Mumbai Aqi’s moderate witnesses in Diwali

Mumbai: As with severe pollution predictions at night Diwali on Thursday, Mumbai witnessed a moderate air quality index (AQI) around 150-165 which means breathing discomfort for people with lungs, asthma and heart disease.
Thanks to normal temperatures, moisture and wind speed.
Since the beginning of this week, Aqi City is in a poor category, i.e., between 201 and 300.
Mumbai is predicted to touch AQI above 300, which is considered a very bad quality that causes respiratory disease in terms of prolonged exposure.
However, Safar has estimated that the pollution level will rise in the city and will reach a very bad category between Thursday night and Friday morning.
As appropriate for estimates AQ Safar, the most polluted area is expected to be Navi Mumbai, BKC and Chembur on November 4 and November 5.
The main reason behind AQI is very poor, according to experts, humble and high humidity in an environment that cannot disperse smoke originating from vehicles, burning of garbage, dust and construction industry.
Exceeding and above, firecrackers add fuel to the fire.
However, on Thursday temperatures, wind speed and moisture are close to the normal level.
In AQI, particle concentration of 2.5 material in the air mainly decides air quality because of its presence rises if severe pollution activities occur in the middle of high humidity and low wind speeds.
According to the quality of the air forecasting the air and research (Safar), the concentration of PM 2.5 (a suspended pollutant of 2.5 microns or a smaller size) is 75 micrograms / cubic meters, which is 1.2 times the daily security limit.
In accordance with the national ambient air quality standards, a 60ug / m3 daily security limit for PM 2.5 must be maintained.
PM 2.5 is one of the most prominent pollutants in the city.
The highest level of PM 10 and 2.5 is estimated for early hours of I.E., between 1am and 4 in the night of 4 and November 5, but will begin to increase the next day, he said.
As appropriate, the concentration of PM 2.5 can go to 182ug / m3, which will be almost three times more than a 24-hour security limit.
PM concentration 10 is likely to be 275 UG / m3 on Friday.
While 2020 saw a bad AQI around 270 even though the fire department was lacking, Diwali 2019 was cleaner with better air quality because of low temperatures and gusty winds.
