Current Progress in Hexavalent Chromium by Bibliographic Analysis

Hexavalent chromium contamination poses significant environmental and health challenges, particularly in developing regions where industrial and mining activities pollute water sources. Rainfall and surface runoff transport this toxic compound into groundwater and waterways, leading to severe health risks such as cancer in communities relying on untreated well water. This study employs bibliographic analysis to explore recent advancements in hexavalent chromium remediation technologies. Key approaches include physical methods like activated carbon adsorption, chemical methods such as redox reactions using zero-valent iron, and biological methods leveraging microorganisms like Shewanella oneidensis. Beyond technological solutions, governance frameworks addressing cross-border contamination and national pollution management are critical for sustainable remediation efforts. The study also highlights the future potential of integrating big data and machine learning to optimize remediation strategies. Predictive models trained on extensive datasets can revolutionize contamination management, providing scalable, efficient solutions for mitigating the global risks of hexavalent chromium pollution.
