NEW DELHI: Air pollution levels in Delhi and Mumbai have begun to reach harmful levels. As temperatures rise, Mumbai’s air quality keeps deteriorating.
On 22ND October, the Air Quality Index (AQI) in Delhi was reported at 302, classifying the air quality as “very poor.” Meanwhile, in Mumbai, the AQI was reported at 132, indicating “moderate” air quality. This increase in AQI in Mumbai is attributed to the sudden change in weather conditions.
Concurrently, the onset of the winter season and a significant increase in vehicle usage in Delhi have worsened the AQI in the city.
The Air Quality Index (AQI) is a scale that ranges from 0 to 500, with higher values signifying more polluted air and a greater adverse impact on health. The Environmental Protection Agency (EPA) calculates the AQI based on five crucial air pollutants: ground-level ozone, particle pollution (particulate matter or PM2.5/PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide.
An AQI reading between 0-50 is considered “good,” 51-100 is “satisfactory,” 101-200 is “moderate,” 201-300 is “poor,” 301-400 is “very poor,” and above 400 falls into the “severe plus” category.”
