Answer:
Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. ... When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.
