Dear student
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a contraction (portmanteau) of the words smoke and fog to refer to smoky fog due to its opacity, and odor.  Summer smog is primarily associated with the photochemical formation of ozone.
thanks and regards
