Tailoring the synergistic effect of integrated polypyrrole hydrogel on the adsorption activity of rice husk-based activated carbon (polypyrrole/activated carbon composite) for bisphenol-A and 4-chlorophenol: experimental and theoretical analysis

open access: yesFrontiers in Bioengineering and Biotechnology
Rice husk-derived activated carbon was hybridized with polypyrrole hydrogel (Pyh), producing advanced nanocomposite (Pyh/AC). The composite was applied as an enhanced adsorbent for two forms of toxic phenolic compounds, particularly bisphenol-A (BSP-A ...

Comment on “Toxicokinetics of bisphenol A, bisphenol S, and bisphenol F in a pregnancy sheep model”

open access: yesChemosphere, 2019
Gingrich et al. (2019) report a comparative toxicokinetic (TK) study of Bisphenol A (BPA), Bisphenol S (BPS) and Bisphenol F (BPF) in the pregnant ewe model after a single subcutaneous administration of BPS or a mixture of BPA, BPS and BPF. The topic is highly relevant. Unfortunately, many errors were noted in the calculation of TK parameters.

Bisphenol A Induces DNA Damage and Differential Cytotoxicity in Thyroid Cells: High‐Dose Effects Challenge Regulatory Thresholds

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, has been implicated in carcinogenesis; however, its effects on thyroid cells remain unclear. This study investigated BPA‐induced cytotoxicity and genotoxicity in thyroid cell lines, including normal follicular (Nthy‐ori 3‐1), papillary carcinoma (TPC‐1 and BCPAP) and anaplastic
