Anyone who lives, works or plays sport in Brussels breathes litres of air every minute. That air is free, but it is incredibly precious and important for our health. But how good is the air quality in Brussels? CurieuzenAir calls on everyone's cooperation to find out.

In order to get an idea of the health of the air in Brussels, 3,000 Brussels residents started a large-scale measurement last Saturday. With test tubes attached to their windows, they measured the amount of nitrogen dioxide in the air outside for four weeks.

The CurieuzenAir study is a collaboration of BRUZZ, De Standaard and Le Soir with the University of Antwerp, city movement BRAL and the Université Libre de Bruxelles. It is part of the Brussels Clean Air partnership, an initiative to tackle air pollution. It is supported by Bloomberg Philanthropies and Bruxelles Environnement. It is the first large-scale citizen survey on Brussels air quality.

Besides the King, the Prime Minister, the European Commission and numerous families, schools and companies, the RBINS is also taking part in this research! Over the next four weeks, you will be able to see an information board to the right of the entrance to the Museum of Natural Sciences, with test tubes hanging from the windows of the first floor. CurieuzenAir was launched on 25 September 2021, the results will be announced in February 2022.
