Fitorremediação de solos contaminados por metais pesados

Abstract

In this study conducted between September and October 2023, a bibliographicresearch encompassed articles from 2000 to 2023, including older sources due totheir relevance. The methodology involved the analysis of monographs, dissertations, books, and scientific articles from SciELO, Google Scholar, and CAPES Periodicals databases, focusing on phytoremediation of heavy metals. The study highlights the global urgencyin combating soil contamination by heavy metals, demonstrating that certain plants not only absorb but also reduce the toxicity of these metals, offering hope for extensivelycontaminated areas. Phytoremediation is seen as a sustainable alternative, requiringbroad implementation, public education, effective policies, and collaboration betweenscientists and communities for a healthier and preserved environment for futuregenerations. Considering the urgency in addressing heavy metal contamination, strategies such as phytoextraction, phytostabilization, and phyto-volatilization, alongwith the use of hyperaccumulator plants like those from the Brassica genus, areessential to protect human health and preserve the environment. These techniques, alongwith innovations such as the use of chelating agents and plant regulators, are crucial totackle the challenges of soil contamination by heavy metals. Collaboration amongscientists, policymakers, and local communities is essential to implement thesesolutions effectively and sustainably, providing a safer and healthier future for everyone.
