1. I-VOC
Izinto ze-VOC zibhekisa kwizinto eziphilayo eziguquguqukayo. I-VOC imele iikhompawundi ze-Volatile Organic S. I-VOC ngokubanzi ngumyalelo wezinto eziphilayo ezivelisayo; Kodwa inkcazo yokhuseleko lokusingqongileyo ibhekisa kuhlobo lweekhompawundi ze-volatile organic ezisebenzayo, ezinokubangela ingozi.
Enyanisweni, ii-VOC zingahlulwahlulwa zibe ziindidi ezimbini:
Enye yinkcazo ngokubanzi ye-VOC, kuphela ukuba yintoni na iikhompawundi ze-organic eziguquguqukayo okanye phantsi kweziphi iimeko apho iikhompawundi ze-organic eziguquguqukayo;
Enye yinkcazo yokusingqongileyo, oko kukuthi, ezo zisebenzayo, ezo zibangela ingozi. Kucacile ukuba ukuguquguquka kunye nokubamba inxaxheba kwiimpendulo ze-photochemical emoyeni kubaluleke kakhulu ngokwembono yokusingqongileyo. Ukungaguquguquki okanye ungathathi nxaxheba kwimpendulo ye-photochemical emoyeni akuyongozi.
2. I-VOCS
ETshayina, ii-VOC (iikhompawundi ze-organic eziguquguqukayo) zibhekisa kwiikhompawundi ze-organic ezinoxinzelelo lomphunga olugcweleyo olungaphezulu kwe-70 Pa kubushushu obuqhelekileyo kunye neqondo lokubila elingaphantsi kwe-260℃ phantsi koxinzelelo oluqhelekileyo, okanye zonke iikhompawundi ze-organic ezine-volatilizes ezifanayo kuxinzelelo lomphunga olungaphezulu okanye olulingana ne-10 Pa kwi-20℃
Ngokwembono yokujonga okusingqongileyo, ibhekisa kwiihydrocarbons ezingezizo i-methane ezifunyenwe yi-hydrogen flame ion detector, ikakhulu kuquka ii-alkanes, ii-aromatics, ii-alkenes, ii-halohydrocarbons, ii-esters, ii-aldehydes, ii-ketones kunye nezinye iikhompawundi ze-organic. Nantsi isitshixo sokuchaza: Ii-VOC kunye nee-VOCS ngokwenene ziluhlobo olufanayo lwezinto, oko kukuthi, isifinyezo seeKhompawundi ze-Volatile Organic, kuba iiKhompawundi ze-Volatile Organic ngokubanzi zingaphezulu kwesinye, ngoko ke ii-VOCS zichaneke ngakumbi.
3. I-TVOC
Abaphandi bomgangatho womoya wangaphakathi badla ngokubhekisa kuzo zonke izinto zegesi ze-Organic zangaphakathi abazithatha njenge-TVOC, emele unobumba wokuqala wamagama amathathu athi Volatile Organic Compound, la mazwi alinganiswayo aziwa ngokuba yiTotal Volatile Organic CompoundS (TVOC). I-TVOC yenye yeentlobo ezintathu zongcoliseko oluchaphazela umgangatho womoya wangaphakathi.
I-World Health Organisation (WHO,1989) ichaze ii-total volatile organic compounds (TVOC) njengee-volatile organic compounds ezine-melting point engaphantsi kobushushu begumbi kunye ne-boliting point ephakathi kwama-50 nama-260℃. Ingatshintshwa emoyeni xa ishushu. Inetyhefu, iyacaphukisa, ibangela umhlaza kwaye inevumba elikhethekileyo, elinokuchaphazela ulusu kunye ne-mucous membrane kwaye ibangele umonakalo omkhulu emzimbeni womntu.
Ukushwankathela, eneneni, ubudlelwane phakathi kwaba bathathu bunokubonakaliswa njengobudlelwane bokubandakanywa:
