future studies of the association between water pollution and pancreatic cancer in the region.

Background: In Egypt, newly diagnosed cases of cholangiocarcinoma are increasing annually. Several reports from Nile Delta show high levels of heavy metals and organocholorine pesticides in the soil and water. We assess serum levels of Heavy metals [Zinc (Zn), lead (Pb), Cobalt (Co), Cadmium (Cd), Chromium (Cr) and Iron (Fe)] as markers of exposure in cholagiocarcinoma patients and healthy controls from the Nile Delta in Egypt and its correlation with tumor differentiation and tumor marker CA 19-9. Methods: We included 45 cholangiocarcinoma patients and 20 healthy controls. All patients and controls were permanent residents of North Delta region and were recruited before receiving chemotherapy or radiotherapy, with no restrictions based on age, sex, or tumor stage. Results: The serum levels of Zn, Pb, Co, Cd and Fe were significantly higher in cholangiocarcinoma patients than controls (P = 0.001). A significant higher serum level of Pb was found in patients with well differentiated to moderately differentiated to undifferentiated tumors (P < 0.05). Cd has a positive correlation with CA19-9 and negative correlation with patients' survival (P<0.5, P<0.01respectively). Conclusions: Cholangiocarcinoma in the Nile Delta region is significantly associated with high serum levels of heavy metals especially Cadmium and lead.
