Pune: The city recorded the best air quality in this day after 2019 on Thursday, the Safar-measuring air forecasting model from the Indian Institute of Tropical Meteorology (IITM) shows.
Material particles (PM) 2.5 concentration this time is the lowest after that year and the second lowest since 2015.
Despite the activity of firecrackers in the city, weather conditions and fewer vehicle traffic have a major role to be played in reducing overall emissions on Thursday, BS Murthy, Project director, Iitm-Safar, told toi.
Average PM 2.5 levels until Thursday night (9:00) is 59 micrograms per cubic meter (G / M3), second lowest concentration until 2019 on Diwali at 37.7 g / m3.
The maximum allowed for this pollutant is 60 g / m3, so that concentration on Thursday is almost at this level limit.
Tracking the level of pollution in your cityconcentration from pollutants above this is considered harmful to human health.
PM2.5 can cause serious health problems since smaller pollutant particles (less than 2.5 micrometers) move deeper into the lungs and influence breathing.
Murthy told Tii, “Traffic emissions seem to reduce dramatically on Thursday.
Many free roads from traffic – Thursday became a long holiday and earlier weekends.
The level of pollution is usually higher on the day after diwali because pollutants tend to accumulate at the clock early morning.
so clearer images of city pollution levels will appear on Friday.
“He said that cloudy conditions in the city on Thursday because the low-pressure area of ​​the Southeast Arab Sea and Lakshadweep side by side ensured that the minimum temperature in Pune was at Pune higher side.
Thursday recording a minimum temperature of 19.2 degrees C, almost 3.4 degrees C above normal.
“With a higher minimum temperature and relatively windy conditions, pollutants can be spread rather than hanging in the air for a longer time.
Cold temperatures in winter cause layers of atmospheric mixing layers to reduce or fall.
This coupled with a calm wind seen during the season.
This causes pollutants to be stuck close to the surface of the earth, inhibiting their dissolution and cause the level of pollution to increase.
This does not occur on Thursday, “said Murthy further.
Some regions receive rain on Thursday that will wash pollutants.
