What is Barnet and Harrow Cleaner Air?

Barnet and Harrow Cleaner Air is the overall group of Mayors Air Quality Fund Projects (MAQF) that are run in both Barnet and Harrow. The key aim of the project is to improve air quality throughout both boroughs through a package of measures. 
Poor air quality has the abillity to directly affect your health and many problems are hidden. 
Air quality has been an issue in London since the industrial revolution and the first attemps to clean the air was the Clean Air Act (1957) in response to the 'Great Smog' of 1952.
At the time, it was estimated that 4,000 people had died prematurely, but recent estimates suggest that the figure would have been nearer 12,000. In addition to those that died, 100,000 people were made ill beacuse of the mix of particles and gasses that transport and industry can create.
But becuase of legislation such as the Clean Air Act, these days many people incorrectly assume that air quality is not harming their health, just because they cannot see it. 
However, pollutants such as nitrogen dioxide (NO2), particulate matter (PM) and ozone (O3) are mostly invisible. 
The Mayor's Air Quality Fund (MAQF) aims to address local pollution issues throughout London, with each borough bidding for and delivering projects. Barnet is delivering the North Finchley Cleaner Air Project and Barnet and Harrow are jointly delivering the Air Quality Champion Project.
