Giant Mural Helps To Clean City Air [Pics]
By using a special photocatalytic paint, an artist's wall painting can help reduce smog.
Italian artist Andreco has arguably created one of the first murals that helps fight air pollution. Andreco used a five-story apartment building as his canvas to paint a 59-foot mural that can reduce the amount of nitrogen monoxide in the air. He used a special photocatalytic paint that is able to clean the air of photochemicals such as smog.
