1. I-VOC
Izinto ze-VOC zibhekisela ezintweni eziphilayo eziguquguqukayo.I-VOC imele i-Volatile Organic compoundS.I-VOC ngomqondo ojwayelekile iwumyalo wezinto eziphilayo ezikhiqizayo;Kodwa incazelo yokuvikelwa kwemvelo ibhekisela ohlotsheni lwezinhlanganisela eziphilayo eziguquguqukayo ezisebenzayo, ezingaveza ukulimala.
Eqinisweni, ama-VOC angahlukaniswa abe izigaba ezimbili:
Enye incazelo evamile ye-VOC, kuphela yiziphi izinhlanganisela eziphilayo eziguquguqukayo noma ngaphansi kwaziphi izimo izinhlanganisela eziphilayo eziguquguqukayo;
Enye incazelo yezemvelo, okungukuthi, ezisebenzayo, lezo ezidala umonakalo.Kusobala ukuthi ukuguquguquka nokubamba iqhaza ekuphenduleni kwe-photochemical emkhathini kubaluleke kakhulu ngokombono wemvelo.Ungaguquguquki noma ungabambi iqhaza ku-atmospheric photochemical reaction akusho ingozi.
2.VOCS
E-China, ama-VOCs (izinto eziphilayo ezishintshashintshayo) asho izinhlanganisela eziphilayo ezinomfutho womhwamuko osuthisiwe omkhulu kuno-70 Pa ezingeni lokushisa elivamile nendawo yokubila engaphansi kuka-260 ℃ ngaphansi kwengcindezi evamile, noma zonke izinhlanganisela eziphilayo ezinokuwohloka okuhambisanayo ku-vapor pressure enkulu noma elingana no-10. Pa ku-20 ℃
Ngokombono wokuqapha indawo ezungezile, kubhekiselwa kuwo wonke ama-hydrocarbon angewona ama-methane atholwe umtshina we-ion ion we-hydrogen flame, ikakhulukazi ohlanganisa ama-alkanes, ama-aromatics, ama-alkenes, ama-halohydrocarbon, ama-esters, ama-aldehydes, ama-ketone nezinye izinhlanganisela eziphilayo.Nasi isihluthulelo sokuchaza: I-VOC ne-VOCS empeleni ziyisigaba esifanayo sezinto, okungukuthi, isifinyezo se-Volatile Organic Compounds, ngoba i-Volatile Organic Compounds ngokuvamile ingaphezu kwengxenye eyodwa, ngakho i-VOCS inembe kakhulu.
3.TVOC
Abacwaningi bekhwalithi yomoya wasendlini ngokuvamile babhekisela kuzo zonke izinto ze-Organic gaseous zasendlini abazisampulayo futhi bazihlaziye njenge-TVOC, emele uhlamvu lokuqala lwamagama amathathu I-Volatile Organic Compound, Amagama alinganiswayo aziwa ngokuhlanganyela ngokuthi I-Total Volatile Organic CompoundS (TVOC).I-TVOC ingenye yezinhlobo ezintathu zokungcola okuthinta izinga lomoya wasendlini.
I-World Health Organization (WHO, 1989) ichaze i-total volatile organic compounds (TVOC) njengezinhlanganisela eziphilayo eziguquguqukayo ezinephuzu elincibilikayo elingaphansi kwezinga lokushisa kanye nendawo yokubilisa phakathi kuka-50 no-260℃.Ingahwamuka emoyeni ekamelweni lokushisa.Inobuthi, iyacasula, i-carcinogenic kanye nephunga elikhethekile, elingathinta isikhumba kanye nolwelwesi lwamafinyila futhi libangele ukulimala okukhulu emzimbeni womuntu.
Ukufingqa, empeleni, ubudlelwano phakathi kwalaba abathathu bungavezwa njengokuhlobana kokufakwayo:
