Photochemical smog is an atmospheric condition caused by chemical reactions between sunlight, nitrogen oxides, and volatile organic compounds (VOCs). It results in hazy, brownish-colored air containing high levels of ozone near ground level.
Picture yourself walking into a room filled with smoke from burning candles. The combination of light from candles and chemicals in the smoke creates a hazy environment. Similarly, photochemical smog forms when sunlight reacts with pollutants in urban areas.
Ozone depletion: The reduction in ozone concentration in Earth's stratosphere due to human-made substances like chlorofluorocarbons (CFCs).
Volatile organic compounds (VOCs): Organic chemicals that easily evaporate at room temperature and contribute to photochemical smog formation.
Nitrogen oxides (NOx): Gases produced by combustion processes such as vehicle emissions or industrial activities that contribute to the formation of photochemical smog.
