PM2,5 and PM10

PM2.5 and PM10 are inhalable particles with a diameter ≤ 2.5 and ≤10 µm, respectively. PM2.5 is measured continuously in Sakajärvi and Laurajärvi and PM10 is measured continuously in Sakajärvi, Laurajärvi and Liikavaara. Starting in the summer of 2021, PM2.5 and PM10 will also be measured in Keskijärvi. In Sakajärvi, Laurajärvi and Keskijärvi optical measurement takes place, while in Liikavaara it is still measured m.h.a. filters, but in the autumn of 2021 it will be replaced with an optical measuring equipment, as that method makes it possible to follow up measurement results minute by minute instead of just daily means.

Current results for 2021 are presented below.
