Smog is a type of air pollution. It is a mixture of different pollutants and particles, and forms under certain weather conditions.
Smog is a problem in most big cities. Melbourne can get photochemical smog in the summer, and winter smog in the colder months.
Photochemical smog is a haze caused by sunlight mixing with chemicals in the warm air. Winter smog is a build-up of fine particles trapped in the cold air.
