NEW DELHI: Delhi-NCR’s pollution during October-November is largely of local origin, with stubble burning in Punjab and Haryana contributing 14 per cent to the overall PM2.5 levels in 2022, a study has suggested.
Researchers, led by those at Japan’s Research Institute for Humanity and Nature under the ‘Aakash Project’, said that changes in the national capital’s air quality could be related more with the stepping up or down of the ‘GRAP’ anti-pollution measures.
The study, published in the journal ‘npj Climate and Atmospheric Science’, analysed fine particulate matter (PM2.5) data, recorded during the September-November months of 2022 and 2023. For the study, 30 sensors were installed across Punjab, Haryana and Delhi-NCR.
