Phau Ntawv Qhia Txog Kev Yuav Cov Cuab Yeej Cuab Yeej Hauv Kev Ua Lag Luam
1. Particle muaj kuab paug
Particle teeb meem muaj kuab paug yog peb hom PM particle pollution. Nws yog tsim los ntawm cov khoom raug tshem tawm ntawm qhov ntau thiab tsawg xws li PM{{0}}.1, PM0.3, PM1.0, PM2.5, thiab PM10. Cov ntsiab lus tshwj xeeb ntawm cov khoom yog qhov nyuaj, tsis yog tsuas yog los ntawm lub tsheb tso pa tawm los ntawm ntau qhov chaw xws li lub Hoobkas emissions thiab qoob loo straw hlawv. Yog li ntawd, nws yog collectively hu ua cov pa phem particulate.
Tam sim no, yuav luag tag nrho cov khoom lag luam hauv tsev ntawm cov tshuab cua lim lossis cov cuab yeej siv Plantower's laser particle sensor tov los ntsuas qhov ntsuas tsis xws li PM2.5 thiab PM10 hauv huab cua, thiab qhov ntsuas ntau yog nyob nruab nrab ntawm 0-999ug/m³.
2. Organic compound pollution
Tshooj lus tsis hloov pauv cov organic yuav tsum nkag siab txog cov ntsiab lus hauv qab no:
Thawj yog VOC, cov ntawv luv ntawm VOC yog hais txog cov organic tsis muaj zog. VOC yog cov lus Askiv luv ntawm volatile organic compound (volatile organic compoundS). Feem ntau peb xa mus rau VOC raws li volatile organic tebchaw, tab sis lub ntsiab lus los ntawm lub foundations ntawm ib puag ncig tiv thaiv yog hais txog ib chav kawm ntawm active volatile organic tebchaw hu ua VOC, uas npog tag nrho cov volatile organic tebchaw uas ua rau raug mob.
3. Formaldehyde muaj kuab paug
Raws li kev tshawb fawb hauv tsev, qhov concentration ntawm formaldehyde nyob rau hauv cov tsev tshiab hauv Suav nroog yog {{0}}.18 mg/m³, uas tshaj lub teb chaws tus qauv (0.10 mg/m³) tshaj tawm los ntawm Ministry of Health. Ntau yam khoom siv hauv tsev kho kom zoo nkauj txhua hnub, xws li cov laug cam, cov xim pleev xim, tshuaj fiber ntau fabrics, thiab lwm yam, yog cov khoom tseem ceeb ntawm formaldehyde sab hauv tsev. Thaum cov ntsiab lus ntawm formaldehyde ntau tshaj qhov muaj txiaj ntsig zoo, nws yuav ua rau tib neeg lub qhov muag thiab cov mucous daim nyias nyias ntawm txoj kev ua pa, ua rau kua muag, mob caj pas, txham thiab lwm yam tsos mob, thiab tuaj yeem ua rau mob hawb pob. Yog li ntawd, rau cov chav tsev tshiab, yuav ua li cas saib xyuas thiab tswj cov concentration ntawm formaldehyde yog ib qho teeb meem ntawm kev txhawj xeeb rau txhua tus.
Tam sim no, kev tshawb nrhiav formaldehyde hauv tsev feem ntau siv cov tshuaj electrochemical sensor ntawm British Dart Company, qhov kev daws teeb meem tuaj yeem ncav cuag qib PPB, thiab qhov kev kuaj pom qhov yuam kev yog 0.01-0.001mg/m³.
4. Cov pa roj carbon dioxide concentration
Cov pa roj carbon dioxide, ib feem ntawm cov huab cua thiab ib lub tsev cog khoom roj, feem ntau raug saib xyuas raws li ib qho ntawm cov pa phem. Thaum cov ntsiab lus ntawm cov pa roj carbon dioxide nyob rau hauv cov huab cua yog ib txwm, tsis muaj kev puas tsuaj rau tib neeg lub cev, tab sis thaum nws ntau tshaj ib qho concentration, nws yuav cuam tshuam rau tib neeg lub cev ua pa. Txhua tus uas tau kawm chemistry hauv tsev kawm ntawv theem nrab paub tias carbon dioxide yaj hauv dej los tsim cov pa roj carbonic acid. Yog li ntawd, thaum cov pa roj carbon dioxide concentration nce, yog li cov carbonic acid concentration hauv cov ntshav, thiab acidosis tuaj yeem tshwm sim.
Qhov concentration ntawm carbon dioxide nyob rau hauv ib txwm ib puag ncig yog 400ppm, thiab feem ntau nws yog nyob ib ncig ntawm 500 mus rau 700ppm thaum tsis muaj ib tug nyob rau hauv chav tsev. Nyob rau lub caij ntuj no, vim muaj cua sov thiab kev txuag hluav taws xob, lub qhov rooj thiab qhov rais feem ntau raug kaw, thiab cov concentration ntawm carbon dioxide kuj tseem yuav nce ntxiv rau lub sijhawm no. Thaum cov pa roj carbon dioxide concentration nce mus txog 1000ppm, tib neeg yuav hnov dua thiab inattentive; thaum nws nce mus txog 1500-2000ppm, tib neeg cov tsos mob yuav pom tseeb dua, thiab tib neeg yuav hnov qhov ua tsis taus pa thiab kiv taub hau. Yog li ntawd, nws tseem yuav tsum tau saib xyuas qhov concentration ntawm cov pa roj carbon dioxide nyob rau hauv cov huab cua sab hauv, tshwj xeeb tshaj yog rau cov tsev neeg nrog cov kiv cua tshiab.
Tam sim no, cov pa roj carbon dioxide sensor feem ntau siv cov infrared carbon dioxide sensor daws teeb meem ntawm Sweden's Senseair, nrog rau kev tshawb pom qhov tseeb ntawm 30-50ppm thiab kev ntsuas ntau ntawm 400-9999ppm.
