Water quality index (WQI) of Narora channel and health of endemic fish Bagarius bagarius and plant Eichhornia crassipes, district Bulandshahar, Uttar Pradesh, India were studied. Among the physicochemical properties of water, pH, D.O, Cr, Fe, Ni, and Cd were above the recommended standards. These factors lead to high WQI (4124.83), indicating poor quality and not suitable for drinking and domestic usage. In fish tissues, the highest metal load was reported in the liver (58.29) and the lowest in the kidney (33.73). Heavy metals also cause a lowering of condition indices. As expected, decreased serum protein (- 63.41%) and liver glycogen (- 79.10%) were recorded in the exposed fish. However, blood glucose (47.22%) and serum glycogen (74.69%) showed elevation. In the plant, roots (21.50) contained the highest, and leaves (16.87) had the lowest heavy metal load. Bioaccumulation factor (BAF) > 1, indicates hyperaccumulation of all metals. E. crassipes roots showed the highest translocation factor (TF) > 1 for Ni (1.57) and Zn (1.30). The high mobility factor (MF) reflected the suitability of E. crassipes for phytoextraction of Mn, Cd, Zn, Fe, Ni, and Cu. Moreover, Bagarius sp. consumption could not pose any non-cancer risk. Although, lower cancer risk can be expected from Ni and Cr.
印度北方邦布兰德沙哈尔区纳罗拉河的水质指数 (WQI) 以及特有鱼类印度鱯和凤眼蓝的健康状况得到了研究。在水质的理化性质中，pH 值、D.O、Cr、Fe、Ni 和 Cd 均高于推荐标准。这些因素导致 WQI 较高（4124.83），表明水质较差，不适合饮用和家庭使用。在鱼类组织中，肝脏中的金属负荷最高（58.29），肾脏中的金属负荷最低（33.73）。重金属还导致了鱼类健康状况指数的下降。正如预期的那样，暴露于重金属的鱼类血清蛋白减少了（-63.41%），肝脏糖原减少了（-79.10%）。然而，血糖（47.22%）和血清糖原（74.69%）水平升高。在植物中，根部（21.50）的重金属负荷最高，而叶片（16.87）的重金属负荷最低。生物积累系数（BAF）>1，表明所有金属均发生了超积累。凤眼蓝根部的 Ni（1.57）和 Zn（1.30）的转移系数（TF）>1，表明其具有较高的转移能力。高流动性系数（MF）反映了凤眼蓝适合用于 Mn、Cd、Zn、Fe、Ni 和 Cu 的植物提取。此外，印度鱯的食用不会带来任何非癌症风险。虽然 Ni 和 Cr 的摄入可能会带来较低的癌症风险。
