New Delhi, November 16, 2023.
Delhi’s air quality fluctuated between the very poor and severe categories on Thursday as unfavourable meteorological conditions hindered the dispersion of pollutants.
Recent findings from a joint project by the Delhi government and IIT-Kanpur found that vehicular emissions accounted for about 38 percent of the capital’s air pollution on Wednesday. This is projected to rise to 40 percent on Thursday.
Secondary inorganic aerosols — particles such as sulfate and nitrate that are formed in the atmosphere due to the interaction of gases and particulate pollutants from sources like power plants, refineries, and vehicles — is the second major contributor to Delhi’s foul air, accounting for 30 to 35 percent of the air pollution in the city over the last few days.
