Kafukufuku waposachedwapa wasonyeza kuti okwera ndege nthawi zambiri amakumana ndi kuipitsidwa kwakukulu kwa tinthu tating'onoting'ono (UFP) akamayendetsa taxi komanso pabwalo la ndege. Tinthu tating'onoting'ono tomwe timakhala tating'onoting'ono kwambiri, tomwe ndi tating'onoting'ono tosakwana 100 nanometers (0.1 micrometers), tingathe kudutsa mosavuta zosefera wamba ndikulowa mkati mwa mapapo, zomwe zingayambitse mavuto azaumoyo kwa nthawi yayitali.
Ngakhale kuti masks a N95 amapangidwira makamaka kusefa tinthu tating'onoting'ono tokwana ma micrometer 0.3 (300 nanometers), amaperekabe chitetezo chokwanira ku tinthu tating'onoting'ono kwambiri. Chifukwa cha mphamvu ya kuyenda kwa Brownian, masks a N95 amatha kugwira tinthu tating'onoting'ono bwino kwambiri kuposa momwe amayembekezera.
Kuchuluka kwa tinthu tating'onoting'ono kwambiri kumakhala kwakukulu kwambiri panthawi yoyendetsa ndege, makamaka ndege ikangokhala chete kapena kumbuyo kwa ndege ina. Mainjini a ndege amatulutsa zinthu zosiyanasiyana zoipitsa, kuphatikizapo tinthu tating'onoting'ono (PM), zinthu zachilengedwe zosinthasintha (VOCs), ndi nthunzi yamafuta. Zinthu zimenezi zoipitsa, makamaka ma VOC, zimatha kulowa m'nyumba, zomwe zimawononga kwambiri mpweya panthawi yonyamuka ndi kutera.
Ngakhale kuti milingo ya PM2.5 imayesedwa nthawi zambiri m'mabwalo a ndege, tinthu timeneti sitigwirizana mwachindunji ndi tinthu ta ultrafine, zomwe zimakhala zovuta kuzizindikira. PM2.5 nthawi zambiri imagwiritsidwa ntchito ngati muyeso wosalunjika wa tinthu ta ultrafine, chifukwa kupezeka kwawo kumalumikizidwa ndi kuchuluka kwa tinthu tating'onoting'ono. Komabe, zoopsa zaumoyo zokhudzana ndi tinthu ta ultrafine zimagwirizana kwambiri ndi kuchuluka kwawo ndi malo awo kuposa kulemera kwawo.
Ngakhale kuti masks a N95 si abwino kwambiri posefa tinthu tating'onoting'ono tomwe tili m'mlengalenga, amaperekabe chitetezo chogwira mtima ku zinthu zosiyanasiyana zoipitsa mpweya. Kuvala mask ya N95 mukakwera taxi, kunyamuka, komanso kutera kungathandize kuchepetsa kukhudzana ndi tinthu tating'onoting'ono komanso ma VOC oopsa. Kwa okwera omwe ali ndi vuto lalikulu ndi kuipitsidwa kwa mpweya, monga omwe amamva nseru kapena zizindikiro za kupuma, njira yosavuta iyi ingapereke chitetezo chofunikira ku kuipitsidwa kwakukulu kwa tinthu tating'onoting'ono tomwe timapezeka panthawiyi yoyenda pandege.
