The dirty haze that forms when air pollution combines with moisture in the air is called "smog." This phenomenon typically occurs in urban areas with high levels of pollutants, particularly sulfur dioxide and nitrogen oxides, which react with water vapor to create a thick, fog-like condition. Smog can have detrimental effects on health and visibility.
