“…Most of them originated from foods packed in bottles, and only 2-methyl-1,3-dioxolane was derived from polymer impurities [31]. Another paper also reported that PET materials mainly release some phthalic acid esters (PAEs) and plastic additives by hydrophilic solutions [32]. In addition, as the results show in Table 3, we also did not find PAEs or other plastic additives by GC-MS analysis.…”

A convenient and easy-moving, modified, headspace solid-phase microextraction (HS-SPME) device was developed for monitoring a living plant’s volatile organic compounds (VOCs). It consisted of a polyethylene terephthalate (PET) bottle as a sampling chamber, and certain variables were considered when using the HS-SPME device, including the material used and the fiber position, the direction of the airstream, and the distance between the sample and the fan. The results from varying those factors, generated by the orthogonal array design (OAD) method, were used to optimize the modified HS-SPME conditions. Based on the current literature regarding extracting fragrances by SPME, we selected polydimethylsiloxane/divinylbenzene (PDMS/DVB) and polydimethylsiloxane (PDMS) as the fiber materials. Using the OAD method, PDMS/DVB was found to be the better fiber material when it was parallel to the fan, and also when the airstream provided positive pressure to the sample with the fan near the sample. The device was used to sample biogenic volatile compounds emitted from fresh Nymphaea caerulea (water lily) flowers, followed by gas chromatography-mass spectrometry (GC-MS) analysis. For the method validation, under the optimum conditions, the calculated detection limit value of the model compound (butyl decanoate) was 0.14 ng on column, which was equal to 1.41 ppm for the injection. The relative standard deviations of the intra-day and inter-day precisions were 1.21% and 3.05%. Thirty-three compounds were separated and identified. The main components in the vapor phase of N. caerulea were benzyl acetate (10.4%), pentadecane (15.5%), 6,9-heptadecadiene (40.1%), and 8-heptadecene (15.3%).

“…According to some published literature, the presence of oleamide may be a consequence of the use of a lubricant coating for the cap sealing, applied for easier opening [36,37], or may be introduced into the liquid through some other sources, such as water/liquid processing steps (transport pipelines, pipes, storage tanks, bottling process, filtering systems, disinfection) [36]. Recently, oleamide was found to leach from reusable PET bottles into different water and liquid food samples as well [38]. Erucamide, another fatty acid amide lubricant, which is not a standard additive of PET polymer [35], was also found in mineral water stored in PET containers in concentrations ranging from 2 to 182 ng mL −1 [39].…”

The purpose of the study was to investigate the migration of oleamide, a polymer lubricant, and a bioactive compound, from various plastic, marketed containers for food/beverages and medicines into polymer contact liquid. Methanol, food/medicine simulants or real samples were used to extract polymer leachables and extractables. Migrated oleamide into polymer contact liquids was determined by ultra-high performance liquid chromatography coupled to mass spectrometry (UHPLC-MS). The concentration of oleamide in the extracts of medicinal and insulin syringes was 7351 ng mL−1 and 21,984 ng mL−1, respectively. The leachates of intravenous (i.v.) infusion bottle, medicinal and insulin syringes contained 17 ng mL−1, 12 ng mL−1 and 152 ng mL−1, respectively. Oleamide in the extracts of dummies ranged from 30 to 39 ng mL−1, while in the leachates of baby bottles, from 12 to 23 ng mL−1. Leachates of soft drink bottles contained from 6 to 15 ng mL−1 oleamide, milk bottles from 3 to 9 ng mL−1, liquid yogurt bottles 17 ng mL−1 and water bottles from 11 to 18 ng mL−1. Bottled real matrices of oil and milk contained oleamide in the range from 217 to 293 ng mL−1. Moreover, the source of migrated oleamide (e.g., containers, caps, other parts) was identified. Oleamide is listed in the current EU regulations without a specific migration limit. Accordingly, these values are considered of no concern, unless future toxicological studies prove the opposite.

“…As can be seen, the chromatograms are clear, which means that the extraction procedure is effective and that the peaks are sharp and well resolved. For a complete analytical characterization, a comparison was carried out between our main results and those reported in the literature; in particular, recoveries, LODs and LOQs were compared between different studies performed in the last decade for the simultaneous analysis of PAEs and BPA in food/beverage matrices [51][52][53][71][72][73][74][75][76][77][78] (Table 4). As can be seen, the main basic PAEs analyzed in most papers are DEP, DBP, and DEHP together with BPA, whereas only a few papers show a more complete PAE speciation.…”

“…A similar consideration could be drawn by other authors. Finally, it should be noted that the paper by Gorji et al [77] shows interesting LODs and LOQs, but that the paper is focused only on the determination of five PAEs (with no BPA).…”

A Method Validation for Simultaneous Determination of Phthalates and Bisphenol A Released from Plastic Water Containers

et al. 2019

Phthalates (or phthalate esters, PAEs) and bisphenol A (BPA) are widely used in various industries, particularly in the fields of cosmetics and packaging, and they increase the malleability and workability of materials. As a result of their use, some international health organizations have begun to study them. In this study, the authors developed a methodology for the simultaneous determination of dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP); dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP); di-n-octyl-phthalate (DnOP) and bisphenol A (BPA) from drinking and non-potable waters. The extraction of PAEs and BPA was performed using a solvent-based dispersive liquid–liquid microextraction (SB-DLLME) method. The analytical determination was performed using a gas chromatography–ion trap mass spectrometry (GC-IT/MS) analysis. The entire procedure was validated as recoveries were studied according to the volume and the extraction solvent used, pH, and ionic strength. Dynamic linearity ranges and linear equations of all the compounds were experimentally determined as well as the limit of detection (LOD) (1–8 ng mL−1) and the limit of quantification (LOQ) (5–14 ng mL−1), reproducibility, and sensitivity. The method was applied to 15 water samples (mineral water and tap water) for determining PAEs and BPA released from the plastic container. After the release simulation, four PAEs (i.e., DiBP, DBP, DHEP, and DnOP) were determined at very low concentrations (below 1.2 ng mL−1) in two water samples from (sport) bottles.
