< h2 > Particle Matter sizes </ h2 >
< p >< b > There is no healthy level of pollution .</ b > Particle matter ( PM ) are defined in two different sizes : PM 2.5 which represents particle sizes smaller than 2.5 & #xB5;m or less than 1/20th of the diameter of a human hair and PM 10 which represents particle sizer smaller than 10 µm or 1/5th of the diameter of a human hair.</p>
< p > The < a href = " https://www.who.int/news-room/fact-sheets/detail/ambient-(outdoor)-air-quality-and-health " target = " _blank " > WHO </ a > is providing more details on their website regarding particle matter and their health implications . On < a href = " https://en.wikipedia.org/wiki/Particulates " target = " blank " > Wikipedia </ a > there are some interesting links to studies for further reading .</ p >

< h3 > PM 2.5 </ h3 >
< p > Particle matter sizes smaller than 2.5 & #xB5;m are the most problematic as these particles will find their way through the lungs into the bloodstream.</p>
< p > The WHO Air quality guideline values set a 25 & #xB5;g/m³ 24-hour average as an upper level threshold. In the 10 days overview you can see:</p>
< p > Green : Daily average exposure below 25 & #xB5;g/m³<br>
Red : Daily average exposure above 25 & #xB5;g/m³</p>

< h3 > PM 10 </ h3 >
< p > The threshold for the daily average PM 10 exposure is set to 50 & #xB5;g/m³ by the WHO. Particles this size can penetrate and lodge deep inside the lungs but are too big to enter the blood stream. For this reason the threshold is higher.</p>
