Why these areas in Punjab, Haryana are most to blame for your toxic air

Ahead of the crop stubble-burning season, a study by IIT-Delhi has identified which districts in the neighbouring states of Punjab and Haryana contribute the most to Delhi’s air pollution in October and November. The study — based on wind direction, intensity of farm fires and their proximity to the capital — stated that Amritsar, Tarn Taran, Firozpur, Ludhiana, Faridkot, Bathinda, Mansa, Patiala and Sangrur in Punjab and Hisar, Sirsa and Kaithal in Haryana were the biggest contributors.
