Air quality index crossed 150 across several residential and commercial areas in Ahmedabad in the first week of November, leaving the city's air toxic ahead of Diwali. Residents are already reporting eye irritation, throat infections and persistent coughing.
On Kali Chaudas, readings stood at 157 in Maninagar, 156 in Nikol, Judges Bungalow, Isanpur, Chandkheda and Rakhial, 154 in Naranpura, Ghatlodia, Narol and Shahibaug, 152 in Bapunagar and 151 in Fatehwadi, Gyaspur and Ugbatpur.
Doctors warn of a post-Diwali surge
Doctors warn of a surge in respiratory emergencies after Diwali firecrackers, especially among children, the elderly and those with existing conditions. The warning comes as the festival approaches and cracker use is set to rise sharply.
What is polluting the air
Industrial emissions from Vatva, Odhav, Narol and Pirana are among the sources blamed for the poor air, along with alleged night burning of old tyres, plastic and waste oil. Vehicle exhaust, traffic congestion and construction dust are also blamed.
Frequent fires at the Pirana dumping site add smoke and toxic gases to the air, making the problem worse for neighbourhoods nearby.
Advice for residents
Doctors advise children, the elderly and respiratory patients to limit outdoor exposure, especially early in the morning and late at night, and to wear well-fitted masks. The advice is aimed at the groups most at risk from the toxic air.
The Diwali test ahead
With AQI already above 150 before the festival, the coming days will test the city's air further. Firecrackers, traffic and the usual winter conditions could push readings higher still.
How far the air worsens after Diwali will depend on cracker use, wind and the enforcement of pollution controls, but doctors say the safest course for vulnerable residents is to stay indoors as much as possible and wear a mask outside.
