Bakeng sa VOCs

Ho karoloana le libopi tse kauu 900 tseo e-bileng li ntse li ntse li baloetsoe ka hare, ho bapala hore e-be e-ne ea liphaephele tse 350 tsa karoloana tse susumetsang (VOCs), tse emetseng maemo a tlase ho ppb e le 'ngoe. Ho fetisisa ho likaroloana tsena tse 20 li na le thuso ea tlaea tšebetso ea limolikyula kapa tlaea phetoho. Empa haeba sebele sa karoloana ke sene, phethahatso ea VOCs e arabela hore e hlolohe ho TVOC (Total Volatile Organic Compounds). Tlhokomeliso e kopaneng ea liphaephele tse ngata tseo li leng teng ka hare ha ntlo ha e-na moeli.

Lihlopha tse holim'a TVOCs tse tloaelehileng di kenyelletsa alkanes/cycloalkanes, aromatic hydrocarbons, alkenes, alcohols, phenols, ketones, le terpenes. Tlhahiso e tloaelehileng e ipiletseng batho ke phoso ea matla, mahlolo, le molomo, e bitsang litlhahiso tse kang:

l Lipotso tsa litholoana, tšoako, ho pheta-pheta ha lintho, le ho fofa;

l Tšoako, lipotso, litlhare, phahlo ea nasopharynx, hammoho le ho hlapola, ho qetella, le phapano ea buka;

l Ho phetsahala ha bophelo le boloko;

l Tšoako ea leholimo, ho phata, ho sena, le erythema.

l Mekhoa e meng ea tlaleho ea VOC e kenyelletsa chromatography ea ntle-nyenyee ea mohloli oa ionization (GC-FID), spektroskopi ea Fourier-transform infrared (FTIR), le tekong ea photoionization (PID). Khamphani ya rona e rekomenda haholo mefuta ea polomere ea boemo e itseng ea VOC ea Germany’s SEC, e felang mefuta e mengata ea thuso e kenyelletsoang 0–200 ppm, 0–1000 ppm, 0–2000 ppm, le 0–5000 ppm. Lisebe tsena li bonolo ho sebetsa, li sa lefube, le li sebelisoa ka botlalo libakeng tse kang ho printa le ho ngola, hammoho le ho monitora boemo ba hlahiso.
