The biggest source of smog today varies depending on the location, but a significant contributor worldwide is the burning of fossil fuels, particularly in vehicles and industrial processes. The combustion of fossil fuels releases pollutants, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), which are key components in the formation of smog.
To determine the biggest source of smog in a specific area, you can refer to local air pollution control agencies or environmental department reports. These organizations monitor and analyze air pollution sources, including emissions from factories, power plants, vehicles, and other industrial processes. Additionally, scientific studies and research articles provide valuable insights into the major sources of smog in different regions.
By staying informed about local air quality measures and supporting initiatives to reduce emissions, we can collectively work towards minimizing the sources of smog and improving air quality.
