Qhov sib txawv tseem ceeb ntawm aerosol thiab cov khoom me me yog lub sij hawm aerosol yog hais txog cov khoom ntawm cov khoom raug tshem tawm thiab cov pa ib puag ncig thaum lub sij hawm cov khoom seem yog hais txog cov khoom raug tshem tawm lossis cov kua hauv huab cua.
Ob nqe lus aerosol thiab cov khoom siv qhia txog cov khoom hauv huab cua. Ib qho aerosol yog ib qho kev sib sau ntawm ob qho tib si thiab huab cua thaum cov khoom me me tsuas yog cov khoom raug tshem tawm hauv huab cua. Cov khoom nyob rau hauv ob daim ntawv no yog hu ua "particulates", thiab lawv tuaj yeem tsim kev puas tsuaj thaum nqus tau rau hauv lub ntsws.
Aerosol yog dab tsi?
Aerosol yog ib qho kev ncua ntawm cov khoom siv los yog cov kua dej hauv huab cua lossis lwm yam roj. Aerosols yog ntuj los yog tib neeg tsim. Qee cov aerosols ntuj muaj xws li huab cua, huab cua, plua plav, hav zoov exudates, thiab geyser chav, thaum qee qhov piv txwv ntawm tib neeg tsim aerosols suav nrog cov pa phem thiab pa taws. Hauv ib qho aerosol, qhov ntev ntawm cov kua los yog cov khoom siv feem ntau yog tsawg dua 1 micrometer. Cov ntaub ntawv raug tshem tawm vim muaj cov khoom loj loj nrog rau qhov nrawm nrawm. Hauv kev siv ntau, aerosol yog tshuaj tsuag uas xa cov khoom siv los ntawm lub thawv.
Daim duab 01: Aerosol
Aerosols feem ntau sib txawv hauv lawv qhov sib txawv. Muaj monodispersed thiab polydispersed aerosols. Lub monodispersed aerosol tuaj yeem tsim tau yooj yim hauv chav kuaj, thiab nws muaj cov khoom sib xws nrog qhov loj me. Ib qho polydispersed aerosol, ntawm qhov tod tes, muaj cov khoom nrog ntau qhov ntau thiab tsawg. Yog tias cov aerosol muaj cov tee dej, peb tuaj yeem pom tias cov tee dej no yuav luag txhua lub voj voog.
Muaj ntau daim ntawv thov ntawm aerosols xws li kuaj aerosols rau ntsuas ntsuas, ua kev tshawb fawb, xa cov deodorants, xim, rau kev ua liaj ua teb, kev kho mob hauv cov kab mob ua pa, kev txhaj tshuaj roj, thiab lwm yam.
Dab tsi yog Particulate Matter?
Particulate matter or particulates is the solid particles or liquid droplets suspended in air. Cov khoom no yog microscopic; lawv tuaj yeem yog ntuj lossis anthropogenic. Qee qhov piv txwv ntawm cov huab cua muaj xws li thoracic thiab respirable hais, inhalable coarse hais, thiab lwm yam. Cov hais no tsis ntau tshaj 10 micrometers loj.

Cov khoom muaj pes tsawg leeg nyob ntawm qhov chaw uas cov khoom yog tsim los ntawm. Qee cov khoom tuaj yeem tuaj rau hauv qhov chaw ntawm volcanic eruptions, plua plav cua daj cua dub, hluav taws kub hav zoov, tshuaj tsuag dej hiav txwv, thiab lwm yam. Feem ntau, cov khoom me me thiab sib zog nyob hauv huab cua ntev. Cov khoom loj loj yuav nyob ntawm qhov kev txiav txim ntawm lub ntiajteb txawj nqus.
Qhov txawv ntawm Aerosol thiab Particulate Matter yog dab tsi?
Ob nqe lus aerosol thiab cov khoom siv piav qhia txog cov khoom hauv huab cua. Qhov sib txawv tseem ceeb ntawm aerosol thiab cov khoom me me yog aerosol hais txog cov khoom ntawm cov khoom raug tshem tawm thiab cov pa ib puag ncig, thaum cov khoom me me yog hais txog cov khoom raug tshem tawm lossis cov kua hauv huab cua.
Hauv qab infographic qhia ntau cov ntsiab lus ntawm qhov sib txawv ntawm aerosol thiab cov teeb meem me me.
Summary – Aerosol vs Particulate Matter
Aerosol yog ib qho kev ncua ntawm cov khoom siv los yog cov kua dej hauv huab cua lossis lwm yam roj. Particulate matter los yog particulates yog hais txog cov khoom me me los yog cov kua dej uas tau muab tshem tawm hauv huab cua. Qhov sib txawv tseem ceeb ntawm aerosol thiab cov khoom me me yog qhov aerosol yog ib qho kev sib sau ntawm cov khoom raug tshem tawm thiab cov pa ib puag ncig, hos cov khoom me me yog cov khoom raug tshem tawm lossis cov khoom ua kua hauv huab cua.
