By:Prof. Nand Lal( Dean, Faculty of Life Sciences & Former Pro-Vice Chancellor C.S.J.M. University Kanpur & Editorial Group Advisor-Science & Tech ICN Group) KANPUR:Phytomining has several unique features like (1) It offers the possibility of exploiting ores or mineralised soils that are uneconomic by conventional mining methods. (2) ‘Bio-ores’ are virtually sulphur-free, and their smelting requires less energy than sulphidic ores. (3) The metal content of a bio-ore is usually much greater than that of a conventional ore and therefore requires less storage space despite the lower density of a bio-ore. (4) Phytomining…

By: Prof. Nand Lal( Dean, Faculty of Life Sciences, Former Pro-Vice Chancellor, C.S.J.M. University,Kanpur & Editorial Group Advisor-Science & Tech-ICN Group) KANPUR:Phytomining is a technique that uses certain plants to mine metals out of sub-economic ore bodies including soil or polluted waters. Phytominers grow a crop of a metal-hyperaccumulating plant species, harvest the biomass and burn it to produce a bio-ore. Use of phytomining has grown over the last decade, particularly in remediating contaminated lands such as mine tailings or old factory sites where metals have leached into the ground. Some of the plant species…

By: Prof. Nand Lal (Dean, Faculty of Life Sciences & Former Pro-VC, C.S.J.M.Kanpur University) & Priti Sachan (PhD Scholar)     The presence of lead in the drinking water can cause damage to the kidney, nervous system, and learning difficulties. KANPUR: Water resources in the world have been profoundly influenced over the last years by human activities, whereby the world is currently facing critical water supply and drinking water quality problems. Increased urbanization and industrialization are to blame for an increased level of trace metals, especially heavy metals in water bodies. In…
