Field fires and automobile emissions caused North India’s pollution ratings, especially in the national capital region, to fluctuate between ‘severe’ and ‘very poor.’
According to the Indian Agricultural Research Institute (IARI), Punjab has had the greatest number of farm fires this year.
One of the main sources of PM 2.5 pollutants is farm fires. The PM 2.5 particle concentration that can enter the circulation and infiltrate the heart and lungs and is associated with chronic respiratory disorders is measured by the Air Quality Index, or AQI.
