Mon Nov 18 03:55:43 UTC 2024: **Delhi’s Air Quality at Pollution Hotspots Shows Little Improvement Over Five Years**
NEW DELHI — A new analysis by Hindustan Times reveals that air quality at Delhi’s pollution “hotspots” has not significantly improved over the past five years, despite overall city-wide improvements. The analysis, which compared PM2.5 levels at 33 monitoring stations between October 1 and November 10 from 2019 to 2024, found that while pollution levels at hotspot stations decreased in 2024 compared to 2019, this improvement lagged behind the city’s average reduction.
Eight of the ten most polluted stations in 2019 showed less improvement than the city average, indicating a lack of substantial progress in these areas. While favorable weather conditions, including higher temperatures and faster winds, may have contributed to a slight reduction in 2024, this improvement is not considered sustainable. PM2.5 levels at these hotspots remain high, similar to 2019 levels, with AQIs consistently in the high range.
Although most hotspot stations showed only marginal improvement or no deterioration, the analysis also highlights inconsistencies. Four stations that were relatively cleaner in 2019 experienced significant PM2.5 increases between 2019 and 2024. Furthermore, none of the 33 stations analyzed showed consistent improvement across all five years, raising concerns about the long-term sustainability of any observed reductions. The findings suggest that government interventions have not effectively addressed pollution at these critical hotspots.
