Spilled liquid mercury: case studies, proposition of safety procedures with assessment of commercial cleanup kit and recommendations.

Mercury, in its elemental form (Hg(0)), has intrigued humanity since antiquity, but its toxicological risks have become more apparent in recent times. Metallic mercury exposure primarily occurs through vapor inhalation, affecting the central nervous system and causing symptoms such as tremors, cognitive impairments, and renal damage. Mercury contamination, often linked to artisanal gold mining and industrial spills, poses environmental and health challenges worldwide. Addressing these hazards requires effective mercury spill management practices. Guidelines from the EPA and WHO emphasize the need for immediate containment, avoiding vacuum cleaners or brooms, and using specialized spill kits. Best practices include isolating contaminated areas, increasing ventilation, and safely disposing of mercury. Large-scale spills may require professional decontamination, including chemical stabilization with sulphur. The manuscript underscores the importance of adopting comprehensive spill management strategies to mitigate both immediate and long-term health risks associated with mercury exposure, offering practical recommendations for handling spills in various environments.
