The air becomes heavier in the winter as compared to the summer, causing poisonous particles in the atmosphere to move downwards and making the atmosphere polluted. As a result, a layer of polluted particles, including large amounts of carbon and smoke, covers an area.
The smoke produced by burning crop remnants, factories, and burning coal, garbage, oil or tyres enters the atmosphere, and the impact of this appears at the onset of winter and remains till the season's end, experts added.
The situation has raised concerns about the long-term impact of air pollution on the city's inhabitants.
