Delhi's Deteriorating Air Quality and the AQI

Delhi's air quality deteriorates in October, with high levels of air pollution. The Air Quality Index (AQI) measures the level of air pollution, where higher numbers indicate greater health concerns. Factors contributing to pollution include stubble burning by farmers, festive season fireworks, and poor climatic conditions. To address this, Delhi implemented the Graded Response Action Plan (GRAP), which included measures like odd-even car restrictions, banning diesel generators, and increasing public transport frequency. However, a non-profit analysis found that GRAP focused only on certain particulate matters and did not track other pollutants. Implementation flaws and delayed decisions also hindered its effectiveness.
