This study was performed to examine whether bisphenol (BP) A analogues, BPE and BPS, negatively impacts reproductive functions using mice as a model. CD-1 mice were exposed to control treatment (corn oil), BPA, BPE and BPS (50μg/kg or 10mg/kg) from birth to postnatal day (PND) 60 by s.c. injection every three days. Sperm counts or motility was significantly reduced by BPA, BPE or BPS exposure on PND 60 or PND 90. Exposure of BPA, BPE and BPS disrupted the progression of germ cell development, as morphometric analyses exhibited an abnormal distribution of the stages of spermatogenesis. In females, postnatal BPA and BPE exposure accelerated the onset of puberty, and increased body weight after parturition. Furthermore, postnatal exposure of BPA, BPE and/or BPS increased steroid hormone levels in serum. These results suggest that BPA analogues (BPS and BPE) affects male and female reproductive functions.

The safety of bisphenol A (BPA) due to its adverse effects on the immune system has led to an increasing concern and a significant regulatory shift. The European Food Safety Authority (EFSA) proposed a reduction in the tolerable daily intake (TDI) of BPA in food in their 2023 scientific opinion, highlighting the need for stricter regulations compared to their previous assessment in 2015. This regulatory action has spurred the production of BPA alternatives, raising concerns about their safety due to insufficient toxicological data.

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.

Article Synopsis
- Bisphenol A (BPA) is a synthetic chemical linked to harmful health effects like metabolic and reproductive issues, leading to its classification as toxic in the EU and resulting in bans or restrictions on its use.
- Industries have started using alternatives like bisphenol S (BPS) and bisphenol F (BPF), which are also toxic and currently being regulated, while other less-known BPA substitutes are emerging.
- This review highlights the hazards of various BPA alternatives, focusing on their toxicological data related to endocrine disruption, immunotoxicity, and other health risks, with goals to identify knowledge gaps and improve chemical risk assessment methods under the European Partnership for the Assessment of Risks from Chemicals (PARC) project.

Benzotriazoles (BTR) and bisphenols (BP) are artificial contaminants of emerging concern (CECs) commonly found in everyday products. This study focuses on urban runoff to investigate the occurrence of BTRs and BPs in Iceland, regarded as one of the least polluted places in the world, which made it reasonable to confirm or deny the presence of these micropollutants in its environment. Samples collected in February 2023 (SC1) and August 2024 (SC2) from seven locations along Iceland's Ring Road were evaluated to determine the occurrence of seven BTRs (1H-BTR, 4Me-BTR, 5Me-BTR, 5Cl-BTR, UV-P, UV-326, UV-329) and six BPs (BPF, BPE, BPA, BPZ, BPAP, BPM) in the runoff, using the ultrasound-assisted emulsification-microextraction for analytes isolation and gas chromatography-mass spectrometry for detection (USAEME-GC/MS).

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.
