Every year, despite intense lobbying from concerned citizens the air pollution levels rise to dangerous levels after Diwali. The no-cracker campaign fails to draw support from the masses.
In Delhi, air pollution levels reached 40 times over the safe limits this year. According to news reports, “Many areas in the city witnessed zero visibility, including railway stations, highways, and airports.” Last week, the Delhi High Court reportedly called Delhi and NCR areas a gas chamber.
News media reported that the particulate matter — PM 2.5 and PM 10 — pollutants reached levels at least 15 times above the safe limits in Delhi. “The Delhi Pollution Control Committee reported that air quality in places like RK Puram was 42 times worse than what can be called safe. Seven out of the 10 most polluted places in the country were reported in the capital after Diwali which is an alarming metric, a report in the Indian Express said.
Toxic pollutants can cause grave health issues and are even considered carcinogenic. Though this year with the ban on Chinese-made crackers and a 20 percent dip in sales by local manufacturers, the air quality post-Diwali did not show any improvement.
In Mumbai too, the Air Quality Index (AQI) went up to 320 on Monday, falling under the ‘very poor’ AQI category.
With the media focusing only on Delhi and Mumbai to report the worsening air pollution after Diwali, the pollution levels in other cities – which may very well be higher – often get unreported.

Ahmedabad-based Oizom has developed a mobile app that helps users analyse and compare the ‘real time’ air-quality of about 100 cities around the world. Their aim is to help users take necessary precautions and plan their day-to-day activities without exposing themselves to air pollutants unnecessarily.
Users can also compare the air quality levels of their city with other global cities to see how they differ. Oizom’s database also contains information about the different pollutants measured in parts per million (ppm) present in the air. Currently, Oizom obtains raw data from publicly available sources (such as Indiaopendata), but in the near future it aims to deploy its own IoT devices to provide more accurate data for both outdoor and indoor air pollution monitoring.
