Interactive map of air pollution

In March 2014 the World Health Organization (WHO) published a report which stated that only in 2012, air pollution led to the death of 7 million people. Over the last decade the number of people breathing polluted air has increased from 606 million to 1.78 billion people, a quarter of the world's population.

Later it was published by WHO database 2014 on air pollution in cities, which contains data on more than 1,600 cities located in 91 countries, 500 more than in the previous database in 2011. Air quality is represented as the average annual concentration of aerosol particles ranging in size from 10 to 2.5 microns (PM10 and PM2.5, respectively). The database covers the period from 2008 to 2013. The greatest amount of data obtained in 2011 and 2012. The database is available on the WHO website.

Interactive map are based on the WHO database in 2014 for cities, as well as on the basis of satellite measurements of aerosol particles in the countries. Map provided an opportunity to compare national data with air pollution in cities, to understand how air pollution is distributed globally.
