In a modest improvement, Delhi experienced a slight amelioration in air quality overnight, registering an Air Quality Index (AQI) of 339 at 9 am. This follows a shift from the "very pooꦛr" category, though concerns persist regarding the capital's atmospheric conditions. Monitoring agencies reported the AQI at 405 on Friday at 4 pm, highlighting the fluctuating nature of air quality.
Despite rigorous measures implemented by the city government, such as a ban on construction activities andꦬ restrictions on diesel trucks, Delhi's air quality has faced challenges due to various factors. The aftermath of Diwali celebrations, intensified stubble burning in neighboring state🍌s, and unfavorable meteorological conditions, including calm winds and low temperatures, have hindered the dispersion of pollutants.
Vehicular emissions emerged as a significant contributor, constituting approximately 45 percent of the capital's air pollution on Friday, according to findings from a joint project by the Delhi government and the Indian Institute of Technology (IIT), Kanp🌃ur. Secondary inorganic aerosols, resulting from the interaction of gases and particulate pollutants, accounted for 19 to 36 percent of recent air pollution.
The India Meteorological Department (IMD) is optimistic about a potential reduction in air pollution levels with an anticipated improvement 🔜in wind speed from November 21 onwards. Despite these efforts, Delhi ranked as the second-most polluted city globally on Saturday, as reported by air-quality monitoring specialist IQAir.
Stringent measures, including those outlined in the Graded Response Action Plan (GRAP), will continue under the oversight of a n♓ewly established six-member special task force (STF). The STF, led by Delhi's special secretary (environment), comprises officials from key departments such as transport, traffic, revenue, Municipal Corporation of Delhi (MCD), and Public Works Department (PWD). The Commission for Air Quality Management (CAQM) reaffirmed that these measures will persist until further orders.
