North In­dia ex­posed to se­vere air pol­lu­tion lev­els morn­ing af­ter Di­wali

The Northlines - - NATION -

Large parts of north In­dia woke up to “se­vere” air qual­ity on Thurs­day, a day af­ter Di­wali fire­crack­ers added to the al­ready de­te­ri­o­rat­ing pol­lu­tion lev­els across the re­gion. Luc­know and Mo­rad­abad in Ut­tar Pradesh and Bi­har’s cap­i­tal Patna recorded se­vere air qual­ity in­dex (AQI) of 421, 401 and 423 re­spec­tively around 9am. Delhi, Ut­tar Pradesh’s Agra and Ghazi­abad and Farid­abad in Haryana also had AQI in “very poor” cat­e­gory with the air qual­ity wors­en­ing very rapidly at in­di­vid­ual sta­tions in the na­tional cap­i­tal af­ter 3am on Thurs­day. Par­tic­u­late mat­ter or PM2.5 (fine, res­pirable pol­lu­tion par­ti­cles) lev­els went up to “se­vere +” cat­e­gory con­sid­ered to be the most dan­ger­ous that can trig­ger health im­pacts even among healthy peo­ple. PM2.5 lev­els peaked to more than 1,000 mi­cro­grams per cu­bic me­tres at some sta­tions in Delhi on Thurs­day morn­ing but the av­er­age lev­els hov­ered around 700 mi­cro­grams per cu­bic me­tres com­pared to a safe stan­dard of 60 mi­cro­grams per cu­bic me­tres. Ur­bane­mis­, a re­search or­gan­i­sa­tion that tracks air qual­ity in all dis­tricts through satel­lite mea­sure­ments, re­leased a district wise map on Thurs­day show­ing the north­ern states in se­vere air qual­ity.

It also re­leased a line graph show­ing the im­pact of burst­ing of fire­crack­ers on air pol­lu­tion spike in Delhi and the Na­tional Cap­i­tal Re­gion (NCR) over Wed­nes­day night and Thurs­day morn­ing.
