Particle PM2.5 Saib xyuas lub Hoobkas muab kev pabcuam
NTA
Particulate matter (PM) yog ib qho kev ua qias tuaj, uas yog tsim los ntawm ntau txoj hauv kev uas tuaj yeem muab faib ua cov txheej txheem siv tshuab lossis tshuaj lom neeg.Kev lig kev cai, kev tshawb fawb ib puag ncig tau muab faib ua ob pawg tseem ceeb PM10 thiab PM2.5.
PM10 yog qhov nruab nrab ntawm 2.5 thiab 10 microns (micrometers) nyob rau hauv txoj kab uas hla (ib tug tib neeg cov plaub hau yog hais txog 60 micron inch).PM2.5 yog cov khoom me dua 2.5 microns.PM2.5 thiab PM10 muaj cov khoom sib txawv thiab tuaj yeem los ntawm ntau qhov chaw.Qhov me me ntawm qhov ntev nws tuaj yeem nyob twj ywm rau hauv huab cua ua ntej daws.PM2.5 tuaj yeem nyob hauv huab cua los ntawm ntau teev mus rau lub lis piam thiab taug kev deb heev vim nws me thiab sib dua.
PM2.5 tuaj yeem nkag mus rau hauv qhov tob tshaj plaws (alveolar) feem ntawm lub ntsws thaum sib pauv roj tshwm sim ntawm huab cua thiab koj cov ntshav.Cov no yog cov khoom txaus ntshai tshaj plaws vim hais tias cov alveolar feem ntawm lub ntsws tsis muaj peev xwm tshem tau lawv thiab yog tias cov khoom yog dej soluble, lawv tuaj yeem nkag mus rau hauv cov ntshav hauv feeb.Yog tias lawv tsis yog dej soluble, lawv nyob hauv qhov alveolar ntawm lub ntsws ntev.Thaum cov khoom me me nkag mus tob rau hauv lub ntsws thiab nkag mus rau qhov no tuaj yeem ua rau mob ntsws, emphysema thiab / lossis mob ntsws cancer hauv qee kis.
Cov teebmeem tseem ceeb uas cuam tshuam nrog kev cuam tshuam rau cov khoom me me tuaj yeem suav nrog: kev tuag ntxov ntxov, ua rau mob ntsws ua pa thiab mob plawv (xws li kev nkag mus rau hauv tsev kho mob thiab chav xwm txheej ceev, kev tsis tuaj kawm ntawv, hnub poob haujlwm, thiab hnub txwv kev ua si) ua rau mob hawb pob, mob ua pa nyuaj. Cov tsos mob, mob bronchitis, txo lub ntsws ua haujlwm thiab nce myocardial infarction.
Muaj ntau ntau yam ntawm cov pa phem hauv peb lub tsev thiab chaw ua haujlwm.Ib qho los ntawm sab nraud suav nrog cov chaw tsim khoom, chaw tsim kho, qhov chaw combustion, paj ntoos, thiab ntau lwm yam.Cov khoom no kuj tsim los ntawm txhua yam kev ua si sab hauv tsev xws li kev ua noj, taug kev hla cov ntaub pua plag, koj cov tsiaj, rooj zaum lossis txaj, cua txias thiab lwm yam. Txhua qhov kev txav los yog kev vibration tuaj yeem tsim cov khoom hauv huab cua!
