Pollution is an everyday topic in European news these days. On the 24th of JanuaryLondon reached higher pollution values then Beijing did the same day. Stuttgart triggered the „Smog Alert“ (people are asked to use public transport to a reduced fair or to carpool) 17 times in January 2017.
According to a statistic of the WHO one out of seven people (9 million) died because of pollution 2012.1 According to Pure Earth a non-Profit environmental organization children who live in the words most polluted places are borne with defects or have lost up to 40iQ points.2
But what amount of pollution is dangerous ?
How polluted is the air breath in exactly this moment ?
This project tries to answer these questions.
But first to understand the subjected topic completely it is important to know that there are two different „types“ of Pollution widely measured.
These particles include dust, pollen, mold spores and other particles smaller than 10µm.
50% of these particles are not filtered by your nose and throat ending up in your lungs.
With every increase of 10 μg/m3 in PM10, the risk of lung cancer rises by 22%.
These smaller particles include combustion particles, organic compounds, metals and other particles smaller than 2.5µm. 50% of these particles are so small that they pass through the lungs and affect other organs directly.
PM2,5 can penetrate the lungs deeper. An increase by 10 μg/m3 augments the risk of lung cancer by 36%.
The Pollution Sensor
This project gives you an easy and simple solution to track the concentration of PM10 and PM2,5 particles in your everyday surrounding.(e.g.at university, at work, at home ,on your tennis court …) The GUI enables you to see how high the actual concentration is. Additional information such as the average of concentration measured in selected cities around Europe, EU and WHO limits are displayed. So you can classify your values directly and get a feeling for the amount of pollution you are living in.
If you want to inform yourself further, additional information about the different types and risks is displayed on the screen.
