The geographical location of Bihar cities on the Indo-Gangetic plain makes them vulnerable to air pollution. Ekta Shekhar, founding director of The Climate Agenda, while talking to TOI’s Faryal Rumi, said that while policies exist on paper, their implementation remains weak.

The city recorded a ‘satisfactory' air day for the second day in a row with an Air Quality Index (AQI) of 99 on Sunday.
