Profile of Some Trace Elements in the Water - Surficial Sediment of Wadi El-Natrun Depresion Lakes, Egypt
نویسنده
چکیده
Profiles of some trace elements (Fe Mn, Zn, Cu, pb and Cd) were detected in saline water and surficial sediment of Wadi El-Natrun depression lakes. The trace elements concentrations largely indicate the influence of weathering of terrigenous sources on land. The order of the studied trace elements in brine lakes of Wadi El-Natrun from high to low concentrations are Mn > Pb > Fe > Zn > Cu > Cd and Pb > Fe > Cu > Zn > Mn > Cd in ground water well, in addition to in the sediment Fe > Pb > Mn > Zn > Cu > Cd respectively. Also, the present results revealed that Zn, Cd and Pb in saline water of Wadi El-Natrun Lakes are within guidelines except for Cu. In sediment Cd and Pb are higher than guidelines except for Zn.

Search for an adapted forage species for feed production under existing marginal lands and harsh conditions is needed to overcome sever feed shortage in Egypt. Sesbania, Sesbania aegyptiaca (Sesbania sesban, L) has shown potential for forage production and being included in grazing systems, especially on marginal lands and salt–affected soils. An experiment was conducted in the summer of 2004 a...
