Cov kws tshaj lij ntawm National Laboratory muaj npe tom qab VI Lawrence ntawm Berkeley hauv Tebchaws Meskas, tau kawm txog qhov muaj pes tsawg leeg ntawm cov pa luam yeeb hauv hluav taws xob, lawv pom tias lawv muaj kev phom sij rau tib neeg kev noj qab haus huv ib yam li luam yeeb.
Qee cov neeg haus luam yeeb (thiab cov neeg tsis haus luam yeeb ib yam nkaus) ntseeg tias e-luam yeeb muaj kev nyab xeeb rau lawv txoj kev noj qab haus huv, lossis tsawg kawg muaj teeb meem tsawg dua li luam yeeb. Haus luam yeeb koj tus kheej kom zoo thiab tsis txhob xav txog dab tsi! Tab sis txawm li cas los xij. Cov ntawv xov xwm Asmeskas Environmental Science & Technology tau tshaj tawm txoj kev tshawb fawb nrog cov lus tseeb thiab cov tshuaj tshuaj uas ua pov thawj tias e-luam yeeb yog qhov ua tau zoo tsis txawv ntawm cov khoom qub.
"Cov kws tshaj lij E-luam yeeb hais tias qhov concentration ntawm cov khoom tsis zoo hauv lawv cov muaj pes tsawg leeg yog qis dua thaum haus luam yeeb tsis tu ncua. Qhov kev xav no yuav muaj tseeb rau cov neeg haus luam yeeb uas tsis tuaj yeem txiav luam yeeb. Tab sis qhov ntawd tsis tau txhais hais tias e-luam yeeb yeej tsis muaj mob. Yog tias luam yeeb ib txwm muaj teeb meem loj, ces e-luam yeeb tsuas yog qhov phem xwb, "hais tias kev tshawb fawb sau Hugo Destailatz ntawm Lawrence Berkeley National Laboratory.
Txhawm rau kawm txog qhov muaj pes tsawg leeg ntawm cov pa luam yeeb hauv e-luam yeeb, ob lub e-luam yeeb tau raug coj mus rau: ib qho pheej yig nrog ib lub tshuab cua sov thiab ib qho kim nrog ob lub tshuab cua sov. Nws tau pom tias cov tshuaj txaus ntshai uas muaj nyob hauv cov pa luam yeeb tau nce ntau zaus thaum thawj zaug thiab zaum kawg puff. Qhov no yog tshwj xeeb tshaj yog pom nyob rau hauv ib tug pheej yig hluav taws xob luam yeeb.
Nyob rau hauv cov nqe lus ntawm cov zauv, qib ntawm acleroin, uas ua rau irritation ntawm mucous daim nyias nyias ntawm lub qhov muag thiab ua pa ib ntsuj av tau, nyob rau hauv e-luam yeeb nce los ntawm 8,7 mus rau 100 micrograms (nyob rau hauv cov luam yeeb li niaj zaus, theem ntawm acleroin muaj peev xwm nyob ntawm 450- 600 micrograms).
Kev puas tsuaj los ntawm cov luam yeeb hluav taws xob ob npaug thaum nws rov siv dua. Nws muab tawm tias thaum refueling cov luam yeeb hauv hluav taws xob, cov khoom siv xws li propylene glycol thiab glycerin, uas tsim ntau tshaj 30 cov tshuaj lom neeg txaus ntshai, suav nrog yav dhau los tsis tau hais txog propylene oxide thiab glycidolom.
Feem ntau, cov lus xaus yog qhov no: kev haus luam yeeb tsis yog tsuas yog tsis zam (thiab ntev!), tab sis kuj muaj teeb meem heev. Nyeem ntxiv txog yuav ua li cas txiav luam yeeb NO.
