The term “smog” was coined more than five decades ago to describe a mixture of smoke and fog in the air. Today smog refers to a noxious mixture of air pollutants, including vapours, gases and particles that can often be seen as a yellowish-brown haze in the air. When inhaled, its impact on human health varies depending on air pollutant levels, type of pollutants, and length of exposure, as well as factors such as age, weight, activity level and health status of those exposed to it.
