Will an app a day keep air pollution away?

Growing concerns over the air quality in metros such as Delhi and Mumbai have led to a surge in mobile apps that keep users updated on the latest pollution levels and health warnings.

In the past one year alone, at least five apps for iOS and Android platforms have been developed by a Pune-based research institute, a Paris-based start-up, a not-for-profit organisation, a personal assistant app and an air purifier firm for metros such as Delhi, Mumbai, Bangalore and Chennai.

Air pollution ‘falls’ in Delhi, claims Safar

The level of suspended particulate matters, PM 2.5 and PM 10, have seen a “steady fall” in Delhi’s air despite a drastic fall in temperature over the last four days, which has the potential to elevate the quantity of such pollutants.

A System of Air Quality and Weather Forecasting and Research (Safar) study termed it as the “first good indicator” of the season and said a “sudden fall in influx of emissions” may explain the fall.
