Industrial smog is a type of air pollution that primarily results from the burning of fossil fuels, such as coal and oil, in factories and power plants. It consists of a mixture of smoke, sulfur dioxide, and other pollutants, which can create a thick, gray haze in the atmosphere. This type of smog is most common in urban areas with heavy industrial activity. The formation of industrial smog is often exacerbated by weather conditions, such as temperature inversions, which trap pollutants close to the ground. Health effects can include respiratory issues and irritation of the eyes. Efforts to reduce industrial smog have led to stricter regulations on emissions from factories and power plants.
