These ‘HoLu kits’ are being distributed in pilots to residents who live in regions where the air quality is poor, such as around the Tata steel factory in the IJmond area. We teach citizens to measure the surrounding air quality and to interpret the data.

Such data collection generally followed apaper-based approach, with volunteers either systematically recordingobservations or individually sending evidence such as photographs orspecimens to professional scientists, along with key metadata such asobservation time and location
