Amadirishya yanduye yanduye ntaho atandukaniye nibisanzwe byamadirishya.Ariko bitandukanye na ecran zisanzwe, iki gice cyoroshye cya firime cyuzuyemo ibyobo bitagaragara kumaso. Buri santimetero kare ishobora kuba yuzuyemo amamiriyoni yubunini bwa molekile.Molecular- ibipimo binini byemerera molekile gusa kunyuramo, bityo uduce duto nka PM2.5, amabyi arashobora guhagarikwa na firime yoroheje bitagize ingaruka kumyuka ya molekile nka dioxyde de carbone.Ikoreshwa nimpeshyi nimpeshyi
