20.500.12556/RUL-188182 Lahkohlapne organske spojine v e-cigaretah magistrska naloga Volatile organic compounds in e-cigarettes master thesis Uvod: Uporaba e-cigaret čedalje bolj narašča, predvsem po njih posegajo ranljivejše skupine, kot so mladi in nosečnice. Velja prepričanje, da je uporaba e-cigaret manj škodljiva od uporabe klasičnih cigaret, vendar se vse bolj kažejo tudi škodljivi učinki e-cigaret. E-tekočina je običajno sestavljena iz topila, arom in pogosto nikotina v različnih odmerkih. Vsebuje tudi spojine, ki so označene kot varne za zaužitje (GRAS), vendar nimajo podatkov o varnosti pri vdihavanju, kar predstavlja tveganje za zdravje. Namen: Želeli smo ugotoviti in identificirati, katere spojine vsebujejo izbrane e-cigarete in v kakšnih koncentracijah, oceniti morebitna zdravstvena tveganja, povezana z njihovim vdihavanjem, ter preučiti neskladja med deklarirano in dejansko izmerjeno kemično sestavo. Metode dela: Uporabljena je bila deskriptivna metoda pregleda literature. Analizirali in primerjali smo 9 različnih vzorcev e-cigaret z analitsko metodo spojin s plinsko kromatografijo v povezavi z masno spektrometrijo. Zaključek: Danes je malo znanega o dolgoročnih učinkih uporabe e-cigaret, saj so na trgu manj kot 20 let. Posledično spojine v e-cigaretah še niso dobro raziskane in ne poznamo njihovih vplivov na zdravje ljudi, zato ne moremo trditi, da so varnejše ali škodljivejše od klasičnih cigaret. Učinki ter vsa tveganja, ki jih e-cigarete predstavljajo, se bodo začeli kazati šele v prihodnosti. Introduction: The use of e-cigarettes is continuously increasing, and they are most commonly used by vulnerable groups such as young people and pregnant women. There is a widespread belief that e-cigarettes are less harmful than conventional cigarettes; however, the harmful effects of e-cigarettes are becoming increasingly evident. E-liquid typically consists of a solvent, flavourings, and often nicotine in varying doses. It also contains compounds that are classified as Generally Recognized as Safe (GRAS) for ingestion, but there are no safety data regarding inhalation, which represents a potential risk. Aim: The aim was to identify which compounds are present in selected e-cigarettes, determine their concentrations, assess the potential health risks associated with their inhalation, and examine discrepancies between the declared and the actually measured chemical composition. Methods: A descriptive literature review method was used. We analysed and compared nine different e-cigarette samples using the analytical method of gas chromatography coupled with mass spectrometry. Conclusion: Currently, little is known about the long-term effects of e-cigarette use, as they have been on the market for less than 20 years. Consequently, the compounds in e-cigarettes have not been sufficiently studied, and their effects on human health are not fully understood. Therefore, it cannot be concluded that they are safer or more harmful than conventional cigarettes. The effects and risks associated with e-cigarettes will likely become more evident in the future. magistrska dela sanitarno inženirstvo e-cigarete arome plinska kromatografija GRAS toksikološki učinki master's theses sanitary engineering e-cigarettes flavourings gas chromatography GRAS toxicological effects true false false [T.
