India's Air Quality Worsens: Delhi AQI at 427, NCR Among Worst Hit Areas

Air quality across large parts of India, especially the National Capital Region, remains in the very poor to severe category. Delhi recorded an AQI of 427, while Greater Noida, Ghaziabad, and Noida also showed hazardous levels. Health experts warn of severe respiratory and heart issues. Pollution sources include vehicles, industry, and stubble burning. Government initiatives like NCAP and GRAP are in place, with authorities advising citizens to limit outdoor activities and take precautions.

Air quality in significant parts of India, particularly the National Capital Region (NCR), continues to be in the 'very poor' to 'severe' categories. On December 15, Delhi's AQI reached 427, indicating hazardous conditions. Other severely affected cities include Greater Noida (447), Ghaziabad (444), and Noida (437). This severe pollution has led to a sharp drop in visibility and a haze-obscured skyline. Health experts caution that prolonged exposure can worsen respiratory illnesses, heart conditions, and asthma, especially among children and the elderly. A recent survey revealed that 82% of Delhi-NCR residents know someone suffering from pollution-related health issues.The Air Quality Index (AQI) measures air pollution levels and health risks, calculated from concentrations of key pollutants like PM2.5, PM10, nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone. Major causes of this pollution include vehicle emissions, industrial activities, construction dust, burning of fossil fuels, stubble burning, and waste burning. In response, India has implemented initiatives such as the National Clean Air Programme (NCAP) for 131 cities and the Graded Response Action Plan (GRAP) specifically for the Delhi-NCR region. Other measures include promoting BS-VI fuel standards, electric vehicles, and crop residue management. Authorities have advised residents in affected areas to limit outdoor activities, wear masks, and seek medical advice for any breathing discomfort.
