NEW DELHI: Cap­i­tal’s air got worse on Thurs­day with six mon­i­tor­ing sta­tion in the city in­di­cat­ing an Air Qual­ity In­dex (AQI) above 300, which de­fines it as “very poor”.

This was the fifth day when there was no sig­nif­i­cant change in the air qual­ity. The mon­i­tor­ing sta­tions at Anand Vi­har, DTU, Delhi Univer­sity North Cam­pus, Pun­jabi Bagh, Shadipur and NSIT Dwarka all had an AQI of more than 300 on Wed­nes­day.

Anand Vi­har has been iden­ti­fied as the most pol­luted cen­tre fol­lowed by oth­ers.

The of­fi­cials of Cen­tral Pol­lu­tion Con­trol Board as­serted that this con­di­tion is be­cause of the cli­mate and method­olog­i­cal is­sues.

A de­pres­sion in the south and south east of the coun­try, wind speed has de­creased sub­stan­tially in and around Delhi, iden­ti­fied as one the ma­jor me­te­o­ro­log­i­cal cause of this sit­u­a­tion.

Typ­i­cally in win­ter, the wind speed is down mak­ing air qual­ity fouler.

Sci­en­tists of the CPCB as­serted that the air qual­ity is also det­o­nat­ing due to the crop burn­ing in the neighbouring states such as Pun­jab and Haryana.

A se­nior sci­en­tist said that 70 per cent of Delhi pol­lu­tion is caused by crop burn­ing.

He added that the air af­ter the burn­ing of crops in the neigh­bour­hood states en­ters the Cap­i­tal and as this time the cli­mate changes which makes the air heavy so the pol­luted air can­not go out.

An AQI score between 200-300 is clas­si­fied as “poor” as per CPCB stan­dards, and it may cause “breath­ing dis­com­fort to peo­ple on pro­longed exposure, and dis­com­fort to peo­ple with heart dis­ease.”
