The context of measurements of concentrations of atmospheric pollutants traditionally carried out by the authorities in charge of ambient air monitoring is changing. In particular, we observe the evolution of the general public’s sensitivity to the environment, the crystallization of individuals on their health in relation to the environment and food, the publicity around 400 000 deaths in Europe, but also on pollution peaks, traffic restriction measures, an upsurge in the number of asthmatics and even allergies, and a lot of contradictory information blurring the messages …
These findings are in line with the way in which current generations, inseparable from their smartphone, operate, and with the increasing use of connected objects and biomedical tests. There is therefore a proliferation of applications displaying the value of the pollutant (s) at time “T” and at point “P”, resulting from measurements made public by ASQAA or from modeling.
At the same time the manufacture and use of inexpensive, individual and miniaturized sensors is being developed, supported by ever more powerful algorithms and capable of managing and exploiting the enormous databases generated by these measurements. This has allowed the emergence of several projects – often with a “citizen” ambition in France or abroad, sometimes including the manufacture itself of the sensor. We can quote: “What is your air? The PMClab, “Ambassad’Air”, Mobicit’Air, etc.
In this very innovative and dynamic context, in France and abroad, the APPA wishes to organize an international symposium, in partnership with Lille University (PC2A laboratory) and EFCA (European Federation of Clean Air and Environmental Protection Associations), in order to establish a state of the art and to provoke reflections on different axes:
- Technology and metrology: what measurements? Which pollutants? What reliability? What standardization? What about using these sensors in indoor air?
- The health aspect: what individual impact? what contribution for epidemiological studies, under what conditions?
- The societal and big data component: ownership and management of the data generated?
- The economic and strategic aspect: real cost of sensors? Economic model ? Monitoring the implementation of emission reduction actions?
- What do we learn from the first feedback? Actual use by citizens? Changes in behavior?
