1. VOC
ʻO nā mea VOC e pili ana i nā mea kūlohelohe volatile. ʻO VOC ke kū nei no ka Volatile Organic compoundS. ʻO VOC ma ke ʻano laulā ke kauoha o nā mea kūlohelohe generative; Akā ʻo ka wehewehe ʻana o ka palekana o ke kaiapuni e pili ana i kahi ʻano o nā mea kūlohelohe volatile e hana nei, hiki ke hana i ka pōʻino.
ʻO kaʻoiaʻiʻo, hiki ke hoʻokaʻawale ʻia nā VOC i ʻelua mau māhele:
ʻO kekahi ka wehewehe laulā o VOC, ʻo ia wale nō nā hui organik volatile a i ʻole ma lalo o nā kūlana he mau hui organik volatile;
ʻO kekahi ka wehewehe ʻana i ke kaiapuni, ʻo ia hoʻi, nā mea hana, nā mea e hōʻeha ai. He mea maopopo he mea nui loa ka volatilization a me ke komo ʻana i nā hopena photochemical lewa mai kahi manaʻo kaiapuni. Mai volatilize a i ʻole ʻaʻole komo i ka hopena photochemical lewa ʻaʻole ia he mea weliweli.
2.VOCS
Ma Kina, ʻo nā VOC (volatile organic compounds) e pili ana i nā hui organik me ke kaomi mahu saturated ʻoi aku ma mua o 70 Pa ma ka mahana maʻamau a me ka paila ma lalo o 260 ℃ ma lalo o ke kaomi maʻamau, a i ʻole nā hui organik āpau me nā volatilizes like ma ke kaomi mahu ʻoi aku ma mua o 10 Pa ma 20 ℃.
Mai ka manaʻo o ka nānā ʻana i ke kaiapuni, pili ia i ka huina o nā hydrocarbons non-methane i ʻike ʻia e ka mea ʻike ion lapalapa hydrogen, ʻo ia hoʻi nā alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketones a me nā hui organik ʻē aʻe. Eia ke kī e wehewehe ai: ʻO VOC a me VOCS ka papa like o nā mea, ʻo ia hoʻi, ʻo Volatile Organic Compounds acronym, no ka mea ʻoi aku ma mua o hoʻokahi ʻāpana o nā Volatile Organic Compounds, no laila ʻoi aku ka pololei o VOCS.
3.TVOC
ʻO ka mea maʻamau, kapa nā kānaka noiʻi no ka maikaʻi o ka ea o loko i nā mea kinoea organik a pau a lākou e laʻana ai a kālailai ai ʻo TVOC, ʻo ia hoʻi ka leka mua o nā huaʻōlelo ʻekolu ʻo Volatile Organic Compound. ʻO nā vocs i ana ʻia ua kapa ʻia ʻo Total Volatile Organic CompoundS (TVOC). ʻO TVOC kekahi o nā ʻano haumia ʻekolu e hoʻopilikia ana i ka maikaʻi o ka ea o loko.
Ua wehewehe ka World Health Organization (WHO, 1989) i nā hui organik volatile holoʻokoʻa (TVOC) ma ke ʻano he mau hui organik volatile me kahi heheʻe ma lalo o ka mahana o ka lumi a me kahi paila ma waena o 50 a me 260 ℃. Hiki ke hoʻoheheʻe ʻia i ka lewa i ka mahana o ka lumi. He mea ʻawahia, hoʻonāukiuki, carcinogenic a he ʻala kūikawā, hiki ke hoʻopilikia i ka ʻili a me ka membrane mucous a hōʻeha nui i ke kino o ke kanaka.
I ka hōʻuluʻulu ʻana, ʻo ka ʻoiaʻiʻo, hiki ke hōʻike ʻia ka pilina ma waena o nā mea ʻekolu ma ke ʻano he pilina hoʻokomo:
