Gurgaon: City air quality index (AQI) is 241 on Monday, remaining in the ‘poor’ category for the fourth day in a row due to low wind speed and local factors such as burning of garbage and dust from the construction site.
According to the state pollution control board Haryana (HSPCB), Gurgaon air quality is expected to achieve ‘very poor’ after Diwali, which will be celebrated in 4.
November last year, Aqi City was in the ‘severe’ range two days before Diwali, and continued to remain in The same category until the day after the festival.
According to data from the Central Pollution Control Agency, Gurgaon has the worst AQI post in the last five years in 2020, when reporting AQI 460 a day after Diwali.
In 2016, the day after Diwali (October 31) Aqi was in 298, while at 397 on the appropriate day in 2017 (October 30).
In 2018, Aqi was recorded at 389 on the day after Diwali (November 8), while it was 368 in 2019 (October 28).
On Monday, three of the four city air monitoring stations – Sadan Vikas, Teri Gram and Sector 51 – continue to record the ‘poor’ AQI, while it was not recorded at the GwalPhari station because it was not enough data.
“All departments work on the surface of the ground to ensure that air quality does not deteriorate further,” said the Regional HSPCB (Gurgaon) of Kuldeep Singh Officer.
Meanwhile, HSPCB plans to install the sound level meter in three locations in the city.
The meter responds to changes in sound waves and will monitor pre-diwali noise levels, diwali and post-diwali every hour.
City recorded noise levels only before and after diwali every year to analyze voice pollution.
HSPCB officials acknowledge that noise mapping, although important for the city, has never been done.
“We have a project to install permanent noise monitors in the city soon,” Singh said.
Meanwhile, Delhi’s air quality, which has floated in the ‘poor’ category for the past six days, is likely to change ‘very poor’ around Diwali.
Experts say air quality will likely be starting to deteriorate on Diwali’s day due to burning stumps and winter inversion and, if firecrackers are prohibited from being burned, it may be very affected.
Data from CPCB, which has measured AQI since 2015, shows 2016 has the most polluted diwali with a reading of 431 and 445 the following day.
Delhi 2020 Diwali is the worst since 2016.
Aqi, who was severe at 414 on Diwali, increased to 435 the following day.
The Safar Founder Project Director, Gufran Beig, said, “The wind direction is likely to change from the east to northwest on November 4 on November 4, making it profitable for transportation pollutants issued by stumps of burning to Delhi …” Diwali pollution exploded when exploding.
Crackers, cool winds and cooler nights combined with propeller propellers, he added.
