How do aluminum outdoor sculptures handle exposure to mercury in contaminated sites?
Aluminum outdoor sculptures are known for their durability and resistance to environmental factors, including exposure to mercury in contaminated sites. Mercury, a toxic heavy metal, can accelerate corrosion in many metals, but aluminum forms a protective oxide layer that helps mitigate damage. This passive layer prevents mercury from penetrating deeply, reducing structural harm. However, prolonged exposure in highly contaminated areas may still cause surface degradation over time. Artists and conservators often apply protective coatings to enhance resistance. Regular maintenance and inspections are recommended to ensure longevity. Aluminum remains a preferred material for outdoor art due to its balance of aesthetic appeal and environmental resilience.
