The air you breathe can harm your health
AIR pollution has been recognised as a major contributor to ill health for centuries.
While some of the acute effects of smogs, wood and coal burning have been obvious even prior to modern medicine, it is only recently we have started to realise the far greater and more insidious consequences of chronic exposure.
Worldwide, more than 800,000 deaths are now attributed to outdoor air pollution, with annual mortality in the US and the UK 100,000 and 30,000, respectively.
When the consequences of morbidity, lost productivity and lost years of life are considered, the global cost runs into trillions of dollars.
It is a largely silent but truly massive economic and public health issue.
Large epidemiological studies, supported by toxicological and clinical data, have confirmed a wide range of diseases are related to air quality.
There is strong evidence for a causal relationship between air pollutants
