Ubushakashatsi buherutse gukorwa bwagaragaje ko abagenzi bo mu kirere bakunze guhura n’umwanda mwinshi cyane w’udukoko twa ultrafine (UFP) mu gihe cyo gutwara tagisi no ku kibuga cy’indege. Utwo dukoko twa ultrafine, duto cyane kurusha nanometero 100 (mikorometero 0.1), dushobora kunyura mu byuma bisanzwe byoroshye no kwinjira mu bihaha, bikaba byatera ibyago by’ubuzima mu gihe kirekire.
Nubwo udupfukamunwa twa N95 twagenewe ahanini kuyungurura uduce duto cyane nka mikorometero 0.3 (nanometero 300), turacyatanga uburinzi buhambaye ku duce duto cyane. Bitewe n'ingaruka z'uburyo Brownian motion, udupfukamunwa twa N95 dushobora gufata n'uduce duto neza kurusha uko byari byitezwe.
Ubwinshi bw'uduce duto cyane cyane mu gihe cyo guhaguruka mu ndege, cyane cyane iyo indege ikora akazi kayo cyangwa inyuma y'indi ndege. Moteri z'indege zisohora uruvange rw'imyanda ihumanya, harimo uduce duto (PM), ibintu bihindagurika mu kirere (VOCs), n'umwuka uhumanya ikirere. Iyi myanda, cyane cyane VOCs, ishobora kwinjira mu nzu, ikangiza cyane ubwiza bw'umwuka mu gihe cyo guhaguruka no kugwa.
Nubwo urugero rwa PM2.5 rukunze gupimwa ku bibuga by'indege, utwo duce ntabwo dufitanye isano itaziguye n'uduce twa ultrafine, kuko bigoye kubibona. PM2.5 ikunze gukoreshwa nk'igipimo kitaziguye ku duce twa ultrafine, kuko kuba turiho bifitanye isano n'ubwinshi bw'uduce duto. Ariko, ingaruka mbi ku buzima zijyanye n'uduce twa ultrafine zifitanye isano rya bugufi n'umubare watwo n'ubuso bwatwo kuruta uburemere bwatwo.
Nubwo udupfukamunwa twa N95 tudakora neza mu kuyungurura uduce duto cyane, duracyatanga uburinzi bwiza ku bihumanya ikirere bitandukanye. Kwambara agapfukamunwa ka N95 mu gihe cyo gutwara tagisi, guhaguruka no kugwa ku butaka bishobora gufasha kugabanya guhura n’uduce duto ndetse n’udukoko twangiza ikirere. Ku bagenzi bakunze kwanduzwa cyane n’umwuka, nk’abagira isesemi cyangwa ibimenyetso by’ubuhumekero, ubu buryo bworoshye bwo kwirinda bushobora gutanga uburinzi bw’ingirakamaro ku rugero rwo hejuru rw’uduce duto cyane tubaho muri ibi bihe byo mu ndege.
