WHY ULTRA-FINE PARTICLES ARE DANGEROUS FOR US?
Large particles are mostly captured
by mucous membranes of nose and
throat.
Inhalable particles < 10 µm (called
PM10) can enter the lungs.
Fine particles < 2,5 µm (called PM2.5)
can penetrate into alveoles.
Ultrafine particles < 0,1 µm (100
nm) can be absorbed directly into
bloodstream and are the most
dangerous ones, according to WHO.
