Delhi, which saw a spell of heavy rain a few days back and an improved AQI, is once again facing air quality problems. After the much awaited spell of rain in Delhi, temperatures and air quality have dipped substantially. Delhi’s AQI touched the ‘moderate’ level last week, and it is once again back to the ‘poor’ quality. According to experts, the AQI is expected to rise over the next few days.
This Monday, the AQI of Delhi was seen to be at the 267 mark by the Central Pollution Control Board (CPCB), putting it in the ‘poor’ category. The main pollutants in the atmosphere were noted to be PM2.5 pollutant (123) and PM10 pollutant (206). As per experts, both the pollutants are extremely harmful for one’s health and can cause severe lung issues.
Apart from Delhi, other areas which recorded AQI in the same category were Noida, Greater Noida and Ghaziabad. Surprisingly enough, Gurugram was not part of the ‘poor’ category, but we feel that it is only a matter of time before the AQI dips in these areas as well.
The only reason the AQI hasn’t yet gone down to ‘very poor’ is because of the light winds across the city and surrounding areas. Additionally, temperatures in the city and nearby areas also plunged to lower than average. In the coming days, Delhi could see thick fog and lower temperatures.
The Delhi government had taken several steps to reduce the AQI but most of them have been in vain. They even put up a representational pair of lungs that would suck in the air and give a visual idea of how the AQI tampers the lungs. The lungs turned black in just a few days but did nothing to change habits of residents.
To give you an idea of how AQI works, AQI between 100 and 200 comes under ‘moderate’ category, 201 and 300 is considered ‘poor’, 301 and 400 "very poor", while an AQI between 401 and 500 is ‘severe’.
