This study describes a methodology for evaluating regulatory levels of phthalate contamination. By collecting experimental data on short-term phthalate migration using thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS), the migration of di(2-ethylhexyl) phthalate (DEHP) from polyvinyl chloride (PVC) to polyethylene (PE) was found to be expressed by the Fickian approximation model, which was originally proposed for solid (PVC)/liquid (solvent) migration of phthalates. Consequently, good data correlation was obtained using the Fickian approximation model with a diffusion coefficient of 4.2 × 10−12 cm2/s for solid (PVC)/ solid (PE) migration of DEHP at 25 °C. Results showed that temporary contact with plasticized polymers under a normal, foreseeable condition may not pose an immediate risk of being contaminated by phthalates at regulatory levels. However, as phthalates are small organic molecules designed to be dispersed in a variety of polymers as plasticizers at a high compounding ratio, the risk of migration-related contamination can be high in comparison with other additives, especially under high temperatures. With these considerations in mind, the methodology for examining regulatory levels of phthalate contamination using TD–GC–MS has been successfully demonstrated from the viewpoint of its applicability to solid (PVC)/solid (PE) migration of phthalates.

“…Multi-shot Py-GC/MS has proven to be a good tool for the identification of OPAs and polymers, helping with the identification of additives and simplifying the interpretation of the polymer spectra by separating the additives detection from the polymers and thermally separating the different families of compounds at different temperature intervals (Dekiff et al, 2014;Fries et al, 2013;Herrera et al, 2003;Jansson et al, 2007;Odermatt et al, 2003). In 2019, Yanagisawa et al (2019) The chemical nature of the additives needs to be taken into account. For instance, certain OPAs that are polar, unstable, or have high molecular weight and low volatility, such as some flame retardants or some antioxidants and light or UV stabilizers, are more complex to analyse than others (Riess et al, 2000;Yanagisawa et al, 2018).…”

“…More and more studies are showing interest for this application (Net et al, 2015). However, relatively few studies have managed to attain suitable quantification or semiquantification of additives in polymers, with lacking information on the limits of detection or accuracy of the method for some studies (Table 2) and only on specific families of additives, mostly involving plasticizers especially phthalates (Fries et al, 2013;Kim et al, 2016;Kudo et al, 2019;La Nasa et al, 2021;Maruyama et al, 2015;Net et al, 2015;Yanagisawa et al, 2019) and BFRs (Rial-Otero et al, 2009;Yanagisawa et al, 2018).…”

This study aims to provide a simple way to identify the possibility of Tetrabromobisphenol A (TBBPA) present in polymers without the need for complicated separation with expensive equipment. Since the presence of phenolic hydroxyl groups is known to be identifiable by the reduction of Fe 3+ to Fe 2+ in a ferric coloring reagent, the possibility of TBBPA present in a polymer can be screened by a photometric measurement. A mixed solution of iron (III) nitrate and potassium hexacyanide (III) acid was used as a ferric coloring reagent. With this method, the concentration of TBBPA can be estimated from the photometric absorbance corresponding to the depth of the blue color produced by the reduction of the ferric reagent in the presence of Fe(NO3)3. The limit of detection (LOD) was determined to be approximately 2 mg/kg using the Student's t-test (99% confidence), and a reproducibility of approximately 3% was determined by the relative standard deviation (RSD) from measurements of calibration samples (n = 7). Furthermore, TBBPA in actual polymer samples was screened without the need for any complex processing steps. Because this colorimetric method measures TBBPA by detecting phenolic groups, it may overestimate the TBBPA concentration in the presence of other similar phenolic substances. Nonetheless, this simple colorimetric method should help to quickly identify the presence of TBBPA in various polymers.
