Study: Urban grime releases NOx when exposed to sunlight

Green Car Congress

When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. In a subsequent laboratory comparison, they found that nitrate disappeared from grime 10,000 times faster than from a water-based solution when both were exposed to artificial sunlight.
