Leveraging plant-based remediation technologies against chromite mining toxicity

Area of Science:

• Environmental Science
• Toxicology
• Bioremediation

Background:

• Chromite mining releases hazardous hexavalent chromium (Cr(VI)) into water, air, and soil.
• Cr(VI) poses significant health risks to humans (respiratory, gastrointestinal, skin) and animals.
• Cr(VI) toxicity impairs plant physiology, affecting germination, nutrient uptake, and growth.

Purpose of the Study:

• To review the environmental and health impacts of hexavalent chromium from mining.
• To highlight sustainable remediation strategies for Cr(VI) contamination.
• To emphasize the role of plants and plant-derived materials in environmental rehabilitation.

Main Methods:

• Review of existing literature on Cr(VI) contamination and remediation.
• Analysis of phytoremediation and nanotechnology approaches.
• Evaluation of biochar as a sustainable remediation agent.

Main Results:

• Hexavalent chromium contamination from mining severely impacts ecosystems and living organisms.
• Phytoremediation and nanotechnology offer innovative solutions for heavy metal removal.
• Biochar, derived from plant waste, is an effective and sustainable material for Cr(VI) remediation.

Conclusions:

• Integrating nature-based solutions like biochar and phytoremediation is crucial for rehabilitating chromite mining regions.
• Sustainable remediation strategies are essential for mitigating the harmful effects of chromium mining.
• Protecting human health and ecosystems requires a holistic approach to managing Cr(VI) contamination.
