We can save tens of thousands of lives with fresh air

New one Transfer 50,000 people a year would live in Europe if the clean air level recommended by the World Health Organization was maintained, according to reports According to the World Health Organization, air pollution kills 7 million people a year worldwide, and the situation is especially dangerous in cities.

WHO experts believe that for PM2.5, the concentration in air should not exceed 10 milligrams per cubic meter. For nitric oxide, the maximum has been set at 40 milligrams per cubic meter.

According to the new study, the pollutants mentioned above cause premature deaths in about a thousand cities in Europe. It is estimated that by limiting PM2.5 and nitrous oxide to safe levels, more than 51,000 Europeans could be protected each year, and if the standard low concentration could be achieved, 125,000 people could be saved annually. Marc Neuenhugsen of the Institute for Global Health in Barcelona thinks the latest results also show that many cities still fail to combat air pollution today.

Researchers combined air pollution and mortality data to create a classification of the most polluted cities. According to the data, Madrid is one of the most dangerous places in terms of nitric oxide, and PM2.5 concentrations cause high mortality in the Po Valley, Hungary, Poland and the Czech Republic. Overall, 7 percent of the urban population surveyed had a higher recommended nitric oxide and 84 percent higher than prescribed levels of PM2.5.
