This study reports the analysis of nine bisphenols (BPA, BPAF, BPAP, BPB, BPC, BPE, BPF, BPS, BPZ) and related compounds (4-cumylphenol and dihydroxybenzophenone; DHBP) in honey and food simulant. After sample pre-concentration with Oasis HLB cartridges, analytes were silylated and analysed by GC-MS. The validated methods with LODs in sub ng/g were applied to 36 honey samples originating from various European and non-European countries and food simulant from migration testing of selected corresponding containers. Honey samples contained BPA, BPAF, BPE, BPF, BPS and BPZ in amounts up to 107 ng/g, 53.5 ng/g, 12.8 ng/g, 31.6 ng/g, 302 ng/g and 28.4 ng/g, respectively. Within migration testing, only BPA and BPAF were detected in food simulant up to 42.2 ng/ml and 19.8 ng/mL, respectively. In certain cases, the detected bisphenols in honey probably derive from a material other than the final packaging.

This study reports the occurrence of eight bisphenols (BPs): bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol B (BPB), bisphenol C (BPC), bisphenol E (BPE), bisphenol F (BPF), bisphenol S (BPS) and bisphenol Z (BPZ) in wastewaters (WWs). Sample preparation involved pre-concentration (SPE), followed by derivatization and analysis by gas chromatography–mass spectrometry. A validated method with limits of detection (LODs) at ng L- 1 range was applied to WWs collected at five Slovene wastewater treatment plants (WWTPs) and WW inflows from industrial, commercial and residential sources entering the sewerage systems of two catchments (Domžale-Kamnik (DK) and Ljubljana (LJ)). The presence of all BPs was confirmed in three inflows in DK and two inflows in the LJ catchments. High cumulative concentrations of all BPs were determined in WW from food processing facilities. A high detection frequency was observed in the WW from two textile cleaning companies. The analysis of WW from WWTPs revealed that only BPF (36.7 ng L- 1) and BPS (40.6 ng L- 1) were ) LODs in the influents, whereas other BPs were detected also in the effluents. Although BPs removal could not be directly compared between the WWTPs, bisphenols were in general highly removed (? 96.2%).

“46th International Symposium on High Performance Liquid Phase Separations and Related Techniques, HPLC 2017,” took place on Jeju Island, South Korea between 5th and 9th November 2017. The conference presented an opportunity for scientists to present their research work with colleagues, who shared their knowledge and experiences obtained during their career. Ester Heath presented reserach entitled “BPA and its alternatives in environment, food and biological fluids” as an invited lecture within IUPAC Session at HPLC 2017. The presentation included description of bisphenol alternative characteristics as well as their occurrence and cycling in different environmental and food compartments. In case of bisphenol A, also urinary BPA levels on Slovene national level and possible sources were proposed. Work also included presentation of developed and validated analytical methods for determining selected BPs in different matrices using solid phase extraction (SPE) procedure followed by GC and LC systems coupled to different mass spectrometry analysers. In addition, E. Heath presented this work as invited lectures: Ester Heath: Bisfenol A and its alternatives in relation to environment, food and health.
