“…Zero-iron TiO2 24. 4 High-resolution XPS spectra for the iron region ( Figure 3) was studied only for 1.0 Fe-TiO2 because no Fe2p signals were detected for zero-iron TiO2, 0.3 Fe-TiO2, or 0.6 Fe-TiO2. The deconvolution of high-resolution XPS spectra ( Figure 3) was developed for previously reported peaks of Fe 2+ and Fe 3+ [43].…”

“…Natural hormones (e.g., estrone (E1), 17β-estradiol (E2), and estriol (E3)) as ECs are susceptible of persisting and bioaccumulating in the environment, and could induce endocrine disruption in humans and wildlife (vertebrates [3][4][5] and invertebrates [6,7]). Natural attenuation, drinking water purification, and conventional municipal wastewater treatment processes are either incapable or only partially capable of removing estrogens from water [8].…”

Iron-doped TiO2 nanoparticles (Fe-TiO2) were synthesized and photocatalitically investigated under high and low fluence values of UV radiation. The Fe-TiO2 physical characterization was performed using X-ray Powder Diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area analysis, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Diffuse Reflectance Spectroscopy (DRS), and X-ray Photoelectron Spectroscopy (XPS). The XPS evidenced that the ferric ion (Fe3+) was in the TiO2 lattice and unintentionally added co-dopants were also present because of the precursors of the synthetic method. The Fe3+ concentration played a key role in the photocatalytic generation of hydroxyl radicals (•OH) and estriol (E3) degradation. Fe-TiO2 accomplished E3 degradation, and it was found that the catalyst with 0.3 at.% content of Fe (0.3 Fe-TiO2) enhanced the photocatalytic activity under low UV irradiation compared with TiO2 without intentionally added Fe (zero-iron TiO2) and Aeroxide® TiO2 P25. Furthermore, the enhanced photocatalytic activity of 0.3 Fe-TiO2 under low UV irradiation may have applications when radiation intensity must be controlled, as in medical applications, or when strong UV absorbing species are present in water.

“…Xenoestrogens, is a known endocrine-disrupting chemicals (EDCs), have extensively adverse effects on human and animal health (Dimogerontas, G., & Liapi, C. 2013). Bisphenol-A (BPA), one of the most significant xenoestrogens, is produced at approximately 7.2 million tons globally and increases 5% yearly (Tarafdar A. et al, 2022).…”

Bisphenol-A (or BPA) is a renowned endocrine disruptor in current use. This study concentrated on the restorative effects of wheatgrass methanolic extract (WG-ME) on the liver and kidney in rats treated with BPA. For this purpose, 18 Wistar rats were divided into 3 groups: Control; BPA (100mg/kg); BPA+ WG-ME (100 mg/kg BPA + 200mg/kg WG-ME) by oral gavage for 28 days study period. Dissected liver and kidney were procured and stored at -20oC for the evaluation of cellular antioxidant status. For the analysis of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), urea and creatinine levels, which have a role in measuring liver and kidney toxicity, blood samples were collected. In parallel, BPA decreases cellular antioxidant levels super-di-oxide (SOD), catalase and GPx in liver and kidney. The hepato-renal functional tests and antioxidant enzyme levels were significantly improved with the addition of WG-ME oral consumption. These findings provided that protective effect of WG-ME improving BPA-induced metabolic alterations.
