ABSTRACT
A precise and accurate GC-MS/MS method with ngâ¯L-1 LLOQs, acceptable recovery (78-107%) and estimated uncertainty (Uâ¯>â¯20%, except at LLOQ) was developed following the Eurachem guidelines. We established the migration and stability of twelve bisphenols in two food simulants (C 20% ethanol, and B 3% acetic acid) from beverage cans (nâ¯=â¯16) and reusable metal and plastic sports bottles (nâ¯=â¯51). Bisphenols were stable in dried (eight weeks, -20⯰C) and derivatised extracts (seven days, 21⯰C). Cans leached BPA (<5865â¯ngâ¯L-1), three BPF isomers (8.2-1286â¯ngâ¯L-1) and BPAP (1.6â¯ngâ¯L-1), while bottles leached BPA (<222â¯ngâ¯L-1) and BPF, BPE, BPB and BPZ (1.1-4.6â¯ngâ¯L-1). Simulant C was more aggressive than simulant B, and concentrations of bisphenols decreased with consecutive exposure to simulants. Levels of BPA migrating from cans did not exceed the specific migration limits.
