Archives of Toxicology, Journal Year: 2023, Volume and Issue: 98(1), P. 1 - 73

Published: Oct. 19, 2023

Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) and one of the most produced synthetic compounds worldwide. BPA can be found in epoxy resins polycarbonate plastics, which are frequently used food storage baby bottles. However, bind mainly to estrogen receptors, interfering with various neurologic functions, its use a topic significant concern. Nonetheless, neurotoxicity has not been fully understood despite numerous investigations on disruptive effects. Therefore, this review aims highlight recent studies implications system. Our findings suggest that exposure impairs structural molecular brain changes, promoting oxidative stress, changing expression levels several crucial genes proteins, destructive effects neurotransmitters, excitotoxicity neuroinflammation, damaged blood-brain barrier function, neuronal damage, apoptosis effects, disruption intracellular Ca

It has been shown that polystyrene nanoplastic (PS-NP) exposure induces toxicity in the lungs. This study aims to provide foundational evidence corroborate ferroptosis and abnormal HIF-1α activity are main factors contributing pulmonary dysfunction induced by PS-NP exposure. Fifty male female C57BL/6 mice were exposed distilled water or 100 nm 200 PS-NPs via intratracheal instillation for 7 consecutive days. Hematoxylin eosin (H&E) Masson trichrome staining performed observe histomorphological changes To clarify mechanisms of PS-NP-induced lung injury, we used μg/ml, μg/ml 400 treat human bronchial epithelial cell line BEAS-2B 24 h. RNA sequencing (RNA-seq) cells was following The levels glutathione, malondialdehyde, ferrous iron (Fe2+), reactive oxygen species (ROS) measured. expression ferroptotic proteins detected tissues Western blotting. blotting, immunohistochemistry, immunofluorescence evaluate HIF-1α/HO-1 signaling pathway activity.

Airborne microplastics detected in the lungs of wild birds in Japan

Chemosphere, Journal Year: 2023, Volume and Issue: 321, P. 138032 - 138032

Published: Feb. 3, 2023

Microplastics (MPs) have been found in a wide range of animal species including humans. The detection MPs human lungs suggests that humans inhale airborne microplastics (AMPs). Although birds respire more efficiently than mammals and are therefore susceptible to air pollution, little is known about their inhalation exposure MPs. In this study, we analyzed samples isolated from the several wild Japan by attenuated total reflection (ATR) imaging method micro-Fourier transform infrared (μFTIR) spectroscopy clear whether AMPs can be inhaled accumulate within birds. To isolate lung rock doves (Columba livia), black kites (Milvus migrans), barn swallows (Hirundo rustica) euthanized for pest control, digestion density separation were performed. After each sample collected on an alumina filter was measured ATR using μFTIR spectroscopy, physical chemical characteristics detected evaluated. Six 3 22 samples. Polypropylene polyethylene ethylene vinyl acetate swallow. Most fragments 28.0-70.5 μm. Our results demonstrated addition dietary sources, some exposed inhalation, these reach lungs.

Recent Advances in Microplastics Removal from Water with Special Attention Given to Photocatalytic Degradation: Review of Scientific Research

Microplastics, Journal Year: 2023, Volume and Issue: 2(3), P. 278 - 303

Published: Sept. 4, 2023

Microplastic pollution has become a global environmental concern with detrimental effects on ecosystems and human health. Effective removal of microplastics from water sources is crucial to mitigate their impacts. Advanced oxidative processes (AOPs) have emerged as promising strategies for the degradation elimination microplastics. This review provides comprehensive overview application AOPs in water. Various AOPs, such photocatalysis, ozonation, Fenton-like processes, shown significant potential microplastic degradation. These generate highly reactive species, hydroxyl radicals, which can break down into smaller fragments or even mineralize them harmless byproducts. The efficiency photocatalytic oxidation depends several factors, including choice photocatalysts, reaction conditions, physicochemical properties Furthermore, this discusses challenges associated oxidation, need optimization operating parameters formation harmful Overall, offers avenue water, contributing preservation aquatic safeguarding However, further research needed address limitations optimize implementation process effective sustainable remediation.
