“…The IR spectrum of the can coating (Fig. ) showed that there were some characteristic peaks of epoxyphenolic resin, including those at 1606, 1508, 1237 and 828 cm −1 . BPA and BADGE were the only bisphenols found, at average levels of 83.77 ± 4.84 and 700.52 ± 9.51 µg · dm −2 respectively, which verified that the can coating contained bisphenol components.…”

“…Although the polarity of SimD is lower than that of SimC, which could cause more migration of BADGE with strong lipophilic character, oxidation reactions in SimD during heating at 121 °C for 30 min could lead to some degradation of bisphenols (especially BPA) . In SimB, BADGE could hydrolyze because of the presence of H + , and the hydrolysis reaction would become more intense during heating at 121 °C for 30 min . Meanwhile, this situation would occur in SimA only to a slight degree.…”

“…When waste plastics produced form BPA are buried in a landfill, a hydrolytic or leaching process may occur to release BPA to the leachate. [14][15][16] Recently the bisphenol derivatives such as bisphenol B (BPB), 17 bisphenol C (BPC), [18][19][20][21] bisphenol E (BPE), 22,23 bisphenol F (BPF), [24][25][26] bisphenol O (BPO), 27 bisphenol S (BPS), [28][29][30] bisphenol T (BPT), 31,32 and bisphenol Z (BPZ) 33,34 shown in Figure 1 have come into wide use for synthesis of specialized epoxy and polycarbonate resins with more high-performance compared with ordinary ones. Although these bisphenol derivatives have two phenol groups in common, the chemical structure between phenol groups is different.…”

In this study, the availability of chitosan was systematically investigated for removal of bisphenol A (BPA, 2,2-bis(hydroxyphenyl)propane) through the tyrosinase-catalyzed quinone oxidation and subsequent quinone adsorption on chitosan beads. In particular, the process parameters, such as the hydrogen peroxide (H 2 O 2 )-to-BPA ratio, pH value, temperature, and tyrosinase dose, were discussed in detail for the enzymatic quinone oxidation. Tyrosinase-catalyzed quinone oxidation of BPA was effectively enhanced by adding H 2 O 2 and the optimum conditions for BPA at 0.3 mM were determined to be pH 7.0 and 40 C in the presence of H 2 O 2 at 0.3 mM ([H 2 O 2 ]/[BPA] ¼ 1.0). Removal of BPA from aqueous solutions was accomplished by adsorption of enzymatically generated quinone derivatives on chitosan beads. The use of chitosan in the form of beads was found to be more effective because heterogeneous removal of BPA with chitosan beads was much faster than homogeneous removal of BPA with chitosan solutions, and the removal efficiency was enhanced by increasing the amount of chitosan beads dispersed in the BPA solutions and BPA was completely removed by quinone adsorption in the presence of chitosan beads more than 0.10 cm 3 /cm 3 . In addition, a variety of bisphenol derivatives were completely or effectively removed by the procedure constructed in this study, although the enzyme dose or the amount of chitosan beads was further increased as necessary for some of the bisphenol derivatives used.

“…They concern the leeching of bisphenols into foods from food storage containers. 38 Another article concerned the leeching of bisphenol from wine corks. 39 The earlier study claims that leeching is minimal, but they do not consider the hazards of low dose effects; perhaps due to the very early nature of this study.…”

Bisphenol compounds are a class of chemical epoxy resins that are found throughout the world in food packaging, thermal paper products, dental materials, and more. These compounds were deemed to be safe until recently, when some studies noticed adverse effects at very low doses, due to the fact that bisphenol acts as an endocrine disruptor. Over the last ten years, studies have been performed to detect bisphenols (especially BPA) in serum and blood samples throughout the world. Essentially, the majority of the earth's population seems to have significantly measurable levels of bisphenol in their blood plasma or urine. However, the majority of the population is unaware that a potential danger may exist. The purpose of this mini-review is to report upon the state of bisphenol research in the lesser developed member-states of the European Union and to increase awareness of the exposure level and possible adverse health effects of this endocrine disruptor. The results show that only three of the most newly admitted members of the European Union have published research concerning the health effects and/or environmental exposure of EU citizens to bisphenol compounds. Those countries were Slovenia, Poland and the Czech Republic. The rest of the surveyed member-states had little or no published research in relation to bisphenol compounds. Furthermore, even the three nations referred to above still lagged far behind the more advanced EU member-states. The lack of research could translate into a lack of awareness amongst the citizenry of nearly half of the EU, and may be unnecessarily putting those EU citizens at an increased risk of exposure.
