The aim of this study was to assess the level of heavy metals (Cd, Cr, Cu, Fe, Mn, Zn and Pb) in water and sediments of Hindon River in industrialized city Ghaziabad, India. A total of 6 stations, covering the upstream and downstream sites of Hindon, were selected for this study. Metal concentration (mgkg(-1)) ranged: Cd, 1.15-3.47; Cu, 9.42-195.1; Cr, 42.9-250.4; Fe, 221.2-237.9; Mn, 61.0-201.7; Zn, 3.98-85.0; and Pb, 5.07-59.1 in river sediments. The enrichment factor (%) for sediment ranged from 0.05 to 99.8% at point and non-point polluted stations of Hindon. The geoaccumulation index (I(geo)) suggested "unpolluted to moderate pollution" of Mn, Pb and Zn (I(geo)<1), "moderate pollution" of Cu, Cr, Fe (I(geo)<2), and "very strong pollution" of Cd (I(geo)>5) in River Hindon at Ghaziabad city. The industrial and urban discharges in river catchment areas were the major sources of heavy metals in river.
本研究旨在评估印度工业化城市加济阿巴德 Hindon 河水中及河底沉积物中的重金属（Cd、Cr、Cu、Fe、Mn、Zn 和 Pb）水平。共选取了 Hindon 的上游和下游 6 个站点进行研究。金属浓度（mgkg(-1)）范围为：Cd，1.15-3.47；Cu，9.42-195.1；Cr，42.9-250.4；Fe，221.2-237.9；Mn，61.0-201.7；Zn，3.98-85.0；Pb，5.07-59.1。Hindon 点源和非点源污染站点沉积物的富集因子（%）范围为 0.05-99.8%。地质累积指数（I(geo)）表明，Mn、Pb 和 Zn 在 Hindon 河（I(geo)<1）处于“无污染到中度污染”，Cu、Cr、Fe 处于“中度污染”（I(geo)<2），而 Cd 则处于“很强污染”（I(geo)>5）。河流集水区的工业和城市排放是河流重金属的主要来源。
