The European Environment Agency has finalized an agreement with an ESA-led consortium to provide unparalleled information on air pollution, which contributes to the premature deaths of hundreds of thousands of Europeans annually. The service includes data on ozone, nitrogen dioxide and particulate matter (the sum of all particles suspended in air, including dust, smoke, pollen, etc.). Exposure to these pollutants can cause adverse health effects such as decreased lung function, increased respiratory symptoms and allergic responses, according to the World Health Organization.
