Delhi-NCR pollution: How GRAP Stage 1 curbs can protect your heart and lungs
On October 21, 2026, the Commission for Air Quality Management (CAQM) activated Stage 1 of the Graded Response Action Plan (GRAP) across the Delhi-NCR region after the Air Quality Index reached 244, classifying the air as poor. This activation followed the conclusion of Dussehra celebrations and marks the first instance of poor air quality recorded for the current season. The implemented measures include mechanized road sweeping, water sprinkling, strict dust control at construction sites, and bans on open waste burning to curb emissions of particulate matter like PM2.5 and PM10. Medical experts emphasize that while these early interventions cannot instantly render polluted air safe, they are critical for preventing further deterioration and reducing cumulative exposure. Physicians warn that fine particles pose significant risks to both respiratory and cardiovascular systems, potentially triggering inflammation and increasing strain on the heart even in individuals who do not experience immediate symptoms.
Mumbai has emerged as the most polluted city in India, ranking fifth globally on the iQAir air quality index as of Thursday. The city recorded an Air Quality Index (AQI) of 152, which falls under the "unhealthy" category on the US-based platform's scale. Ground-level ozone (O3) was identified as the primary pollutant, according to iQAir. This follows a period of abnormally high temperatures and humidity, exacerbated by a rain-deficient monsoon season. The elevated temperatures have led to three of the hottest days in at least a decade this month, with maximum temperatures consistently 4-5 degrees Celsius above normal on multiple days. Atmospheric scientist Gufran Beig attributed these conditions to an El Niño pattern affecting wind speeds significantly. He explained that reduced wind circulation allows pollutants to accumulate in the lower atmosphere, increasing pollution levels. The discrepancy in air quality assessments between iQAir and India's Central Pollution Control Board (CPCB) stems from differences in their respective AQI scales. While iQAir reports an AQI of 152, the CPCB's reading stands at 98, categorized as "satisfactory." These varying standards mean the figures are not directly comparable, with each organization highlighting different primary pollutants, ground-level ozone for iQAir and particulate matter such as PM2.5 and PM10 for the CPCB. In contrast, Delhi's air quality has shown signs of deterioration, with the AQI rising to 179 on Tuesday, placing it in the "moderate" category. According to forecasts from the Indian Institute of Tropical Meteorology (IITM), the situation is expected to worsen, moving into the "poor" category by Wednesday and remaining there for the subsequent six days. The main pollutant in Delhi has shifted from ozone and PM10 on Monday to PM2.5 on Tuesday. Transport emissions continue to be the leading source of pollution in Delhi, contributing approximately 23.02% of the city's emissions. Other contributors include residential sources at around 6%, and industries, construction, road dust, waste burning, and the energy sector collectively accounting for roughly 15%. Stubble burning is anticipated to play a more significant role, with its contribution projected to increase from 4% to 12% by Wednesday. Satellite data from the Indian Agricultural Research Institute indicated that between September 15 and October 19, 1,171 instances of crop residue burning were recorded across six states and Delhi. On Monday alone, 98 such events were noted, primarily in Punjab, Haryana, Madhya Pradesh, and Uttar Pradesh. No incidents were detected in Haryana or Delhi on Monday, according to the latest data. The decline in air quality coincides with falling temperatures and altered wind patterns, which influence how pollutants disperse. The India Meteorological Department reported that the minimum temperature in Safdarjung base station reached 17.7 degrees Celsius, with the maximum temperature at 31.8 degrees Celsius, both below normal. A slight increase in temperatures is forecasted within the next 48 hours. Surface winds in Delhi are expected to slow down to around 10 kmph from the northeast during the evening and night, following stronger afternoon winds from the northwest. The ventilation index, a measure of the atmosphere's capacity to disperse pollutants, is projected to be 13,700 square metres per second on Wednesday, increasing slightly to 21,600 square metres per second by Friday. However, indices below 6,000 square metres per second, coupled with wind speeds less than 10 kmph, are considered detrimental to pollutant dispersion.
