Monitoring Wadi El Raiyan Lakes of the Egyptian Desert for Inorganic Pollutants by Ion-Selective Electrodes, Ion Chromatography, and Inductively Coupled Plasma Sepectroscopy

摘要

Wadi El Raiyan is a great depression located southwest of Cairo in the western desert of Egypt, one of the most arid regions of the world. In 1937, Wadi El Raiyan was connected with the agricultural wastewater drainage system of the El Faiyum province to provide a reservoir for the wastewater that exceeded the capacity of Lake Qarum north of the province. Pollutants from agriculatural waste including pesticides and fertillizers as well as other effluents of indutrial activities and runoffs certainly will pass into the biotic elements of the ecosystem.
