Bisphenol A (BPA) substitutes, such as bisphenol S (BPS) and bisphenol AF (BPAF), are increasingly used due to restrictions on BPA usage, a known endocrine disrupting chemical and putative obesogen. However, little is known about the obesogenic effects of exposure to BPA substitutes in children. A total of 426 children aged 7 years old originally recruited from Laizhou Wan Birth Cohort in Shandong, China, during 2010-2013 participated in the 2019-2020 survey. Urinary BPA and its substitutes including BPS, BPAF, bisphenol B (BPB), bisphenol AP (BPAP), bisphenol Z (BPZ), and bisphenol P (BPP) were determined. Anthropometric measures including height, weight, waist circumference, and body fat percentage were assessed, and overweight/obesity was defined as BMI z-score ≥ 85th percentile. Linear and logistic regressions were used on continuous and binary obesity measures, respectively, and weighted quantile sum (WQS) regression was further used to estimate the mixture effects of exposure to diverse bisphenols, and sex-stratified analysis was performed. BPA substitutes were widely detected (> 75%) in children's urine samples. A positive association with obesity measures was consistently observed for urinary BPS and BPAF, i.e., BMI z-score, waist circumference, and overweight/obesity. Further analysis from the WQS regression model demonstrated a positive association between bisphenol mixtures and all measures of obesity, with BPAF contributing the greatest weighing to the observed associations. Sex difference might exist as the positive associations were only significant in boys. No significant association was found between obesity and BPA or other BPA substitutes. Our study adds to mounting evidence that BPA substitutes BPS and BPAF are linked to obesity in children, especially in boys. Further longitudinal studies with larger sample size with continued biomonitoring these chemicals and their obesogenic effects are necessary.

Background: Bisphenol F (BPF), a substitute for bisphenol A (BPA), is widely used in consumer products, increasing the potential for environmental exposure. Our study investigated the reproductive effects of BPF on adult male zebrafish and explored its toxicological mechanisms, as well as its intergenerational effects.
Methods: Adult male zebrafish were exposed to BPF concentrations of 0, 50, 500, 2500, and 5000 nM for 21 days.

The effects of bisphenol A (BPA), a highly diffused endocrine-disrupting chemical found mainly in plastics, on neural circuits and behaviors are well-known. However, the effects of its substitutes have not been fully investigated. Thus, in the present study, we compare the effects of perinatal exposure to bisphenol A or S (BPS) on reproductive behaviors and related hypothalamic kisspeptin system in mice.

Color vision, which is mediated by cone photoreceptors in vertebrates, is essential for perceiving the external environment. Bisphenol A (BPA) and its substitute bisphenol S (BPS) have been widely used worldwide, while the evaluation of their safety, especially the newly discovered visual toxicity mechanism caused by them in recent years, has not been clearly explored. In the present study, we investigated the effects of BPA treatment (1, 10, and 100 μg/L) on cone cell development and function to evaluate visual toxicity.

Herein, using 1,3,5-triformylphloroglucinol (Tp) and 4,4',4″-(1,3,5-triazine-2,4,6-triyl) tris(1,1'-biphenyl) trianiline (Ttba) as ligands, nitrogen-rich triazine unit-based covalent organic frameworks (COFs) with a suitable pore size, named TpTtba-COFs, were synthesized, and they were employed as adsorbents for the extraction and detection of three bisphenols (BPs)-BP A (BPA), BP B (BPB), and BP S (BPS)-in water. Using 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (Tapt) and 1,3,5-tris(4-aminophenyl)benzene (Tapb) ligands as substitutes for Ttba, nitrogen-rich triazine unit-based COFs with a smaller pore size and nitrogen-poor triazine unit-based COFs, named TpTapt-COFs and TpTapb-COFs, respectively, were also prepared for comparison. The adsorption performances of the three COF adsorbents with regard to the three BPs were tested.

Endocrine-disrupting chemicals (EDCs) significantly contribute to health issues by interfering with hormonal functions. Bisphenol A (BPA), a prominent EDC, is extensively utilized as a monomer and plasticizer in producing polycarbonate plastic and epoxy resins, making it one of the highest-demanded chemicals in commercial use. This is the major component used in plastic products, including bottles, containers, storage items, and food serving ware.
