Ground-level ozone is a harmful air pollutant that forms when sunlight reacts with pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx). These pollutants often come from sources such as vehicles, industrial facilities, and chemical solvents. Unlike the beneficial ozone layer high in the atmosphere, ground-level ozone can cause respiratory problems and other health issues, especially for children, the elderly, and those with pre-existing health conditions. This type of ozone is most prevalent during warm, sunny days, making it a significant concern in urban areas. Efforts to reduce ground-level ozone include regulating emissions from cars, factories, and power plants, as well as promoting cleaner energy sources. Monitoring air quality is essential to protect public health and the environment.
