Photochemical Smog
Photochemical smog is a type of air pollution that is formed when sunlight reacts with nitrogen oxides and volatile organic compounds (VOCs) in the atmosphere. This reaction produces a mixture of harmful pollutants, including ground-level ozone, aldehydes, and peroxyacyl nitrates (PANs). Photochemical smog is typically found in urban areas with high levels of traffic and industrial activity, and can have serious health effects on humans and the environment. Exposure to photochemical smog can cause respiratory problems, eye irritation, and damage to crops and other vegetation.
