After a recent rainfall, Delhi's mercury levels fell, bringing the AQI into a satisfactory range.
Delhi experienced a notable drop in mercury concentration following a rainfall event, according to data reported by Hindustan Times.
The reduction in mercury has contributed to a lower Air Quality Index (AQI), which now falls within the satisfactory category.
Meteorological conditions during the rainfall helped wash out particulate matter and trace gases, improving overall air quality.
Authorities and environmental groups welcome the improvement, though they caution that sustained efforts are needed to maintain cleaner air.
