Urban pollution is a major environmental issue in many cities around the world. It is caused by a variety of factors, including NOISE, SMOG, and smaze. NOISE is a form of air pollution that is created by loud sounds from vehicles, construction sites, and other sources. SMOG is a type of air pollution that is created by the burning of fossil fuels and other pollutants. Smaze is a combination of smoke and haze, which is created when pollutants mix with dust particles in the air. All three of these forms of urban pollution can have serious health and environmental impacts.
