Pollution caused by crackers on Diwali
by Amar K. Hi, there
Last year fireworks pushed pollution in Delhi to a dangerous level on Diwali, the worst in three years, as it turned the air highly toxic due to a deadly cocktail of harmful respirable dust pollutants and gases, engulfing the city with a cover of thick smog triggering health alarms. Various monitoring agencies including Delhi Pollution Control Committee (DPCC), Central Pollution Control Board, Pune – based SAFAR and Centre for Science and Environment were unanimous about the severity of the air quality in the city.
As per DPCC’s real time monitoring mechanism, the ultra pollutant PM 2 . 5 breached the safe standard by over 14 times at Anand Vihar, Delhi’s most polluted area, at installment payments on your 30a m. Many other areas including densely populated R K Puram had nearly similar readings when pollution peaked past mid night.
Noise pollution, which was monitored in five locations in the city, was marginally higher than last year as it ranged between 66. 1 decibel(A) and 75. Coupled with moisture and almost stagnant wind movement, shrouded the city in a thick cover of smog. Commuters in several areas found it difficult to find their way as the visibility level plunged to almost zero in many areas.
The court hopes the ban, which will also cover the festival falling on October 19, will help improve air quality in the Capital. People who have already purchased fireworks will be able to use them. Diwali festivities leave the city and adjacent areas engulfed by a toxic cloud of smoke and hazardous levels of fine particulate matter (PM 2.5) that pose the greatest threat to lungs.
SAFAR, an agency of Earth Sciences Ministry, said air quality was not only severe but stepped to its worst in three years during Diwali mainly due to low wind motion and falling boundary layer, that traps pollutants close to the surface. The most critically contaminated period was between 11a meters on October 30 and 10a meters upon Monday. Which can aggravate asthma, On Diwali night, dPCC said. 5, Particles that measure less than 2 . The prescribed regular for it is 60.
