Bisphenol A is a monomer used primarily in the production of polycarbonate   plastics and epoxy resins. Polycarbonate plastic is used in a wide variety   of digital media products, electrical and electronic equipment, sport safety   equipment, reusable food and drink containers, etc. Epoxy resins are used in   engineering applications, paints and adhesives and also in a variety of   protective coatings in metal cans for foods, bottle tops and water supply   pipes. The content of BPA was evaluated in 16 samples (6 baby bottles and 10   drinking containers - can) collected during 2018/2019, of which three baby   bottles and 8 cans were collected in 2018, while three baby bottles and 2   cans in 2019. A simple HPLC-FLD analytical method was validated for the   quantitation of BPA from baby feeding bottles and cans. The separation was   performed on a C18 column. Good linearity was obtained over the   concentration range of 0.3-6.0 ?g/mL with the regression coefficient (R2) of   0.9998. The limit of detection (LOD) and limit of quantification (LOQ) were   0.01 and 0.03 ?g/mL, respectively. The repeatability of the method (%RSD)   was between 4 and 6%, while the recovery ranged from 104.3 to 109.7%. The   extraction of BPA was done in accordance with SRPS EN 13130-1:2008. The   methods were applied to determine BPA release from baby bottles, performing   repeated procedures according to EU and national regulations (SRPS CEN/TS   13130-13 (2008)). The conformity was evaluated according to National and EU   requirements. The results show that Bisphenol-A was not detectable in any of   the analysed samples.
