A new study by green group Transport & Environment (T&E) suggests that thousands of cases of high blood pressure, diabetes and dementia across Europe could be linked to the tiny particles emitted by planes. 52 million people - more than 10% of Europe’s total population - live within a 20km radius from the 32 busiest airports in Europe and are particularly exposed to ultrafine particles from aviation, new research by CE Delft and commissioned by T&E finds [1],[2]. In Paris, one of the cities included in the study, 8 million people are affected by its two main airports Charles de Gaulle and Orly. The exposure to ultrafine particles can be linked to the development of serious and long-term health conditions, including respiratory problems, cardiovascular effects and pregnancy issues. (....)
