Abstract

The lower Nile River is a vital drinking and irrigation water source in Egypt. Human activities adjacent to rivers deteriorate the quality of such water resources. The water quality profiles of 23 sites along the Nile were calculated in accordance with the model (Canadian Council of Ministers of the Environment–Water Quality Index [CCME-WQI]). The WQI results indicated that 65%, 100%, and 96% of the Nile River water samples were suitable for drinking, irrigation and aquatic life uses, respectively. These results indicated slight effects on the Nile water quality profile due to different activities, including agricultural runoff and potential industrial and municipal effluents. The metal quality and pollution indices were calculated to assess the contamination with metals (Fe, Mn, Ni, Co, Cr, Cu, Zn, Pb, and Cd). The metal index results for agriculture purposes indicated that the water quality in all collected samples was in the excellent category and had no adverse effect. Moreover, the study showed that the water quality profile of Nile River water had different metal pollution components, notably Pb for drinking and Pb, Co, Cu, and Cd for aquatic life usage, respectively.

埃及尼罗河干流水质剖面及金属污染指数

尼罗河下游是埃及重要的饮用和灌溉水源。河流附近的人类活动使这些水资源的质量恶化。根据模型(加拿大环境部长理事会水质指数[CCME-WQI])计算了尼罗河沿岸23个地点的水质剖面。WQI结果表明，65%、100%和96%的尼罗河水样分别适合饮用、灌溉和水生生物利用。这些结果表明，由于不同的活动，包括农业径流和潜在的工业和城市污水，对尼罗河水质的影响很小。计算金属质量和污染指数，以评估金属(Fe, Mn, Ni, Co, Cr, Cu, Zn, Pb和Cd)的污染情况。农用金属指标结果表明，所有采集样品水质均为优良，无不良影响。此外，研究表明，尼罗河水的水质剖面具有不同的金属污染成分，主要是饮用水中的Pb和水生生物利用中的Pb、Co、Cu和Cd。
