What are the effects of prolonged exposure to automotive exhaust on PVC sculptures?
Prolonged exposure to automotive exhaust can significantly impact PVC sculptures, leading to visible and structural damage over time. The harmful chemicals in exhaust fumes, such as nitrogen oxides and sulfur dioxide, react with the PVC material, causing discoloration, surface erosion, and weakening of the sculpture's integrity. UV radiation from sunlight can accelerate this degradation, making outdoor PVC sculptures particularly vulnerable.
To mitigate these effects, artists and collectors should consider protective coatings, regular cleaning, and displaying sculptures in sheltered areas. Understanding these risks helps preserve PVC artworks and maintain their aesthetic and structural quality in polluted environments.
