Designed to help decrease the harmful substances that create smog in the air.
The city implemented antismog regulations to improve air quality.
Antismog is formed from "anti-" (meaning against) and "smog" (a blend of smoke and fog, originating from the early 20th century). The word refers to measures or actions taken against smog or air pollution.
Think of 'anti-' meaning against, and 'smog' referring to the polluted air. This helps you remember that antismog means actions taken against air pollution.
