Ggn's air quality better, but beyond safety level
GURUGRAM: Three days after Diwali, air quality in Gurugram has improved slightly, but levels of unhealthy particulate matter below 2.5 microns, i.e. PM2.5, are still hovering between 150 and 180, three times above the safety level of 60.
High concentration of other poisonous substances, like nitrogen oxide, sulphur dioxide and carbon monoxide were also notice. Though traffic on the city roads was less on account of the long Diwali weekend, presence of harmful particulate matters was high.
There are also fears that air quality will deteriorate from Monday, when heavy vehicular traffic will choke Gurugram's roads. Despite a large campaign organised to celebrate Diwali without crackers, a large number of citizens came out and burnt firecrackers. This resulted in air quality in the Millennium City deteriorating to hazardous levels.
The levels of PM2.5, the prolonged exposure of which can cause irreversible lung ailments, were recorded at 420 microgram per cubic metre.
PM2.5 levels gradually came down to 330 after 9.00 am on the morning after Diwali.
