1. VOC
VOC cov khoom xa mus rau cov organic uas tsis muaj zog. VOC stands rau Volatile Organic compoundS. VOC hauv kev nkag siab dav dav yog cov lus txib ntawm cov khoom siv hluav taws xob; Tab sis lub ntsiab lus ntawm kev tiv thaiv ib puag ncig yog hais txog ib yam ntawm cov organic tebchaw uas tsis muaj zog, uas tuaj yeem tsim kev puas tsuaj.
Qhov tseeb, VOCs tuaj yeem muab faib ua ob pawg:
Ib qho yog lub ntsiab txhais ntawm VOC, tsuas yog dab tsi yog volatile organic tebchaw los yog nyob rau hauv tej yam kev mob yog volatile organic tebchaw;
Lwm qhov yog cov ntsiab lus ib puag ncig, uas yog, cov nquag nquag, cov uas ua rau muaj kev puas tsuaj. Nws yog pom tseeb tias volatilization thiab kev koom tes nyob rau hauv atmospheric photochemical cov tshuaj tiv thaiv yog ib qho tseem ceeb heev los ntawm ib puag ncig saib. Tsis txhob volatilize los yog tsis koom nyob rau hauv atmospheric photochemical tshuaj tiv thaiv tsis yog ib tug txaus ntshai.
2. UAS
Nyob rau hauv Suav teb, VOCs (volatile organic compounds) yog hais txog cov organic tebchaw nrog saturated vapor siab tshaj 70 Pa ntawm qhov kub thiab txias taw tes hauv qab 260 ℃ nyob rau hauv lub siab ib txwm, los yog tag nrho cov organic tebchaw nrog sib xws volatilizes ntawm vapor siab siab tshaj los yog sib npaug rau 10 Pa ntawm 20 ℃
Los ntawm qhov pom ntawm kev saib xyuas ib puag ncig, hais txog tag nrho cov uas tsis yog-methane hydrocarbons pom los ntawm hydrogen nplaim hluav taws xob ion ntes, feem ntau suav nrog alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketones thiab lwm yam organic compounds. Ntawm no yog tus yuam sij los piav qhia: VOC thiab VOCS yeej yog tib chav kawm ntawm cov khoom, uas yog, Volatile Organic Compounds abbreviation, vim Volatile Organic Compounds feem ntau muaj ntau tshaj li ib feem, yog li VOCS muaj tseeb dua.
3. TVOC
Cov kws tshawb fawb huab cua hauv tsev feem ntau xa mus rau tag nrho cov khoom siv hauv tsev Organic gaseous uas lawv coj mus kuaj thiab tshuaj xyuas raws li TVOC, uas yog thawj tsab ntawv ntawm peb lo lus Volatile Organic Compound, Cov vocs ntsuas tau sau npe hu ua Total Volatile Organic CompoundS (TVOC). TVOC yog ib qho ntawm peb hom kev ua qias tuaj cuam tshuam rau huab cua hauv tsev.
Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO, 1989) txhais tau hais tias tag nrho cov tsis muaj zog ntawm cov organic tebchaw (TVOC) raws li cov organic tebchaw uas tsis muaj zog nrog melting point hauv qab chav tsev kub thiab kub kub ntawm 50 thiab 260 ℃. Nws tuaj yeem evaporated hauv huab cua ntawm chav tsev kub. Nws yog tshuaj lom, khaus, carcinogenic thiab tsw tshwj xeeb, uas tuaj yeem cuam tshuam rau ntawm daim tawv nqaij thiab mucous daim nyias nyias thiab ua rau muaj kev puas tsuaj rau tib neeg lub cev.
Piv txwv li, nyob rau hauv qhov tseeb, kev sib raug zoo ntawm peb yuav qhia tau hais tias xws li inclusion relation:
