Summary: Regulatory measures and public concerns have led to the replacement of bisphenol A (BPA) in consumer products, but the potential endocrine disruption of BPA alternatives is still under surveillance. This study assessed the placental transfer of 15 selected bisphenols using an ex vivo human placental perfusion model, revealing varying levels of transport efficiency among the bisphenols. The data from this study will be valuable for predicting fetal exposure to these emerging contaminants.

Summary: A novel method using online heart-cutting two-dimensional liquid chromatography (2D-LC) coupled to solid-phase extraction (SPE) was developed for simultaneous separation and detection of chiral antidepressants in wastewater matrix. The method achieved complete enantioseparation and satisfactory transformation between 2D-LCs. The three analytes, namely mirtazapine, bupropion, and fluoxetine, showed good linearity and low LOD and LOQ values. The method was successfully applied to determine the racemates and enantiomers of these antidepressants in wastewater samples, providing an efficient approach for pollution assessment and illicit drug control.

Summary: This study optimized and validated a method based on MSPD and LC-MS/MS for the sensitive and selective determination of chlorhexidine in sludge from STPs. Analysis of samples from different STPs in Northwest Spain revealed the presence of chlorhexidine, which may impact microbial populations but is unlikely to affect plant germination.

Summary: Three carboxyl functionalized porous polymers were synthesized and employed as solid-phase extraction sorbent to enrich phenolic endocrine disrupting chemicals (EDCs) at trace level. Among them, PDA-DPBP showed superior enrichment efficiency due to the strong hydrogen bonding, pore filling, hydrophobic interaction and pi-pi interaction between PDA-DPBP and phenolic EDCs. The method combined with high performance liquid chromatography provided a reliable alternative for sensitive determination of phenolic EDCs in bottled water, juice and milk samples. Overall rating: 8/10.

Summary: In this study, biochar materials derived from carbonizing peanut shells were used as adsorbents for pipette-tip solid-phase extraction (PT-SPE) of six endocrine-disrupting phenols (EDPs). The biochar materials exhibited abundant carbon structures and functional groups that were favorable for the enrichment of EDPs. The optimized PT-SPE method showed good analytical performance and was successfully applied to the determination of EDPs in various samples.
