“…They exhibit toxicity in the natural soil that harbors vegetation (Foy et al, 1978;Yizong et al, 2009). The excessive use of phosphatic fertilizers, industrial wastes, and sewage sludge applications release several toxic heavy metals/metalloid such as Cd, Cr, Pb, and As into agricultural soil (Bell et al, 2001;Schwartz et al, 2001;Passariello et al, 2002;Yadav, 2010). Later, these heavy metals enter into the ecosystem and food chain through absorption and accumulation processes in plants and animals, affecting them severely (Yamagata and Shigematsu, 1970;Cervantes et al, 2001;Vernay et al, 2007;Yizong et al, 2009;Kumar et al, 2013).…”

Iron (Fe) is a micronutrient that plays an important role in agriculture worldwide because plants require a small amount of iron for its growth and development. All major functions in a plant's life from chlorophyll biosynthesis to energy transfer are performed by Fe (Brumbarova et al., 2008;Gill and Tuteja, 2011). Iron also acts as a major constituent of many plant proteins and enzymes. The acquisition of Fe in plants occurs through two strategies, i.e., strategy I and strategy II (Marschner and Römheld, 1994). Under various stress conditions, Nramp and the YSL gene families help in translocation of Fe, which further acts as a mineral regulatory element and defends plants against stresses. Iron plays an irreplaceable role in alleviating stress imposed by salinity, drought, and heavy metal stress. This is because it activates plant enzymatic antioxidants like catalase (CAT), peroxidase, and an isoform of superoxide dismutase (SOD) that act as a scavenger of reactive oxygen species (ROS) (Hellin et al., 1995). In addition to this, their deficiency as well as their excess amount can disturb the homeostasis of a plant's cell and result in declining of photosynthetic rate, respiration, and increased accumulation of Na + and Ca − ions which culminate in an excessive formation of ROS. The short-range order hydrated Fe oxides and organic functional groups show affinities for metal ions. Iron plaque biofilm matrices could sequester a large amount of metals at the soil-root interface. Hence, it has attracted the attention of plant physiologists and agricultural scientists who are discovering more exciting and hidden applications of Fe and its potential in the development of bio-factories. This review looks into the recent progress made in putting forward the role of Fe in plant growth, development, and acclimation under major abiotic stresses, i.e., salinity, drought, and heavy metals.

“…Safe disposal of mine tailings is one of the major environmental problems in the world. The use of special dumping facilities (such as dams or ponds) represents a convenient disposal method; however, the formation of stockpiles on the ground surface can cause serious environmental pollution and ecological damage [3] as well as other problems such as tailing dam failures [4][5][6]. Therefore, the utilization of mine tailings for backfilling underground voids is a better way of disposing of these solid wastes.…”

Pore Structure Evolution and Its Effect on Strength Development of Sulfate-Containing Cemented Paste Backfill

Abstract:In this study, the effects of the initial sulfate content on the properties of cemented paste backfill (CPB) made from coarse tailings has been investigated via mercury intrusion porosimetry. The combined effects of the sulfate content and curing time on the total porosity, pore size distribution, and unconfined compressive strength of the produced material were discussed. It was found that the specimens with an initial sulfate content of 5000 and 35,000 ppm exhibited higher unconfined compressive strength, while the resulting fine porous structures characterized by pore radii of 10-400 and 1-10 µm significantly improved the mechanical properties of the CPB. In addition, an increase in the curing time decreased the overall pore volume in the radius range of 1-400 µm but increased the pore volume at pore radii less than 1 µm.
