How vehicular pollution is not primary cause of poor air quality in Delhi
FirstpostIn March this year, a most authoritative study on the subject pointed out that in winter the real reason for air pollution is something else: biomass burning In its Air Quality Life Index report for 2023, the University of Chicago’s Energy Policy Institute has said that air pollution cuts short the lives of people of Delhi by about 11.9 years. In March this year, a most authoritative study on the subject pointed out that in winter the real reason for air pollution is something else: biomass burning. In the study, published in the prestigious Nature Geoscience journal, the scholars “observe[d> intense and frequent nocturnal particle growth events during haze development in Delhi from measurements of aerosols and gases during January-February at the Indian Institute of Technology in Delhi… We estimate that this process is responsible for 70 per cent of the total particle-number concentration during haze”. It further said, “As uncontrolled biomass burning for residential heating and cooking is rife in the Indo-Gangetic plain, we expect this growth mechanism to be a source of ultrafine particles, affecting the health of 5 per cent of the world’s population and impacting the regional climate.” In other words, the health of almost 40 crore people is adversely affected by biomass burning.
