Hauv Tebchaws Meskas, cov kws tshawb fawb tau tsim cov txheej txheem los txiav txim siab txog qib ntawm toxicity ntawm e-kua. Yog li ntawd, qee cov khoom xyaw uas siv rau hauv kev tsim cov e-kua kua muaj tshuaj lom ntau dua li lwm tus.
DAIM NTAWV THOV KEV PAB CUAM!
Cov kws tshawb fawb ntawm North Carolina Tsev Kawm Ntawv Tshuaj Kho Mob hauv Tebchaws Meskas tau tsim cov txheej txheem rau kev txiav txim siab txog qib tshuaj lom ntawm e-kua. Lawv txoj kev kawm muaj nyob rau ntawm PLOS.
E-kua yog tsim los ntawm ob qho khoom xyaw tseem ceeb: propylene glycol thiab zaub glycerin. Ntxiv rau qhov no yog nicotine thiab flavorings. Cov kws tshawb fawb tom qab ntawd tau tsim ib qho kev ntsuam xyuas sai rau cov tshuaj lom ntawm e-kua.
Ua li no, lawv nthuav tawm kab lis kev cai ntawm tib neeg lub hlwb mus rau vapor ntawm cov kua sib txawv. Cov hlwb ces stains. Yog lawv tig ntsuab, lawv ciaj sia, liab yog lawv tuag. Cov kev loj hlob ntawm tes kuj tau pom, yog li qhov qis dua, qhov muaj kuab lom ntau dua e-kua.
Ob qho khoom xyaw tseem ceeb hauv cov kua no tau suav tias yog tsis muaj tshuaj lom thaum noj qhov ncauj, tab sis thaum nqus tau cov cell loj hlob tau txo qis. Cov kws tshawb fawb kuj pom tau hais tias nyob ntawm cov tshuaj tsw qab, cov khoom xyaw sib txawv heev. Feem ntau hais lus, cov khoom xyaw ntau dua, qhov ntau dua qhov toxicity ntawm cov kua. Lub xub ntiag ntawm vanillins los yog cinnamon nyob rau hauv muaj pes tsawg leeg kuj txuam nrog ntau dua toxicity qhov tseem ceeb.
Txhawm rau kom yooj yim tshaj tawm cov txiaj ntsig no, pab pawg tshawb fawb tau teeb tsa ib qho database ntawm cov khoom xyaw thiab cov ntaub ntawv ntawm toxicity ntawm e-kua dawb muaj. Lawv cia siab tias txoj haujlwm no yuav ua rau nws muaj peev xwm, yav tom ntej, kom tswj tau cov khoom ntawm e-kua zoo dua.
