1. VOC
VOC zvinhu zvinoreva volatile organic zvinhu. VOC inomirira Volatile Organic compounds. VOC mupfungwa yakajairika murairo wezvinogadzirwa organic zvinhu; Asi tsananguro yekuchengetedzwa kwezvakatipoteredza inoreva rudzi rwekuvhuvhuta organic komisheni inoshanda, inogona kuburitsa kukuvadza.
Muchokwadi, maVOC anogona kukamurwa kuita mapoka maviri:
Imwe ndiyo tsananguro yakajairika yeVOC, chete chii chinonzi volatile organic compounds kana pasi pemamiriro api ari kutenderera organic komisheni;
Imwe ndiyo tsanangudzo yezvakatipoteredza, kureva, iyo inoshanda, iyo inokonzera kukuvadza. Zviri pachena kuti volatilization uye kutora chikamu mumhepo yemhepo photochemical reactions kwakakosha zvakanyanya kubva kune yezvakatipoteredza maonero. Usatenderere kana kusatora chikamu mumhepo yepamhepo photochemical reaction haiite njodzi.
2.VOCS
KuChina, maVOCs (volatile organic compounds) anoreva maorganic compounds ane saturated mhute pressure inodarika 70 Pa patembiricha yakajairwa nenzvimbo yekubikira iri pasi pe260 ℃ pasi pekumanikidzwa kwakajairwa, kana ese organic compounds ane anowirirana anovhurika pahutsi hwehutsi hunodarika kana kuenzana negumi. Pa pa20 ℃
Kubva pakuona kwekutarisa kwezvakatipoteredza, inoreva iyo yakazara isiri-methane hydrocarbons yakaonekwa nehydrogen flame ion detector, kunyanya inosanganisira alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketones uye mamwe organic compounds. Heino kiyi yekutsanangura: VOC neVOCS ndizvo chaizvo kirasi imwechete yezvinhu, kureva, Volatile Organic Compounds pfupiso, nekuti Volatile Organic Compounds mune zvakajairika zvinopfuura chikamu chimwe, saka VOCS yakanyatsojeka.
3.TVOC
Vatsvagiri vemhando yemhepo yemukati vanowanzo tarisa kune ese emukati Organic gaseous zvinhu zvavanoyedza uye kuongorora seTVOC, inomiririra bhii rekutanga remazwi matatu Volatile Organic Compound, Iwo manzwi akayerwa anozivikanwa pamwe chete seTotal Volatile Organic CompoundS (TVOC). TVOC ndeimwe yemhando nhatu dzekusvibiswa kunokanganisa mukati memhepo mhando.
World Health Organisation (WHO,1989) yakatsanangura yakazara volatile organic compounds (TVOC) seanoshanduka organic komisheni ine nzvimbo yekunyungudika iri pasi pekamuri tembiricha uye nzvimbo yekuvira iri pakati pe50 ne260 ℃. Inogona kunyungudutswa mumhepo pane tembiricha yekamuri. Iyo ine muchetura, inogumbura, carcinogenic uye yakakosha kunhuhwirira, iyo inogona kukanganisa ganda uye mucous membrane uye kukonzera kukuvadza kwakanyanya kumuviri wemunhu.
Kupfupisa, kutaura zvazviri, hukama pakati pevatatu hunogona kuratidzwa sehukama hwekubatanidza:
