Question
The main component of photochemical smog is
Solution 1
The main component of photochemical smog is ozone. This is formed when sunlight reacts with nitrogen oxides and volatile organic compounds in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. Volatile organic compounds are released from gasoline, paints, and many cleaning solvents. When sunlight hits these chemicals, they form airborne particles and ground-level ozone—or smog.
