Abstract The Bahr Yusuf Canal is the life artery of the Fayoum Province, which provides the province with two thirds of the freshwater quota from the Nile River. The present work was carried out to assess the suitability of water in the Bahr Yusuf Canal for various purposes and to assess the potential health risk associated with metal content. The results showed that the water quality of Bahr Yusuf was classified as poor and very poor for recreational use according to the Oregon WQI. On the other hand, the Aquatic Toxicity Index indicated the suitability of water for all fish species. The Canadian WQI and the Weighted Arithmetic WQI classified the canal water as good (WQI = 92), fair (WQI = 73) & marginal (WQI = 64) and excellent, poor to good & good to excellent for irrigation, drinking and aquatic life, respectively. Despite the significant contamination of water with heavy metals (as indicated by the Heavy Pollution Index, ranging from 104.44 to 206.32, from 16.81 to 38.48 and from 219.07 to 472.24 μg l−1), the Hazard Quotient (HQ) and the Hazard Index (HI) data indicate that water of Bahr Yusuf does not pose a human health risk through ingestion or dermal contact. In general, the study showed that water in the Bahr Yusuf Canal is characterized by different levels of pollution, which requires rapid and critical intervention by responsible authorities to prevent the discharge of different types of waste and further deterioration of the water quality during the lifetime of the channel and its subsequent rehabilitation.

埃及法尤姆 Bahr Yusuf 运河水质指标和健康风险评估的综合方法

摘要 Bahr Yusuf运河是法尤姆省的生命动脉，为该省提供了尼罗河淡水配额的三分之二。目前的工作是为了评估 Bahr Yusuf 运河中的水对各种用途的适用性，并评估与金属含量相关的潜在健康风险。结果表明，根据俄勒冈州 WQI，Bahr Yusuf 的水质被归类为差和非常差，无法用于娱乐用途。另一方面，水生毒性指数表明水对所有鱼类的适宜性。加拿大 WQI 和加权算术 WQI 将运河水分为良好 (WQI = 92)、一般 (WQI = 73) 和边缘 (WQI = 64) 以及优秀、差到好、好到优，适合灌溉、饮用和水生生物， 分别。尽管水被重金属严重污染（如重污染指数所示，范围为 104.44 至 206.32、16.81 至 38.48 和 219.07 至 472.24 μg l−1），但危害商数 (HQ) 和危害指数（ HI) 数据表明 Bahr Yusuf 的水不会通过摄入或皮肤接触对人类健康构成威胁。总体而言，研究表明，优素福河运河中的水具有不同程度的污染特征，这需要主管当局进行快速和关键的干预，以防止排放不同类型的废物，并在生命周期内进一步恶化水质。通道及其后续修复。48 和从 219.07 到 472.24 μg l-1)，危害商数 (HQ) 和危害指数 (HI) 数据表明 Bahr Yusuf 的水不会通过摄入或皮肤接触对人类健康构成风险。总体而言，研究表明，优素福河运河中的水具有不同程度的污染特征，这需要主管当局进行快速和关键的干预，以防止排放不同类型的废物，并在生命周期内进一步恶化水质。通道及其后续修复。48 和从 219.07 到 472.24 μg l−1)，危害商数 (HQ) 和危害指数 (HI) 数据表明 Bahr Yusuf 的水不会通过摄入或皮肤接触对人类健康构成风险。总体而言，研究表明，优素福河运河中的水具有不同程度的污染特征，这需要主管当局进行快速和关键的干预，以防止排放不同类型的废物，并在生命周期内进一步恶化水质。通道及其后续修复。
