Ahmedabad Air Quality Surpasses Vadodara, Gujarat Assembly Data Shows
In a significant environmental revelation, data presented before the Gujarat assembly indicates that Ahmedabad's air quality is notably better than Vadodara's on key pollution metrics. This information emerged in response to a question raised by Vadgam MLA Jignesh Mevani, with the government sharing comparative figures that highlight Vadodara's higher particulate pollution levels.
Comparative Pollution Levels: PM2.5 and PM10 Data
The data reveals stark differences in air quality between the two cities. For PM2.5, a fine particulate matter linked to respiratory issues, Vadodara reported a level of 95.81 µg/m³, while Ahmedabad recorded a lower 61.54 µg/m³. Similarly, for PM10, a coarser particulate, Ahmedabad's January reading stood at 141.11 µg/m³, compared to Vadodara's higher 190.36 µg/m³, underscoring poorer air quality in Vadodara.
Detailed Monitoring and Seasonal Trends in Ahmedabad
Further analysis of Ahmedabad's air quality shows seasonal variations. In January, the city's PM2.5 level was 46.54 µg/m³, with the highest reading during the four-month period from October to January reaching 64.39 µg/m³ in November. For PM10, Ahmedabad recorded 99.43 µg/m³ in October, peaking at 150.87 µg/m³ over the same period. These figures, while concerning, remain lower than Vadodara's averages, indicating relatively better air management in Ahmedabad.
Monitoring Infrastructure Disparities
A key factor in the data reliability is the disparity in monitoring networks. Ahmedabad benefits from a comprehensive system with seven stations at locations including Chandkheda, Gyaspur, Isro-SAC Bopal, Isro-SAC Satellite, Raikhad, Rakhial, and SVPI Airport, supplemented by two Gujarat Pollution Control Board stations at Vatva GIDC and Maninagar. In contrast, Vadodara's data is sourced from only one monitoring station at Nandesari, which may affect the accuracy and representativeness of its pollution readings.
This data highlights ongoing air quality challenges in Gujarat's urban centers, with Vadodara facing more severe particulate pollution. The findings underscore the need for enhanced monitoring and pollution control measures across the state to safeguard public health and environmental sustainability.
