“…Previous studies have demonstrated that the chemicals migrating into aqueous media include organic compounds and metals, phenols and phthalates, , as well as known estrogenic chemicals . Emerging research using nontarget analysis has expanded this spectrum greatly, especially with respect to NIAS. − However, concerns have been raised regarding the lack of hazard information for chemicals known to be present in FCMs, including plastics, as well as the challenge of unknown compounds migrating from such materials …”

Plastic products contain complex mixtures of extractable chemicals that can be toxic. However, humans and wildlife will only be exposed to plastic chemicals that are released under realistic conditions. Thus, we investigated the toxicological and chemical profiles leaching into water from 24 everyday plastic products covering eight polymer types. We performed migration experiments over 10 days at 40 °C and analyzed the migrates using four in vitro bioassays and nontarget high-resolution mass spectrometry (UPLC-QTOF-MS E ). All migrates induced baseline toxicity, 22 an oxidative stress response, 13 antiandrogenicity, and one estrogenicity. Overall, between 17 and 8681 relevant chemical features were present in the migrates. In other words, between 1 and 88% of the plastic chemicals associated with one product were migrating. Further, we tentatively identified ∼8% of all detected features implying that most plastic chemicals remain unknown. While low-density polyethylene, polyvinyl chloride, and polyurethane induced most toxicological endpoints, a generalization for other materials is not possible. Our results demonstrate that plastic products readily leach many more chemicals than previously known, some of which are toxic in vitro. This highlights that humans are exposed to many more plastic chemicals than currently considered in public health science and policies.

“…Based on significant variations in BPS levels in individual samples within the same food category collected from different stores, Cao et al 17 concluded that packaging was unlikely to be the source for BPS in meat. However, in a previous study from our research group 18 , BPS was detected in packaged fresh food (notably fish) purchased in Canada more frequently than in their non-packaged equivalents.…”

Food Thermal Labels are a Source of Dietary Exposure to Bisphenol S and Other Color Developers

To test the hypothesis that migration from the thermal labels on plastic film packaging is a major source of exposure to bisphenols and alternative color developers in food, we analyzed 140 packaging materials from packaged fresh food purchased in North America. No bisphenol A (BPA) was detected in either the packaging samples or thermal labels. However, significant amounts of bisphenol S (BPS) and alternative color developers (up to 214 μg/cm2) were present in thermal labels; their relative occurrence varied among stores. In a controlled experiment, we wrapped fish in film with a thermal label for five days at 4℃. The fish in contact with the label contained BPS (≤ 1140 ng/g wet weight [ww]), 4-hydroxyphenyl 4-isoprooxyphenylsulfone (D-8) (≤ 230 ng/g ww), bis(2-chloroethyl)ether-4,400-dihydroxydiphenyl sulfone monomer (D-90) (≤ 3.41 ng/g ww), and Pergafast-201 (≤ 1.87 ng/g ww). This study provides evidence, for the first time, that BPS and alternative thermal label color developers migrate from packaging materials into food. Further, BPS migration significantly exceeded the European Union Specific Migration Limit (50 ng/g ww), suggesting that further risk assessment studies are warranted.

“…Plastic additives can also transfer to beverages from plastic packages ( Gómez Ramos et al, 2019 , Pelegrín et al, 2020 ). Numerous literature data report the presence of toxic chemicals in plastic food contact products ( Ayamba et al, 2018 , Qian et al, 2018 ) and beverages ( Tian et al, 2020 ). Unfortunately, pregnant women ( Zeman et al, 2013 ) and newborns ( Socas-Rodríguez et al, 2018 ) are also exposed to plastics additives, which may pose a great danger.…”
