Hundreds of Melbourne children will set off on their school commutes wearing specially designed backpacks to monitor air pollution in the city's asthma-prone inner west.
The "Breathe Melbourne" study, enlisting more than 300 students and a dozen teachers from six schools, is an attempt to shed light on pollution in the area and help policy makers better tackle the issue.
Deakin University researchers are homing in on the inner west as a focal point for the project given it has higher levels of air pollution than other areas of the city.
