Arsenic (As) contamination poses significant environmental and public health challenges due to its widespread occurrence and toxicity. Various sources and the extent of As contamination in soils exist that emphasize the urgent need for effective remediation strategies. Traditional and innovative technologies for As removal are explored, focusing on clay modification techniques, microbial remediation, and advanced oxidation reduction processes. The adsorptive ability of As is increased by clay modification, providing an affordable and long-lasting solution. Through procedures that include volatilization, methylation, bioaccumulation, and biosorption, some bacterial and fungal strains that are capable of transformation and detoxification are used in microbial remediation. Promising results have been observed in the reduction of As levels in polluted soils by merging biotechnological technologies with traditional procedures. The study also emphasizes recent developments in the mechanisms by which plants and microbes absorb and convert As, providing information on the development of more effective and environmentally benign remediation techniques. Understanding the interplay between these processes is crucial for optimizing remediation efforts and mitigating the undesirable influence of As contamination on ecosystem and human well-being.
