Posachedwapa, zimphona ziwiri zazikuluzikulu za fodya, PMI ndi BAT, motsatana zidasindikiza zofufuza m'magazini apamwamba azachipatala apadziko lonse lapansi.Zotsatira zafukufuku zikuwonetsa kuti fodya watsopano monga e-fodya ndi mankhwala osawotcha ndi owopsa komanso owopsa kuposa ndudu zachikhalidwe, ndipo amatha kuchepetsa kwambiri mphamvu ya kupuma.kuvulaza.
Pamene kuzindikira kwa anthu za kuopsa kwa kusuta kukukulirakulira, ndudu za e-fodya zikuzindikiridwa mowonjezereka ngati m'malo mwa ndudu, koma zotsatira za nthawi yaitali za kusakaniza konunkhira kwa e-fodya ndi utsi wa ndudu pa osuta zikuyenera kufufuzidwa mowonjezereka.Posachedwapa, PMI Philip Morris International adafalitsa lipoti la kafukufuku "Kuwunika kwa poizoni wa fodya wa ndudu ndi aerosols kuchokera ku zosakaniza za kukoma: Kuphunzira kwa masabata a 5 mu A / J mbewa" mu British Journal of Toxicology "Journal of Applied Toxicolog", kufotokoza mwatsatanetsatane. za mitu yofananira Masitepe a kafukufuku ndi zotsatira.
Poyesera, mbewa zamphongo za 87 ndi 174 nulliparous ndi mbewa zazikazi zapakati zidasankhidwa mwachisawawa kumagulu oyesera a 9, ndipo adayesedwa mumlengalenga, utsi wa ndudu, ndi ma aerosols a e-fodya okhala ndi mitundu itatu yosiyanasiyana ya zokometsera, zapamwamba, zapakati, ndi zochepa. .Kuwonetsedwa kwa maola 6 patsiku, masiku asanu pa sabata, kwa milungu isanu kumatsatiridwa ndi necropsy, kulemera kwa ziwalo ndi kuwunika kwa histopathological.
Zotsatira zomaliza zoyeserera zidawonetsa kuti poyerekeza ndi kukhudzana ndi utsi wa ndudu, mbewa zomwe zimawululidwa ndi e-fodya aerosols ndi opanda zokometsera zinalibe kusintha kwakukulu mu ziwalo zopuma, mphuno, ndi laryngeal epithelial tissues, zomwe zimasonyeza kuti e-fodya The sol imakhala yochepa kwambiri. kwa minofu ndi ziwalo zogwirizana.Zotsatira zoyesera zinatsimikiziranso kuti, poyerekeza ndi ndudu zachikhalidwe, ndudu za e-fodya zimatha kuchepetsa kwambiri kutupa m'mapapo, komanso kuwonongeka kwa epithelium ya mphuno, mmero ndi trachea.
BAT British American Fodya inafalitsa pepala lofufuzira lotchedwa "An Experimental Analytical and In Vitro Approach to Bridge Pakati pa Mitundu Yosiyanasiyana ya Fodya Yotentha" mu "Zopereka ku Fodya & Nicotine Research" magazini yasayansi, ndipo adachita kafukufuku pa THP (HNB products) Toxicology. kuyesa.Pakuyesaku, utsi wa aerosol ndi ndudu wamitundu isanu ya THP ndi THP imodzi yoyambira idagwiritsidwa ntchito ngati malo oyesera, ndipo cytotoxicity idawunikidwa ndi kuthekera kwa maselo am'mapapo amunthu.Zotsatira zinawonetsa kuti machitidwe onse a cytotoxic mu gulu la THP anali otsika ndi 95% kuposa omwe anali mu gulu la utsi wa ndudu, ndipo panalibe kusiyana kwakukulu kwa kawopsedwe pakati pa THP zisanu zosiyana ndi THP yoyambirira.
Kafukufukuyu adatsimikiza kuti chitukuko ndi kuperekedwa kwa fodya wina ndi chikonga chikukula mofulumira, ogula akuvomereza kwambiri zinthu zatsopano monga THP, ndipo chitetezo chake ndi chiwopsezo monga gawo la kuwunika kwa poizoni ndizoyenera kuyang'anira makampani.Pokhapokha pamene mankhwalawo akwaniritsa miyezo (kuphatikizapo machitidwe a batri) angagwire bwino ntchito yake ngati njira yaumoyo wa anthu.
