Akatswiri a National Laboratory yotchedwa VI Lawrence ku Berkeley ku United States, ataphunzira mmene utsi wa ndudu zamagetsi zimapangidwira, anapeza kuti n'zovulaza thanzi la munthu monga ndudu wamba.
Osuta ena (komanso osasuta) amakhulupirira kuti ndudu za e-fodya ndizotetezeka ku thanzi lawo, kapena zosavulaza kwambiri kuposa ndudu wamba. Muzisuta nokha modekha ndipo musaganize kalikonse! Koma ziribe kanthu. Buku la ku America lofalitsidwa ndi Environmental Science & Technology lasindikiza kafukufuku wokhala ndi zowona komanso matebulo amankhwala omwe amatsimikizira kuti ndudu za e-fodya sizosiyana kwenikweni ndi zawamba.
“Ochirikiza ndudu za e-fodya amanena kuti kuchulukana kwa zinthu zovulaza m’mipangidwe yawo n’kochepa kwambiri kuposa pamene akusuta ndudu wamba. Lingaliro limeneli lingakhale loona kwa osuta odziŵa bwino lomwe amene sangathe kusiya kusuta. Koma izi sizikutanthauza kuti ndudu za e-fodya zilibe vuto. Ngati ndudu zanthawi zonse zimakhala zovulaza kwambiri, ndiye kuti ndudu za e-fodya ndi zoipa, "akutero wolemba kafukufuku Hugo Destailatz wa Lawrence Berkeley National Laboratory.
Pofuna kuphunzira momwe utsi umapangidwira mu ndudu za e-fodya, ndudu ziwiri za e-fodya zinatengedwa: zotsika mtengo zokhala ndi coil imodzi yotenthetsera ndi yokwera mtengo yokhala ndi zotentha ziwiri. Zinapezeka kuti mankhwala oopsa omwe ali mu utsiwo anawonjezeka kangapo panthawi yoyamba ndi yomaliza. Izi zidawoneka makamaka mu ndudu yamagetsi yotsika mtengo.
Pankhani ya manambala, mulingo wa acleroin, womwe umayambitsa kukwiya kwa mucous nembanemba wamaso ndi kupuma thirakiti, mu ndudu za e-fodya ukuwonjezeka kuchokera ku 8,7 mpaka 100 ma micrograms (mu ndudu wamba, mulingo wa acleroin ukhoza kuyambira 450- 600 micrograms).
Kuwononga kochokera ku ndudu yamagetsi kumawirikiza kawiri ikagwiritsidwanso ntchito. Zinapezeka kuti powonjezera ndudu zamagetsi, zinthu monga propylene glycol ndi glycerin zimagwiritsidwa ntchito, zomwe zimapanga mankhwala owopsa a 30, kuphatikizapo propylene oxide ndi glycidolom omwe sanatchulidwepo kale.
Nthawi zambiri, mawu omaliza ndi awa: kusuta sikungokhala kwanthawi yayitali (ndipo kwa nthawi yayitali!), Komanso kumavulaza kwambiri. Werengani zambiri za momwe mungasiyire kusuta PANO.
