Air in Ggn sees slight improvement
Gurugram: Residents of Gurugram on Sunday breathed slightly cleaner air than what they had been breathing since Diwali night on November 7.
Favorable conditions ensured that by the afternoon, residents were breathing air that had low concentration of PM2.5 and PM10 pollutants.
Even as a thick layer of smog had enveloped the city in the morning, by 9.00 am, the situation began to improve with PM2.5 levels hovering in 290-350 microgram per cubic metre range. Besides the harmful PM2.5, level of PM10 was registered in 400-450 µg/m³.
The past few days has witnessed high concentration of poisonous gases, such as nitrogen dioxide and sulfur dioxide, emitted mostly by motor vehicles. To save cost, a large number of transport vehicles – especially three-wheelers – use low quality diesel fuel, which causes further damage to the air quality.
