Up to 11% of new childhood asthma cases could be prevented each year if European countries complied with the WHO PM2.5 air quality guidelines. Moreover, 33% of new annual cases could be prevented in European countries if they were able to reduce air pollution levels to lowest levels recorded in the literature. Those are the conclusions of a study led by the Barcelona Institute for Global Health (ISGlobal) and published in the European Respiratory Journal.
Asthma is the most common chronic disease in children. Emerging evidence suggests that exposure to air pollution may increase the risk of developing this respiratory disease during childhood. The new study has estimated the burden of childhood asthma in 18 European countries and more than 63.4 million children and has concluded that a large number of cases may be attributable to air pollution exposure. The attributable percentage of new annual cases varies according to each of the three pollutants studied: 33% for PM2.5, 23% for NO2 and 15% for black carbon (BC).
