City Statistics: Air quality

The long-term pollution index shows the average air pollution of towns and cities. Chronic pollution by air pollutants such as particulate matter, nitrogen dioxide and ozone has a direct impact on human health and the environment. This may result in respiratory diseases such as bronchitis as well as an increased risk of cancer.
