Cities in Europe with the cleanest air named

Scientists from Spain, Switzerland and the Netherlands have assessed the air quality in European cities. In their study, they covered 47 megacities and 969 smaller settlements from 31 countries, according to The Lancet Planetary Health.

The authors noted that the most hazardous to health are atmospheric particulate matter with a diameter of about 2.5 micrometers (PM 2.5) and nitrogen dioxide emissions. They cause chronic illness and can even lead to premature death.

Scientists analyzed how air pollution affects the mortality of local residents aged 20 and older. It turned out that people are least likely to die from poor ecology in the Nordic countries.

The lowest number of deaths from exposure to PM 2.5 was recorded in Reykjavik (Iceland), Troms (Norway) and Umeå (Sweden). The lowest exposure to nitrogen dioxide was observed in Tromso, Umeå and Oulu (Finland).

Scientists also named the cities with the most unfavorable environmental conditions. Most deaths from PM 2.5 were in Brescia and Bergamo (both Italy) and Karvina (Czech Republic), from nitrogen dioxide – in Madrid, Antwerp and Turin.

The authors emphasized that reducing the level of air pollution will help avoid hundreds of thousands of deaths a year. They called for a revision and lowering of the current standards for the content of harmful particles in the air.

Previously it was reported that polluted air can provoke the development of Alzheimer's disease. But the negative effect is only seen in women.
