Water quality assessment of the River Nile system: an overview.

摘要: Objectives The main objective of the present article is to assess and evaluate characteristics Nile water system, identify major sources pollution its environmental health consequences. also aimed highlight importance management via re-use recycle treated effluents for industrial purpose cultivation desert land. Method An intensive effort was made by authors collect, compile available data about River Nile. Physico-chemical analyses were conducted check validity collected data. For determination micro-pollutants, Gas Chromatography (GC) High Performance Liquid (HPLC) used. Heavy metals determined investigate level in river system. Results revealed that receives a large quantity industrial, agriculture domestic wastewater. It worth mentioning still able recover virtually all locations, with very little exception. This due high dilution ratio. confirmed presence concentrations chromium manganese sediment samples. residues organo-chlorine insecticides detected locations. However, levels such are usually below limit set WHO use as drinking water. most polluted lakes Lake Maryut Manzala.Groundwater closely related adjacent (polluted) surface waters. nutrients, E. coli, sulfur, heavy metals, etc. have been observed shallow groundwater, largely surpassing standards use. Conclusion A regular continuous monitoring scheme shall be developed law enforced prohibit discharge wastewater (agricultural, or industrial)
