The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, andHydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water. The results show that theE. densaandH. verticillataare able to accumulate high amount of arsenic (95.2%) and zinc (93.7%) and resulted in a decrease of arsenic and zinc in the ambient water. On the other hand,C. piauhyensisshows remarkable aluminium accumulation in plant biomass (83.8%) compared to the other tested plants. The ability of these plants to accumulate the studied metals and survive throughout the experiment demonstrates the potential of these plants to remediate metal enriched water especially for mine drainage effluent. Among the three tested aquatic plants,H. verticillatawas found to be the most applicable (84.5%) and suitable plant species to phytoremediate elevated metals and metalloid in mine related waste water.

Calcium is an essential mineral which supports bone health as well as serves as a major therapeutic intervention that can prevent and delay the incidence of osteoporosis.Multicellular aquatic plants like are a rich source of plant based calcium. The Characterization of Plant based calcium and Synthetic calcium sources using sophisticated analytical techniques. Plant based Calcium and Synthetic Calcium sources were subjected to instrumental analysis such as SEM, ICP-OES and XRD, and comparisons were done followed by interpretation.In this study, three different instrument techniques like SEM, ICP-OES and XRD were used for the characterization of plant based calcium and synthetic calcium. The results showed that plant based calcium were smaller crystals as compared to synthetic calcium crystals. Further, in case of XRD results, plant based calcium is shown to possess two 2θ values, whereas in case of synthetic calcium, it showed a single 2θ value. Further, Magnesium and Boron content were higher in case of plant based calcium as compared to synthetic calcium. Both Plant based and Synthetic Calcium can be distinguished using SEM, ICP-OES and XRD techniques. Outcomes of this study enlightens the probable reasons for enhanced bioavailability in case of plant based calcium sources as compared to synthetic sources.
