“…Through these mechanisms, it is possible to verify the interactions between plants and soil, that is, an indicator of plant species adaptation. Phytoremediation can be modeled by the accumulation of contaminants in the plant by metabolization and monitoring the soil and water of contaminated areas (Hasanuzzaman et al 2017;Mandal et al 2014). The selection of mechanisms for phytoremediation planning depends on the objectives, which are associated with the advantages and disadvantages of each model applied, for the complete understanding of the level of results (Janani et al 2019;Kumar Yadav et al 2018;Muthusaravanan et al 2018).…”

The contamination of soils and groundwater has attracted worldwide attention, since many contaminants are poorly biodegradable and can accumulate in living organisms, causing implications for plants, animals, and human health. The high cost of conventional remediation processes stimulates research for the development of innovative and more sustainable techniques. Likewise, phytoremediation is a cheap technology that uses plants to absorb, transform, and detoxify contaminants through in situ (phytoextraction, phytotransformation, and phytovolatilization) and ex situ mechanisms (phytostabilization and phytostimulation). Recently, phytoremediation has been adopted as a more profitable technique than physicochemical processes. Otherwise, the existence of variables, such as interactions between climate, soil, and plants, requires analysis methods for its implementation, which ensure the reduction of time and cost and improve its efficiency. Research on the application of different phytoremediation techniques is still in progress, and therefore, this study evaluated the main advantages of phytoremediation through a literature overview, comparing the most adequate remediation models in terms of economic, social, and environmental aspects. Highlighted Conclusions1. Phytoremediation consists of the use of plants and their associated microbes for environmental cleanup and recovery of contaminate soil. 2. Phytoremediation promotes social-economics benefits comparing to the conventional techniques, and ensures sustainability in environmental rehabilitation.

Soil Contamination - Threats and Sustainable Solutions

Increased threat of metals simultaneous to the biota well-being and the environs is continually causing a major apprehension worldwide. The phytoremediation technique is highly advantageous involving the natural processes of plants viz., translocation, evapotranspiration, and bioaccumulation, thus degrading contaminants slowly. In particular, nanophytoremediation is a rapid green alternative as it reduces the ancillary impacts of the environment such as green gas emissions, waste generation, and natural resource consumption to the present scenario as there is a great potential of nanoparticles from plants which can be synthesized. Nanophytoremediation is a current methodology for remediation of pollutants, contaminants by using synthesized nanoparticles from plants. In this, the use of different strategies enhances the selective uptake capabilities of plants. The metal elements in excess are affecting the physiological processes in plants; thus, it is necessary to apply nanophytoremediation technology through transgenic plants. In this review paper, we focused on plant species, which can be used as metal tolerant, hyperaccumulators. Due to the insurmountable pressure of a sustainable cleaner environment, bioremediation can be concurrent with nanoparticles for efficient and effective sustainable measures.

“…Most of the phytoremediation processes are targeted on inorganic pollutants through different attempts which is termed as phytoextraction (the utilization of metal accumulating species to transport and accumulate metals from the soil to roots and above ground biomass), rhizofiltration (the utilization of plant roots to absorb, precipitate and concentrate toxic contaminants from polluted effluents, phytovolatilization (some metal pollutants such as As, Hg and Se occur in gaseous forms in the environment; scientists have recently discovered genetically-modified plants that are capable of absorbing metals in their elemental forms from the soil, thus converting them biologically to gaseous species within the plants and release them into the atmosphere) and phytostabilization (the utilization of plants in lowering down the mobility of metals) (Mandal, 2014).…”

The historical lakes of India are getting over burdened with the loads of pollution due to the rapid growth of small scale industries, nutrient enrichment and other anthropogenic activities. The high concentrations of metals in the water bodies, their entry into ecological food chain and the resulting health effects are of great concern to the researchers in the areas of ecology. Due to the problems associated with the conventional methods of pollutant removal, phytoremediation method is gaining more attention. The plants to be used in this technique, it must have high capacity of metal absorption, its accumulation and reduction in the time of decontamination in an ecosystem. It is an environment friendly and cost beneficial technique for the removal of toxicants from the environment. This article present over view on status of heavy metal pollution in lake and remediation through plants in Indian context may helpful to researcher not only in India but around the world also. This base line data can help governmental and non-governmental organization for the management of water pollution.
