重金属（铜，铬，铁，铅，锌，汞，镍，镉）和常量营养元素（锰）的浓度进行了测定，工业废水，水，底质和湿地植物从水库，Govind Ballabh（G. B.）潘特萨加尔，在Singrauli工业区，印度。热电厂、煤矿、氯碱废水排入G.B.的排放点。Pant萨加尔被选为采样点，并与一个参考点进行比较。用颗粒物诱导X射线发射法测定了过滤水、筛分沉积物样品（0.4-63 μm）和湿地植物中重金属的含量。所采集的植物为水芹（Aponogetonnatans）、L. Engl. & Krause，Cyperus rotundus，L.，黑藻Hydrilla verticillata（L.f.）Royle，Ipomoea aquatica，Forssk.，四叶马西勒（Marsilea quadrifolia），L.，眼子菜Potamogeton pectinatus L.，凤眼莲Eichhornia crassipes，（Mart.）索尔姆斯莫诺格，青萍属，多根紫萍（L.）施莱德Linnaea，Azolla pinnata，R.Br.，苦草（Vallisneria spiralis），L.，和两栖蓼L.工业废水、湖水和沉积物中重金属含量总体上呈显著正相关（p< 0.01）。植物体内重金属含量与湖泊环境中重金属含量呈显著正相关，进一步显示了上述湿地植物在污染监测方面的潜力。
Concentrations of heavy metals (Cu, Cr, Fe, Pb, Zn, Hg, Ni, and Cd) and macronutrients (Mn) were measured in industrial effluents, water, bottom sediments, and wetland plants from a reservoir, Govind Ballabh (G.B.) Pant Sagar, in Singrauli Industrial region, India. The discharge point of a thermal power plant, a coal mine, and chlor-alkali effluent into the G.B. Pant Sagar were selected as sampling sites with one reference site in order to compare the findings. The concentrations of heavy metals in filtered water, sieved sediment samples (0.4–63 μm), and wetland plants were determined with particle-induced X-ray emission. The collected plants wereAponogeton natans, L. Engl. & Krause,Cyperus rotundus, L.,Hydrilla verticillata, (L.f.) Royle,Ipomoea aquatica, Forssk.,Marsilea quadrifolia, L.,Potamogeton pectinatus, L.,Eichhornia crassipes, (Mart.) Solms Monogr.,Lemna minor, L.,Spirodela polyrhiza(L.) Schleid. Linnaea,Azolla pinnata, R.Br.,Vallisneria spiralis, L., andPolygonum amphibium, L. In general, metal concentration showed a significant positive correlation between industrial effluent, lake water, and lake sediment (p< 0.01). Likewise, significant positive correlation was recorded with metals concentration in plants and lake ambient, which further indicated the potential of aforesaid set of wetland macrophytes for pollution monitoring.
