Mineral ballast effect: dual potential of enhanced carbon sequestration and pollution reduction in karst lakes

Key Points

• Enhanced carbon sequestration occurs through the coupling of minerals and organic matter, facilitating sedimentation.
• The biological pump effect, driven by high levels of dissolved inorganic carbon, demonstrates significant ecosystem potential.
• Phosphorus sequestration achieves long-term stability, reducing risks associated with water eutrophication in karst environments.
• The findings highlight the need for innovative strategies in ecological carbon management and water quality improvement.
