Scaling solutions to a global challenge
ย Our community lives with an invisible problem that potentially has wide-ranging impacts on both individuals and the economy as a whole: air pollution.
As citizens we have a legal right to clean air โ but to be able to assert this right we must have access to information, as stipulated by the Aarhus Convention. Yet air quality was last measured in Sรณller in 2007.
We believe that the right to access information about air quality is a precondition to the right to clean air: unless people know that there is an air quality problem, understand the risk it poses to their health and are informed about what measures are being taken to improve it, they are powerless to take action.ย
We canโt tackle what we canโt measure.ย
Because air pollution is hard to see, itโs often hard for us to pinpoint sources and trends to develop effective solutions. New sensor technology is changing that dynamic, allowing us to measure and map pollution concentrations street by street across the community and identify patterns and hotspots like never before.ย
Compared to conventional air pollution management, which commonly relies on a few sparsely located (and very expensive) monitors and modeling, hyperlocal monitoring allows for a more holistic picture of air quality at a high spatial resolution (with different concentrations every 100 meters, for example) and frequency (different concentrations every minute or few minutes, rather than on an hourly or daily basis).ย
Remember: different pollutants are present and travel in different ways, making a monitor in one spot often unable to detect a danger even 100 steps away. Research shows that air pollution is not evenly distributed and can in fact be up to eight times worse on one end of a street as another.ย
After an initial campaign deploying hand-held monitors, we are now committed to building a community air monitoring network. The goal of the community air monitoring network is to provide residents with accurate, real-time, local air quality data that may also be useful in scientific analysis. While these sensors are not approved by government regulatory agencies for use in regulatory actions, and their data cannot be used in legal cases, they can provide supplemental data that may be useful to communities, academic researchers, agencies, and others.
All information is available online, in real time, via our website map. In the future, we will also launch an app. Citizens will be able toย sign up for alerts when levels of air pollution are high or when air quality is particularly low at a specific location, such as a school or sports stadium.
Using SDS011 particulate matter sensors, we form part of a wider network of 13,500 sensors worldwide in 73 countries. This is a successful citizen science initiativeย which was initially established by OK Lab Stuttgart, Germany. OK Lab Stuttgart is part of the Code for Germany program of the Open Knowledge Foundation Germany, an organisation that works to enable access to knowledge and encourage democratic participation by developing technologies and tools that strengthen civil society.

Monitoring Goals
Defining the pollutants of interest is a critical step in designing our network and choice of instruments. Air pollutants have different physical properties, as well as different health impacts, which have implications for how best to measure and map them. The pollutants we want to measure will be driven primarily by the emission sources of concern and the risk to human health.
In the case of the Sรณller valley, we have chosen to measure particulate matter, PM 2.5 and PM 10.
Our immediate monitoring goals are:
- Identify air pollution problem and assess severity
- Create awarenessย
- Investigate source
Data Objectives
Our data objectives are focused on:
- Quantifying air pollution levels and characterizing pollution patterns across the valley
- Creating awarenessย
- Quantifying air pollution levels and characterizing pollution and associated health impact patterns across the valley
- Identifying the presence of pollutant(s) in excess of health benchmarks
- Identifying suspected emission sources (hotspots)

Sempre que mir, mai està ni regular a sa zona dels estiradors, iper sant jaume, on els dos semàfors, el que no comprenc és que al diari veu de Sóller, a da portada, hi ha un petit mapa on sempre diu que es respirable, i cuan clikes i obris, veus que no és així com es possible aixo? Gràcies.

Los investigadores dicen que la exposiciรณn a largo plazo incluso a niveles relativamente bajos de PM2,5 aumenta el riesgo de depresiรณn y ansiedad.
Al realizar un seguimiento de la incidencia de depresiรณn y ansiedad en casi 389.185 adultos del Reino Unido durante 11 aรฑos, los investigadores descubrieron que quienes vivรญan en รกreas con mayor contaminaciรณn tenรญan mรกs probabilidades de sufrir episodios de depresiรณn y ansiedad, incluso cuando la calidad del aire estaba dentro de los lรญmites oficiales. La concentraciรณn mediana de contaminantes PM2,5 fue de 9,9 (9,3-10,6) ฮผg/m3. En Sรณller la cifra es de 9,28 (datos 2021).
Escribiendo en el Journal of the American Medical Association Psychiatry, los investigadores, de las universidades de Oxford y Beijing y el Imperial College London, han dicho que los resultados de su estudio sugirieron la necesidad de regulaciones mรกs estrictas para el control de la contaminaciรณn del aire.
A medida que aumentaba la contaminaciรณn del aire, tambiรฉn lo hacรญan los casos de depresiรณn y ansiedad. Sin embargo, las curvas de exposiciรณn-respuesta no fueron lineales, sino muestran pendientes mรกs pronunciadas en niveles mรกs bajos y tendencias estables en exposiciones mรกs altas, lo que sugiere que la exposiciรณn a largo plazo a niveles bajos de contaminaciรณn tenรญa la misma probabilidad de resultar en diagnรณsticos de depresiรณn que la exposiciรณn a niveles mรกs altos.
Por ejemplo, el riesgo aumenta cuando la concentraciรณn de PM2,5 sube de 8 a 10 ฮผg/m3, para despuรฉs mantenerse estable.
Significa que si en Sรณller logramos reducir el nivel solo un 20% podrรญamos eliminar el riesgo para la salud mental que supone la contaminaciรณn por partรญculas PM 2,5.
El estudio, publicado ayer, se titula"Exposiciรณn a largo plazo a mรบltiples contaminantes del aire ambiental y su asociaciรณn con incidentes de depresiรณn y ansiedad". (Long-term Exposure to Multiple Ambient Air Pollutants and Association With Incident Depression and Anxiety)

La nostra xarxa de sensors s'ha quedat reduรฏt a nomรฉs quatre i necessitem incorporar un mรญnim de quatre sensors nous per a cobrir el municipi. De la xarxa original de 12 nomรฉs queda un, i hem posat tres nous enguany.
La nova generaciรณ de monitors sรณn millors, perรฒ costen mรฉs tambรฉ.
>Mesuren partรญcules PM 10 i PM 2.5.
>Mesuren humitat relativa, pressiรณ i temperatura.
>Incorporen ara un petit calefactor que asseca l'aire. Normalment, hem de descartar dades quan la humitat relativa superi un 70% (cosa que ocorre sovint a les illes). Ara no caldrร descartar cap dada.
>Tรฉ una antena wifi. Ens proporciona mรฉs flexibilitat a l'hora de situar els sensors.
Per 117 euros (cadascun) podem incorporar aquests monitors a la nostra xarxa. Si vols colยทlocar un a la teva casa o negoci, posa't en contacte amb nosaltres. Tambรฉ es pot compartir la despesa entre diversos amics!
