Seasonal variations in outdoor air quality refer to the fluctuations in pollutant concentrations and overall air quality that occur throughout the year, influenced by factors such as temperature, humidity, and human activities.

This article examines how seasonal changes affect specific pollutants like ozone, particulate matter, and nitrogen dioxide, highlighting the health implications associated with these variations. It also discusses the economic impacts of poor air quality, the role of meteorological conditions, and human activities that contribute to seasonal changes.
