The monitoring of the contamination levels of bisphenol A (BPA) and its congeners bisphenol B (BPB) and bisphenol F (BPF) in foodstuffs is a necessary process for assessment of consumers' risk. After development and validation of a method using Strata® C18-E cartridge cleanup with detection by liquid chromatography coupled to tandem mass spectrometry, forty-six samples of fruit juices, sold on Italian markets, have been analysed to assess the concentration of BPA, BPB and BPF. BPB and BPF were not detected in any samples, BPA was found in 33 % of the samples. The observed levels ranged from 0.50 ng mL to 2.85 ng mL. Potential Daily Intakes (PDI) of BPA for Italian populations were calculated by the budget method model. PDIs ranged from 0.012 to 0.285 μg kg bw day. None of the calculated values exceeded the current temporary TDI of 4 μg kg bw day.

Overlapping peaks can be difficult to avoid in 1D-LC, which make the identification and quantification of compounds ambiguous, especially if the only available detector is a UV/DAD. To overcome this, a two-dimensional liquid chromatography (2D-LC) method to monitor Bisphenols (BPs), and particularly the chosen analogues BPA, BPB, BPF, BPS, BPZ, and BPAF, in a complex matrix (canned food) was developed and validated. BPs are endocrine disruptors present in the lining of the can, which may leach into the content of canned food.

To address the under-researched risk of bisphenols (BPs) in e-cigarette liquids, comprehensive studies have been conducted to propose optimum sample preparation and analysis methods. To determine twelve BPs in refill liquids for e-cigarettes, three sample preparation methods based on distinct operational and working principles were employed. These included fabric phase sorptive extraction (FPSE), ultrasound-assisted solvent extraction of porous membrane-packed samples (UASE-PMS) and solid phase extraction (SPE) utilizing molecularly imprinted polymers (MIPs) technology.

Cytotoxic impacts of seven alternative bisphenols on human in vitro cellular models.

Chemosphere

October 2024

Department of Environmental Science, Baylor University, Waco, TX, 76798, USA. Electronic address:

Bisphenols (BPs), common in plastics, coatings, and resins, are under scrutiny for potential endocrine disruption. Despite banning bisphenol A (BPA), its perceived safer alternatives may still pose health risks, urging thorough studies on their toxicity mechanisms. This study aimed to investigate the cellular toxicity of the top seven most commonly used BPs, bisphenol S (BPS), bisphenol F (BPF), bisphenol AF (BPAF), bisphenol P (BPP), bisphenol AP (BPAP), bisphenol B (BPB), bisphenol E (BPE) in eight different relevant human in vitro cell models: liver (HepaRG), intestinal (Caco-2), breast (T47D), brain (HMC-3), lungs (MRC-5), kidney (HEK293), endothelial (HMEC-1), and skin (HEK-001) cell lines.

Luminescent Metal-Organic Framework-Based Fluorescent Sensor Array for Screening and Discrimination of Bisphenols.

Inorg Chem

October 2024

School of Emergency Management, School of the Environment and Safety Engineering, Jiangsu University, Zhenjiang 212013, China.

Extensive applications of bisphenols in industrial products have led to their release into aquatic environments, causing a great threat to human health due to their endocrine-disrupting effects, whereas existing methods are difficult to implement the rapid and high-throughput detection of multiple bisphenols. To circumvent this issue, we constructed a sensor array using two luminescent metal-organic frameworks (LMOFs) (Zr-BUT-12 and Ga-MIL-61) for the rapid discrimination of six bisphenol contaminants (BPA, BPS, BPB, BPF, BPAF, and TBBPA). Wherein, Zr-BUT-12 and Ga-MIL-61 exhibited different fluorescence-emission properties and good luminescent stability.

Impact of Bisphenol A and its alternatives on oocyte health: a scoping review.

Hum Reprod Update

December 2024

School of Biomedical Science and Pharmacy, College of Health, Medicine, and Wellbeing, University of Newcastle, Callaghan, NSW, Australia.

Background: Bisphenol A (BPA) is an endocrine disrupting chemical released from plastic materials, including food packaging and dental sealants, persisting in the environment and ubiquitously contaminating ecosystems and human populations. BPA can elicit an array of damaging health effects and, alarmingly, 'BPA-free' alternatives mirror these harmful effects. Bisphenol exposure can negatively impact female fertility, damaging both the ovary and oocytes therein.
