What term describes the mixture of smoke and fog that reduces visibility and air quality in polluted urban areas?

Explanation

Smog is a term combining the words smoke and fog, describing a type of air pollution that forms when smoke, vehicle exhaust, and other pollutants mix with atmospheric moisture, particularly under certain weather conditions that trap pollutants close to the ground. It can cause reduced visibility and pose respiratory health risks, especially for vulnerable groups like children, the elderly, and people with asthma. Major cities around the world periodically experience smog episodes, particularly during colder months when temperature inversions trap pollutants near the surface.
