Clean-Up of Heavy Metals from Contaminated Soil by Phytoremediation: A Multidisciplinary and Eco-Friendly Approach

Toxics, Journal Year: 2023, Volume and Issue: 11(5), P. 422 - 422

Published: May 2, 2023

Pollution from heavy metals is one of the significant environmental concerns facing world today. Human activities, such as mining, farming, and manufacturing plant operations, can allow them access to environment. Heavy polluting soil harm crops, change food chain, endanger human health. Thus, overarching goal for humans environment should be avoidance contamination by metals. persistently present in absorbed tissues, enter biosphere, accumulate trophic levels chain. The removal contaminated accomplished using various physical, synthetic, natural remediation techniques (both situ ex situ). most controllable (affordable eco-friendly) method among these phytoremediation. metal defilements phytoremediation techniques, including phytoextraction, phytovolatilization, phytostabilization, phytofiltration. bioavailability biomass plants are two main factors affecting how effectively works. focus phytomining on new hyperaccumulators with high efficiency. Subsequently, this study comprehensively examines different frameworks biotechnological available eliminating according guidelines, underscoring difficulties limitations its potential application clean-up other harmful pollutants. Additionally, we share in-depth experience safe removing used phytoremediation—a factor frequently overlooked when choosing remove conditions.

A Green Approach Used for Heavy Metals ‘Phytoremediation’ Via Invasive Plant Species to Mitigate Environmental Pollution: A Review

Plants, Journal Year: 2023, Volume and Issue: 12(4), P. 725 - 725

Published: Feb. 6, 2023

Heavy metals (HMs) normally occur in nature and are rapidly released into ecosystems by anthropogenic activities, leading to a series of threats plant productivity as well human health. Phytoremediation is clean, eco-friendly, cost-effective method for reducing soil toxicity, particularly weedy plants (invasive species (IPS)). This provides favorable tool HM hyperaccumulation using invasive plants. Improving the phytoremediation strategy requires profound knowledge uptake translocation development resistance or tolerance HMs. review describes comprehensive mechanism HMs their subsequent detoxification with IPS via phytoremediation. Additionally, improvement through advanced biotechnological strategies, including genetic engineering, nanoparticles, microorganisms, CRISPR-Cas9, protein basis, discussed. In summary, this appraisal will provide new platform uptake, translocation, process IPS.

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.
