1. VOC
Izinto ze-VOC zibhekisa kwizinto eziphilayo eziguqukayo.I-VOC imele iVolatile Organic compounds.I-VOC ngokwengqiqo jikelele ngumyalelo we-generative organic matter;Kodwa inkcazo yokukhuselwa kwendalo ibhekiselele kuhlobo lwee-organic compounds eziguquguqukayo ezisebenzayo, ezinokuvelisa umonakalo.
Enyanisweni, ii-VOCs zinokwahlulwa zibe ngamacandelo amabini:
Enye inkcazo jikelele ye-VOC, kuphela yintoni i-volatile organic compounds okanye phantsi kweziphi iimeko eziguquguqukayo ze-organic compounds;
Enye inkcazo yokusingqongileyo, oko kukuthi, ezisebenzayo, ezo zibangela ingozi.Kucacile ukuba i-volatilization kunye nokuthatha inxaxheba kwi-atmospheric photochemical reactions kubaluleke kakhulu ukusuka kwindawo yokujonga indawo.Musa ukuguquguquka okanye ungathathi nxaxheba kwi-atmospheric photochemical reaction ayibi yingozi.
2.VOCS
E-China, ii-VOCs (i-volatile organic compounds) zibhekiselele kwiikhompawundi zezinto eziphilayo ezinoxinzelelo lomphunga ozeleyo ngaphezu kwe-70 Pa kwiqondo lobushushu eliqhelekileyo kunye neqondo lokubila elingaphantsi kwe-260℃ phantsi koxinzelelo oluqhelekileyo, okanye zonke iikhompawundi zezinto eziphilayo ezinokuguquguquka okuhambelanayo kuxinzelelo lomphunga olukhulu okanye olulingana ne-10. Pa ku 20℃
Ngokombono wokubekwa kweliso kokusingqongileyo, ibhekisa kwitotali ye-non-methane hydrocarbons efunyenwe yi-hydrogen flame ion detector, ingakumbi i-alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketones kunye nezinye iikhompawundi eziphilayo.Nali isitshixo sokuchaza: I-VOC kunye ne-VOCS ziludidi olufanayo lwezinto, oko kukuthi, i-Volatile Organic Compounds isifinyezo, kuba i-Volatile Organic Compounds ngokubanzi ngaphezu kwecandelo elinye, ngoko i-VOCS ichaneke ngakumbi.
3.TVOC
Abaphandi bomgangatho womoya wangaphakathi badla ngokubhekisa kuzo zonke izinto ezingaphakathi kwirhasi ye-Organic abayisampulu kwaye bayihlalutye njenge-TVOC, emele unobumba wokuqala wamagama amathathu iVolatile Organic Compound, Iizwi ezilinganisiweyo zaziwa ngokudibeneyo njengeTotal Volatile Organic CompoundS (TVOC).I-TVOC yenye yeentlobo ezintathu zongcoliseko oluchaphazela umgangatho womoya wangaphakathi.
Umbutho wezeMpilo weHlabathi (i-WHO,1989) uchaze iikhompawundi eziguquguqukayo ezipheleleyo ze-organic (TVOC) njengeekhompawundi eziguquguqukayo zezinto eziphilayo ezinendawo yokunyibilika engaphantsi kobushushu begumbi kunye nendawo yokubila phakathi kwe-50 kunye ne-260℃.Inokuthi ibe ngumphunga emoyeni kwiqondo lobushushu begumbi.Inetyhefu, iyacaphukisa, i-carcinogenic kunye nevumba elikhethekileyo, elinokuthi lichaphazele ulusu kunye ne-mucous membrane kwaye libangele umonakalo omkhulu kumzimba womntu.
Ukushwankathela, enyanisweni, ubudlelwane phakathi kwaba bathathu bunokubonakaliswa njengonxulumano olubandakanyayo:
