“…These correlations found in the food samples analysed show that EthPB and PropPB originate from the same sources. However, the source of parabens in foods is not completely understood but their use as broad-spectrum antimicrobial preservatives used in processed foods may be a potential source [ 2 , 3 ] as well as the use of certain food packaging materials where parabens are added as antimicrobials from where they can be released into the food inside [ 46 , 47 , 48 ]. We found no differences in the concentrations and frequency of paraben occurrence among the food in different packaging ( Table 4 , Table 5 and Table 6 ).…”

Given the widespread use of bisphenols and parabens in consumer products, the assessment of their intake is crucial and represents the first step towards the assessment of the potential risks that these compounds may pose to human health. In the present study, a total of 98 samples of food items commonly consumed by the Spanish population were collected from different national supermarkets and grocery stores for the determination of parabens and bisphenols. Our analysis demonstrated that 56 of the 98 food samples contained detectable levels of parabens with limits of quantification (LOQ) between 0.4 and 0.9 ng g−1. The total concentration of parabens (sum of four parabens: ∑parabens) ranged from below the LOQ to 281.7 ng g−1, with a mean value of 73.86 ng g−1. A total of 52% of the samples showed detectable concentrations of bisphenols. Bisphenol A (BPA) was the most frequently detected bisphenol in the food samples analysed, followed by bisphenol S (BPS) and bisphenol E (BPE). Bisphenol AF (BPAF), bisphenol B (BPB) and bisphenol P (BPP) were not found in any of the analysed samples. LOQ for these bisphenols were between 0.4 and 4.0 ng g−1.

“…There are numerous ex situ methods available to quantify the presence of parabens and their derivatives. Some of the generally used ex situ techniques include high-performance liquid chromatography (HPLC), solid-phase extraction and gas chromatography–mass spectrometry (SPE/GC-MS), dispersive liquid–liquid microextraction (DLME-HPLC-MS), liquid chromatography–tandem mass spectrometry (LC-MS/SPE), capillary electrophoresis, and spectrophotometry . Although these techniques are generally performed in laboratory settings with low detection limits and high accuracy, they possess several drawbacks like being time-consuming, requiring highly trained personnel to operate the instrument, and needing tedious sample preparation and extraction techniques.…”

Paraben, a conventional preservative used in most personal care products, falls under the class of endocrine disruptors. From small living organisms to human beings, everyone is exposed to this endocrine disruptor either directly or indirectly. Paraben has quite treacherous effects, causing numerous effects on every living being. Hence, there is a necessity to spot the presence of this molecule in personal care products to validate its usage limit and also in water samples since it acts as a major pollutant by accumulating in many water bodies as a result of wash-off from many day-to-day products. In this work, an electrochemical sensor has been designed using a hybrid nanomaterial as a chemical modifier, i.e., polyhedral oligomeric silsesquioxane terminated with vinyl groups (POSS-vinyl). This modifier effectively quantifies the target analyte’s presence avoiding matrix effects in cosmetic products as well as in simulated water samples with excellent recoveries. This material is subjected to various physiochemical characterizations, revealing that the synthesized material is a POSS-vinyl oligomer. The electrochemical characterization discloses its sensing ability toward parabens by offering sensitivities of around 0.0103, 0.0048, and 0.0078 μA/μM and detection limits of about 0.29, 0.36, and 0.38 μM for methyl, ethyl, and propyl parabens, respectively.
