Air Pollution

The greatest health problem we face. The WHO reports that air pollution is now the largest, single, environmental health risk

The invisible killer

Air pollution is the daily harm we can’t see. An increasing risk to public health in urban areas, it affects us on our streets, in our homes, at our place of work and even as we travel.  Harmful pollutants, like nitrogen oxides (NOx), particulate matter (PM2.5) and ozone (O3) can build up to levels that are dangerous for the health of everyone.  

Where does air pollution come from?

In cities, there are two main sources. Mobile sources, such as cars, buses, vans, planes, and trains, especially those running diesel engines; and Stationary sources such as power plants, industrial factories and refineries.

What pollutants are created?

Air pollutants in cities are usually made up of Nitrogen Dioxide (NO2) from diesel vehicles, Particulate Matter 2.5 and 10 which are fine airborne particles, Carbon Monoxide from home appliances, and Ozone from ultraviolet radiation and chemical reactions with other airborne pollutants.

What is a pollution “hot spot”?

Pollution hotspots are places with a high density of people, high emissions and long dwell time. Hotspots in cities usually occur at transport hubs, in parks and playgrounds close to roads, outdoor eating/drinking areas and inside ground floor shops along high streets.

The human cost of air pollution

1 in 8 deaths

The World Health Organisation1 reports that air pollution is now the world’s largest single environmental health risk. In 2012 it found that one in eight global deaths were as a result of air pollution exposure.

Reduced life expectancy

Pollutants not only stay behind in your lungs they also enter the bloodstream and are dispersed throughout the body getting into all vital organs. Long-term exposure to NO2 has been directly linked to lung cancer, cardiovascular mortality2, as well as increasing the risk of respiratory problems3.

Environmental impact

Ozone (O3) is the main component of smog and greenhouse gasses. Some hydro-carbons, that contribute to O3, are considered toxic and can have a detrimental effect on asthma and other respiratory diseases.

Babies and children

Long-term exposure to NO2 has been directly linked to decreased lung function in school aged children, low birth weight of newborns4 and increased risk of respiratory problems5.
