Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

Allergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Nanoplastics Enhance Transmembrane Transport and Uptake of Carcinogens: Transcriptional Changes and the Effects of Weathering

Advanced Science
Nanoplastics are generated from common consumer plastics (polyethylene terephthalate, high‐density polyethylene, polystyrene, polyvinyl chloride) and exposed to simulated marine weathering for up to 10 weeks. Fourier‐transform infrared spectroscopy and ζ‐

Micro‐Nanoplastics Significantly Increase Adverse Events and Economic Burden Associated With Carotid Endarterectomy: A Health Economic Modelling Evaluation

ANZ Journal of Surgery, EarlyView.
Current research reports that micro‐nanoplastics may increase the burden of cardiovascular disease with significant human and economic consequences. The detection of plastic particles in biological matrices is challenging and rigorous research is required to investigate the clinical and broader public health implications of microplastics.

In vivo and In vitro assessment of the retinal toxicity of polystyrene nanoplastics

Environment International
Plastic pollution has emerged as a critical global environmental challenge, yet the effects of the ingested plastic particles on ocular health remain largely unexplored. In this study, we investigated the impact of orally ingested polystyrene nanoplastics (PS-NPs) on the mouse retina.

Mechanism of Growth Phase-Dependent Nanoplastic Bioaccumulation in Tetrahymena thermophila

Antioxidants
Nanoplastics are ubiquitous in aquatic environments, and elucidating their bioaccumulation behavior is essential for assessing toxicity and trophic transfer risks.

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

Physiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Mixture toxicity of 6PPD-quinone and polystyrene nanoplastics in zebrafish

Environmental Pollution
Plastic pollution, including micro- and nanoplastics, is a growing concern. Tyre-wear particles (TWPs) are the second largest source of microplastics in the ocean following abrasion of synthetic fibres. In addition to the particles themselves, TWPs contain many harmful chemicals, including 6PPD. This chemical reacts with atmospheric ozone and forms the

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

Identification of Nanoplastics by Probing the Viscous Nanoenvironment

Small Science
With the growing prevalence of global microplastic and nanoplastic pollution, the accumulation of nanoplastics in the human body has increased, heightening the risk of noncommunicable diseases including cancer, cardiovascular disease, and amyotrophic ...
