e{0}}cov luam yeeb pov tseg yog tshuaj lom ntau dua li cov luam yeeb

Qee cov e- luam yeeb thiab cov cartridges tso tawm cov hlau uas muaj tshuaj lom ntau tshaj li cov qub -fashioned e- luam yeeb thiab txawm siab dua li cov luam yeeb. Cov kws tshawb fawb ntawm University of California, Davis, tau luam tawm ib qho kev tshawb fawb nyob rau hauv qhov tseeb tshaj tawm ntawm phau ntawv journal ACS Central Science, hais tias qib siab tshaj plaws uas tau tso tawm los ntawm e{4}} luam yeeb hauv ib hnub siv yog sib npaug rau kev haus luam yeeb ze li ntawm 20 packs ntawm cov luam yeeb ib txwm muaj.
Cov kws tshawb fawb tau hais tias txawm hais tias feem ntau cov e{0}} luam yeeb yog cov khoom tsis raug cai hauv Tebchaws Meskas, lawv tseem tau nthuav dav hauv khw. Nws cov neeg siv tseem ceeb yog cov tub ntxhais hluas thiab cov tub ntxhais hluas, uas tseem yog cov neeg nkag siab zoo tshaj plaws rau kev kis tus kab mob. Kev nqus tau qee yam hlau tseem ceeb ua rau muaj kev pheej hmoo ntawm mob qog noj ntshav, kab mob ua pa thiab puas hlwb.
Txoj kev tshawb no tau tshuaj xyuas xya lub e{0}} luam yeeb los ntawm peb hom loj. Cov kws tshawb fawb tau siv cov cuab yeej los simulate 500 txog 1,500 inhalations thiab kuaj pom qhov concentration ntawm cov hlau hauv cov pa luam yeeb. Lawv pom tias raws li tus naj npawb ntawm inhalations nce, qhov concentration ntawm chromium, npib tsib xee thiab antimony nyob rau hauv cov pa luam yeeb kuj nce.
Tsis tas li ntawd, cov kws tshawb fawb tau disassembled cov cuab yeej no thiab pom tias qee cov hlau muaj kuab lom los ntawm cov pa luam yeeb nws tus kheej, thiab ntau yam tau leached los ntawm cov khoom cua sov thiab cov hlau alloy. Cov hmoov txhuas thiab npib tsib xee tso tawm los ntawm cov hlau lead- cov khoom siv tooj liab alloy, npib tsib xee tso tawm los ntawm cov cua sov coils, thiab cov ntsiab lus siab ntawm antimony nyob rau hauv raw e- kua yog txhua qhov chaw ntawm cov kab mob.
Cov kws tshawb fawb tau soj ntsuam ntxiv txog kev pheej hmoo ntawm kev noj qab haus huv thiab pom tias qib nickel raug rau hauv peb lub cuab yeej thiab qib antimony raug rau hauv ob lub cuab yeej tau dhau qhov kev pheej hmoo ntawm kev mob qog noj ntshav; kev tso tawm cov nickel thiab txhuas hauv plaub lub cuab yeej kuj tau dhau qhov kev noj qab haus huv rau cov uas tsis yog - kab mob qog noj ntshav.
