Projects that recruit the public are getting more ambitious and diverse, but the field faces some growing pains.
As a biogeochemist at the University of Antwerp in Belgium, Meysman wasn’t used to drawing so much attention. But that was before he adopted the citizens of northern Belgium as research partners. With the help of the Flemish environmental protection agency and a regional newspaper, Meysman and a team of non-academics attracted more than 50,000 people to CurieuzeNeuzen, an effort to assess the region’s air quality (the name is a play on Antwerp dialect for ‘nosy’ people).
The project ultimately distributed air-pollution samplers to 20,000 participants, who took readings for a month (see ‘Street science’). More than 99% of the sensors were returned to Meysman’s laboratory for analysis, yielding a bounty of 17,800 data points. They provided Meysman and his colleagues with information about nitrogen dioxide concentrations at ‘nose height’ — a level of the atmosphere that can’t be discerned by satellite and would be prohibitively expensive for scientists to measure on their own. “It has given us a data set which it is not possible to get by other means,” says Meysman, who models air quality.
