Despite Delhi's severe "very poor" air quality, experts note the usual spike in pollution from farm fires in Punjab and Haryana has not yet happened.

The deteri­or­a­tion in Delhi’s air qual­ity, which was skirt­ing the “very poor” cat­egory on Sunday, was caused more by external factors than from sources within the cap­ital, accord­ing to the Centre’s Decision Sup­port Sys­tem (DSS).
