“…Beverages can be easily contaminated by phthalate esters during packaging, transportation, and storage processes. Due to complexity of the sample matrix and the low levels of phthalates in food and beverages, determining phthalates in beverage samples is a challenging task [17,35,36]. Temperature and content of a PET bottles play a vital role in determine the rate and extent of leaching of chemicals from the bottle matrix into the water and beverages.…”

Phthalates are commonly used plasticizers in the production of polyvinyl chloride and polyethylene terephthalate plastics. However, due to their extensive use, phthalate esters are considered as ubiquitous environmental pollutants. Beverages and packaged milk are susceptible to contamination by phthalate ester during packaging, transportation, and storage process. This research aimed to quantify the leaching of phthalate esters from commercial beverages and milk samples stored in plastic bottles. Ultrasound and vortex assisted dispersive liquid-liquid microextraction, followed by high performance liquid chromatography were used to analyze selected samples stored under various environmental conditions. The findings showed that beverage bottles stored outdoor exhibited the highest chance of phthalate leaching, followed by those stored at room temperature and 4ºC. The concentration of dibutyl phthalate increased from 3.45 µg/ml (detection on purchase day) to 4.22 µg/ml (detection on expiry day) average on the milk samples, while there was a significant increase in the concentration of diethyl phthalate upon expiray compared to its concentration in fresh milk samples (3.33-11.91 µg/ml) average on all samples. An average of 9.41 and 8.55 µg/ml, 11.4 and 9.23 µg/ml, 20.75 and 17.72 µg/ml of diethyl phthalate and dibutyl phthalate were detected at 4ºC, room temperature and outdoor beverage samples after four months of their storage.This study suggests that the inappropriate storage conditions of milk and beverages enhances the leaching of phthalate esters from plastic matrix into the contained beverages and milk. Although the leaching is slow, continuous usage may pose health effect.

“…10,11 Thus, it is critical to determine the content of DBP in rivers, soil and food. At present, many methods have been developed to detect it, such as high-performance liquid chromatography (HPLC), 12 gas chromatography mass spectrometry (GC-MS), 13 and dispersive liquidliquid micro-extraction (DLLME). 14 Among them, HPLC is a mature and commonly used approach due to its excellent ability of anti-interference and high accuracy for trace pollutants, which can determine samples with poor thermal stability and high molecular weight.…”

With the increasing use of plastic product, there is a large amount of plastic waste containing plasticizer, especially dibutyl phthalate (DBP), which would pollute the water and soil, and even cause diseases to humans and wildlife. Normally, the DBP in soil or water is trace, making it hard to be detected exactly. To solve this case, core‐shell structured molecularly imprinting polymers (P‐MIPs) were synthesized. Combing with photoresponsive monomer 4‐[(4‐methacryloyloxy) phenylazo] benzenesulfonic acid (MAPASA), the prepared P‐MIPs can be controlled by light to specifically absorb (440 nm or darkness condition) and release (365 nm) DBP, with the absorption capacity of 4.45 mg g−1 and imprinting factor of 3.56. More important, the P‐MIPs exhibit excellent reusability and practicability by applied to enrich and extract DBP in river water samples. In conclusion, the proposed P‐MIPs offer an idea for the detection of trace pollutants.

Liquid-phase microextraction based on gemini-based supramolecular solvent was successfully applied as a preconcentration step before gas chromatography with mass spectrometry. To eliminate the interferences of gemini surfactant, the analytes were back-extracted into an immiscible organic solvent in the presence of ultrasonic sound waves. Three phthalate esters (di-n-butyl-, butylbenzyl-, bis(2-ethylhexyl)-, and di-n-octyl phthalatic esters) were used as target analytes. The effective parameters on extraction efficiency of the target analytes (i.e., the amount of surfactant and volume of propanol as major components making up the supramolecular solvent, ionic strength, hexane volume, and ultrasound time) were investigated and optimized by a one-variable-at-a-time method. Under the optimum conditions, the preconcentration factors of the analytes were in the range of 95-182. The linear dynamic range of 0.05-200.00 μg/L with a correlation of determination of (R ) ≥ 0.9935 was obtained. The proposed method had an excellent limit of detection (S/N = 3) of 0.01 for di-n-octyl and 0.02 μg/L for butylbenzyl- and di-n-butyl-phthalatic ester. Good relative recoveries in the range of 85.7-105.2% guaranteed the accuracy of the amount of phthalates distinguished in the nonspiked samples.
