“…Phthalate-based plasticizers have been also widely added to improve the flexibility, processability, and durability of PVC [ 39 ]. Both organotin compounds and plasticizers tend to migrate to the surface of the polymer because they are usually not chemically bonded to the polymer chain [ 40 , 41 ]. Release of the plasticizer is one of the main causes of the deterioration of plasticized PVC, resulting in mass loss, embrittlement of the bulk, and the appearance of sticky exudates on the surface, which could appear as white deposits on the torso of Barbie #4 due to the presence of organotin compounds.…”

Mattel’s Barbie dolls are the most famous and iconic dolls since 1959. Today, they are being collected by individuals and often conserved in museum environments due to their cultural and historical significance reflecting everyday life and historical events. However, just like most museum objects made of plastics, both historical and more recent Barbies show evident degradation phenomena. Firstly, Barbies were made of plasticized polyvinyl chloride (PVC), affected by the migration of additives—mostly the plasticizers—from the bulk phase to the outermost layer, appearing as a tacky and glossy exudate. Over the years, Barbies’ polymeric constituents were replaced with more stable ones, whose additives migration is limited compared to PVC, even though still occurring. Multispectral photography in visible (VIS) and ultraviolet (UV) light, microscopical observations in VIS and UV light, and Fourier Transform Infrared spectroscopy in the Attenuated Total Reflectance mode (FT-IR ATR) were performed to characterize the constituent materials of 15 Barbies produced between 1959 and 1976, bridging the information gap on their processing over the years. The micro-invasive multi-analytical approach also allowed for the characterization of the degradation products, permitting the reference of the exudated compound to the specific bulk polymer.

“…Surface enhanced Raman scattering (SERS) can realize quick detection by enhancement of the Raman scattering intensity of molecules in the presence of nanostructured metallic surface. SERS have been adopted to analyze migrating substances from FCMs, like polycyclic aromatic hydrocarbons [78], dibutyltin maleate, and tributyltin chloride [79]. Meanwhile, the sample pretreatment technology corresponding to the rapid detection method also needs to be developed.…”

Excessive absorption of migrating substances from food contact materials can affect human health. Thus, it is essential to analyze the migration of contaminant from food contact materials. However, comprehensive analysis has been challenged by low concentration of migrating substances, manifold and complex matrix interference of food contact materials. Therefore, appropriate sample pretreatment methods should be applied before instrumental detection, which is essential to improve the analytical efficiency, sensitivity, and reliability. This paper systematically reviews the development of sample pretreatment methods for analysis of migrating substances from food contact materials in the past decade. To extract volatile and semi‐volatile substances, headspace extraction, headspace solid phase microextraction, and purge and trap technique are discussed. For non‐volatile substances, solid–liquid extraction and field‐assisted extraction are usually used to extract them from food contact materials, while liquid–liquid extraction, solid phase extraction, and their corresponding microextraction techniques play important roles on enrichment process. In addition, new progress in developments of sample pretreatment methods of food contact materials is summarized, covering new devices, specific adsorbents, and sample preparation methods for rapid detection. An outlook of future prospect of sample pretreatment, especially for non‐targeted analysis of non‐intentionally added substances is briefly discussed.

“…The synthesis of spheroidal silver nanoparticles was adapted from a previously reported preparation [33][34][35]. Briefly, silver nitrate was reduced by sodium borohydride under controlled condition of temperature to produce seeds with a diameter of about 4 nm which were used as starters to the subsequent growth of larger nanoparticles based on the stepwise seeded-growth method.…”
