Wanted! An army of citizen scientists to tackle air pollution

A Europe-wide project asks iPhone users to help monitor levels of pollution in major cities

Turn off Tinder and exit Instagram - scientists want you to turn your iPhones to research. Launching on Tuesday, the iSpex-EU project aims to recruit people from major cities across Europe, including Manchester and London, to take part in an initiative to monitor levels of air pollution.

Run during the International Year of Light, a worldwide celebration of light and light-based technologies this year, the project aims to raise awareness of air pollution and contribute to scientific research by encouraging people to use their mobile phones to record levels of airborne particles and droplets known as atmospheric aerosols.
