Raws li Franceinfo, ib txoj kev tshawb fawb los ntawm Fab Kis Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Tshawb Fawb Kev Kho Mob (Inserm) qhia tau hais tias kev raug rau qee yam pa phem thaum yug los yuav ua rau muaj kev pheej hmoo rau menyuam yaus mob leukemia. Cov kev tshawb pom tau tsis ntev los no tau luam tawm hauv phau ntawv xov xwm kev kawm "Environmental Health".
Nov yog thawj zaug uas pab pawg tshawb fawb Inserm tau tshawb xyuas qhov cuam tshuam ntawm cov teeb meem tsis zoo ntawm cov pa phem los ntawm kev tsheb khiav ntawm txoj kev pheej hmoo ntawm cov menyuam yaus leukemia. Txoj kev tshawb no tsom los ntsuas qhov ntsuas ntawm qhov tshwm sim ntawm cov menyuam yaus raug rau cov pa phem hauv tsheb thiab tshuaj xyuas seb qhov kev raug mob no ua rau muaj kev pheej hmoo mob qog noj ntshav tom qab lub neej. Case-Kev tswj xyuas tau pom tias "kev pheej hmoo ntau dhau" rau cov menyuam yaus uas muaj tus kabmob no tau tshaj 12%, thaum qhov sib txawv ntawm kev nyob hauv nroog thiab nyob deb nroog tsis tseem ceeb.
Cov kws tshawb fawb tau tsom mus rau kev tshuaj xyuas peb cov pa phem: cov khoom tsis zoo, nitrogen dioxide, thiab cov pa roj carbon dub (cov pa luam yeeb), thiab hla - hais txog cov ntaub ntawv. Ua ntej, lawv tau muab piv rau 817 cov menyuam yaus uas muaj mob qog noj ntshav nrog 12,000 tus menyuam noj qab nyob zoo. Tom qab ntawd, lawv txheeb xyuas seb cov menyuam no puas tau yug los hauv nroog loj, nruab nrab - lub nroog loj, lossis thaj chaw nyob deb nroog.
Aurélie Danjou, kws kho mob kis kab mob ntawm Inserm thiab ib qho ntawm cov kws tshawb fawb ua thawj coj, tau hais tias, "Peb txoj kev tshawb fawb txhawb nqa qhov kev xav tias kev ua pa phem hauv perinatal ua lub luag haujlwm hauv kev loj hlob ntawm cov menyuam yaus mob leukemia, tshwj xeeb tshaj yog kev sib koom ua ke ntawm cov teeb meem tsis zoo (PM2.5) thiab mob qog noj ntshav qog ntshav."

Cov peev txheej no suav nrog ntoo- hluav taws xob hluav taws xob thiab kev ua qias tuaj. Txoj kev tshawb no qhia tias cov pa roj carbon dub (tsim pa taws) cuam tshuam nrog cov peev txheej no tuaj yeem ua lub luag haujlwm tseem ceeb. Cov pa phem no tsim los ntawm kev sib txuas tuaj yeem ua rau muaj kev pheej hmoo ntawm mob leukemia los ntawm 80%.
