Title : Green remediation of heavy metal pollution: Advances in sustainable strategies for environmental and public health protection
Abstract:
Heavy metal pollution poses a great threat to the environment and public health since it is persistent, bioaccumulative, and toxic. Conventional remediation approaches of chemical treatment and excavation are prone to forming secondary environmental impairments. Green remediation practices have been reported to be environmentally friendly, cost-effective, and environmentally friendly options for mitigating heavy metal contamination. This review highlights new technologies in green remediation approaches such as phytoremediation, bioremediation, and nanotechnology-based remediation. The application of hyperaccumulator plants, microbial-assisted detoxification, and biochar amendments has been found to significantly decrease metal toxicity while rejuvenating the fertility of soil. The application of green-synthesized nanoparticles further enhances the immobilization of metals and their uptake efficiency without any residual toxic effects. The application of these techniques combined with recent biotechnological tools has improved the efficiency of remediation, hence making them good prospects for large-scale applications. This presentation focuses on the public and environmental health benefits of sustainable remediation methods, citing them as capable of enhancing long-term environmental security. The presentation will also mention some of the challenges such as low metal uptake rates and long treatment durations and propose avenues for future work to enhance green remediation techniques. Adopting these measures will contribute significantly towards reducing exposure to heavy metals and promoting environmental sustainability globally.
