20.500.12556/RUL-184246 Izločanje bisfenolov iz športnih oblačil Leaching of Bisphenols from Athletic Apparel Endokrini motilci so skupina kemijskih snovi, ki lahko že pri nizkih koncentracijah vplivajo na delovanje hormonskega sistema in predstavljajo tveganje za okolje in zdravje ljudi. Med njimi so posebej pomembni bisfenoli, ki se zaradi široke industrijske uporabe pojavljajo v številnih potrošniških izdelkih. Namen diplomskega dela je bil ugotoviti, ali se bisfenoli iz športnih oblačil izločajo v umetni znoj, ter kako na njihovo prisotnost vpliva število pralnih ciklov. Analizo sem izvedel z uporabo ekstrakcije na trdni fazi (SPE) ter tekočinske kromatografije v povezavi z masno spektrometrijo. Rezultati so pokazali, da se iz preučevanega športnega oblačila v umetni znoj izločajo BPA, BPF in BPS, pri čemer je bil BPS prisoten v najvišjih koncentracijah. Z naraščajočim številom pranj se je koncentracija vseh analiziranih bisfenolov izrazito zmanjševala. Ugotovitve kažejo, da lahko športni tekstil predstavlja vir izpostavljenosti bisfenolom, vendar se ta s pranjem bistveno zmanjša. Delo prispeva k boljšemu razumevanju vloge tekstila kot vira endokrinih motilcev in poudarja pomen nadaljnjih raziskav na tem področju. Endocrine disruptors are a group of chemical substances that can affect the functioning of the hormonal system even at low concentrations and pose a risk to human health and the environment. Among them, bisphenols are of particular importance, as they are widely used in industry and therefore occur in numerous consumer products.The aim of this bachelor’s thesis was to determine whether bisphenols are released from sports clothing into artificial sweat and how the number of washing cycles affects their presence. The analysis was performed using solid-phase extraction (SPE) and liquid chromatography coupled with mass spectrometry.The results showed that BPA, BPF, and BPS are released from the examined sports garment into artificial sweat, with BPS being present at the highest concentrations. With an increasing number of washing cycles, the concentrations of all analyzed bisphenols decreased significantly. The findings indicate that sports textiles can represent a source of exposure to bisphenols; however, this exposure is substantially reduced by washing. This work contributes to a better understanding of the role of textiles as a source of endocrine disruptors and highlights the importance of further research in this field. bisfenoli endokrini motilci športna oblačila tekočinska kromatografija bisphenols endocrine disruptors sportswear liquid chromatography true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-07-02 12:30:29 2026-07-02 12:30:40 2026-07-03 04:23:35 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 25684 But_Lenart_-_Izlocanje_bisfenolov_iz_sportnih_oblacil.pdf But_Lenart_-_Izlocanje_bisfenolov_iz_sportnih_oblacil.pdf 1 C9239EAC388D06FB828EC0E55A8BD103 a0c5684e9543882147aa79906040eeb2237abb7d1b51b057f1d28a8ef67c7d17 006f392a-7601-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=236864 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
