“…In this study, the following values were found in yoghurt samples as; DEHP 24-122 µg/kg, DBP 46-229 µg/kg, BBP 22-63 µg/kg, In this study, the results are higher than the values found by Sorensen, 2006 (22). Similarly to our study, Sireli et al (2017) 2011) in this study which they examined 9 types of phthalate esters in dairy products; in all the samples the main phthalate ester was DBP with a value of 100 ng / kg. The other results are similar to our study (24).…”

This study was aimed to determine the presence and amount of the phthalates in yoghurt and ayran samples consumed in Turkey. For this purpose, 36 yoghurt and 24 ayran samples were used as materials in original packages collected from different markets in Turkey. The presence and the amounts of di-n-butyl phthalate (DBP), di (2-ethylhexyl) phthalate (DEHP), benzyl butyl phthalate (BBP), di-isononyl phthalate (DINP), di-n-octyl phthalate (DNOP) and diisodecyl phthalate (DIDP) were determined by liquid chromatography/tandem mass spectrometry (LC-MS/MS). The results of the analysis howed that DBP, DEHP and BBP were present in the yoghurt samples whereas DINP, DIDP and DNOP were found to be lower than the detectable limit 20 µg/kg. The lowest and the highest mounts of DBP, DEHP and BBP in yoghurt samples are 6-229, 24-122, 22-63 µg/kg respectively. The lowest and highest phthalate amounts in ayran samples are determined to be 38-59 µg/kg for DBP and 26-81 µg/kg for DEHP. According to the results, although DEHP and DBP were the main phthalate esters in all milk products that were analyzed, the phthalate values of the samples were found to be less than the limit values (P<0.001).

“…According to the research of Ustun et al, DEHP concentrations of soda, lemonade, mineral water and high-taste water in Turkey ranged from 73 to 2312 ng/g and the highest DEHP concentration was found in Cola soft drink [21]. In contrast, based on the study of Sireli et al, DEHP concentration in fruit juice drink varies from 1.1 to 44.3 ng/g, which is much lower than Ustun’ research [26]. Wu et al reported that the DEHP content in energy drink and tea ranged from 15 to 83 ng/g [27].…”

“…Relying on the studies of Guo [28] and Sireli [26], we calculated the daily intake of DEP, DBP, BzBP and DEHP in Vietnam following the formula below:EDI=CQbwruptake where EDI (µg/kg × day) is the estimated daily intake from drinking beverages, C (ng/g) is the phthalate concentration in beverages, r is the gastrointestinal uptake factor and bw (kg) is the body weight. In this study, average beverages intake was 150 g/day, r uptake was 1 and an average bw of 50 kg was used for Vietnam population.…”

A novel method was developed for the sensitive, cheap and fast quantitation of 10 phthalates in non-alcoholic beverages by liquid–liquid extraction (LLE) combined with gas chromatography tandem mass spectrometry (GC-MS/MS). The best results were obtained when n-hexane was used as extraction solvent. A central composite design (CCD) was applied to select the most appreciated operating condition. The method performance was evaluated according to the SANTE/11945/2015 guidelines and was linear in the 0.1 to 200 µg/L range for 10 phthalate compounds, with r2 > 0.996 and individual residuals <15%. Repeatability (RSDr), within-laboratory reproducibility (RSDwr), and the trueness range were from 2.7 to 9.1%, from 3.4 to 14.3% and from 91.5 to 118.1%, respectively. The limit of detection (LOD) was between 0.5 to 1.0 ng/L and the limit of quantitation (LOQ) was between 1.5 to 3.0 ng/L for all 10 compounds. The developed method was successfully applied to the analysis of non-alcoholic beverages.

“…The detection limit was calculated to be 1.3 nmol L −1 from 3 σ / K , where K is the slope of the calibration line and σ is the standard deviation of blank measurements. The performance of MIPs@QDs was compared with that of other methods and the results are summarized in Table . As compared to most of the methods used, the study revealed MIPs@QDs to possess better linear range and lower detection limit.…”

This work describes the preparation of molecularly imprinted polymers using ZnO quantum dots, which were used for the selective detection of diethylhexyl phthalate (DEHP). Methacrylic acid, ethylene glycol dimethacrylate, 2,2′‐azobis(2‐methylpropionitrile) and ZnO were used as functional monomer, crosslinker, initiator and optical material, respectively. Molecularly imprinted polymers were successfully synthesized, and the linear relationship between fluorescence intensity and amount was from 0.5 to 40 µmol L−1 for DEHP. The coefficient of correlation was 0.9923 and the imprinting factor was 11.16. The results were above 97.50% and relative standard deviation below 3.86% for the detection of DEPH in actual water samples. This study could provide a novel method using molecularly imprinted polymers for highly selective and sensitive detection of DEHP. © 2018 Society of Chemical Industry
