Trace Analysis of Environmental Endocrine Disrupting Contaminant Bisphenol A in Canned, Glass and Polyethylene Terephthalate Plastic Carbonated Beverages of Diverse Flavors and Origin

Bisphenol A (BPA) is a hazardous contaminant demonstrating endocrine disrupting properties, and assumed to be involved in the pathogenesis of various cancer diseases for instance prostate, lung and breast cancer. The objective of the present study was to estimate the BPA amounts in carbonated beverages from the Saudi Arabian market for the first time using an authenticated technique based on solid-phase extraction and ultra-performance liquid chromatography-tandem mass spectrometry. A total of thirty-four carbonated beverages of different flavors, origin and packaging materials were studied. The beverage production periods were from February 2018 to July 2018 containing volume (250-1000 mL), packaging materials were of canned, glass and polyethylene terephthalate (PET) plastic. BPA amounts in canned (0.64-11.41 µg/L), glass bottled (1.92-29.56 µg/L) and PET plastic bottled (0.37-21.83 µg/L) were obtained with recovery (97.64-99.96%). Relatively, glass bottled has offered higher amounts of BPA compared to PET plastic bottled and canned samples. The unforeseen presence of BPA especially in glass bottled emphasizes the ubiquity of such compound beside the food fabrication chain, far off to the food packaging materials. Thus, a further knowledge on BPA amounts in glass bottled samples, in addition to threat assessment studies, is essential to defend human health.
