In the last year most frequently performed measurements are that of particles with a diameter of 10 &micro;m (PM 10 ) and 2.5 &micro;m (PM 2.5 ), which are the most harmful to health.
V zadnjih letih se najpogosteje izvajajo meritve delcev s premerom 10 &micro;m (PM 10 ) in 2,5 &micro;m (PM 2,5 ), ki so najbolj škodljivi za zdravje.
