From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Micro- and nanoplastics in neurological dysfunction

Trends in Neurosciences
Plastic particles can interfere with the nervous system and are increasingly recognised as a global health concern. This review encompasses recent findings on the impact of plastic particles on brain health, including studies in humans, rodents, nematodes, and zebrafish. We discuss how plastics can impact cellular metabolism, affect developmental brain

Angle‐dependent X‐ray absorption correction in small‐ and wide‐angle X‐ray scattering: accounting for constrained scattering volume, beam profiles and capillary wall attenuation

Journal of Applied Crystallography, EarlyView.
We present an improved numerical angle‐dependent absorption correction procedure for line‐collimated small‐ and wide‐angle X‐ray scattering measurements in thin‐walled quartz capillaries. The procedure accounts for the constrained illuminated volume, measured primary beam profiles and capillary‐wall absorption, enabling physically consistent data ...

Mitigating combined internalized toxicity of nanoplastics and cadmium in rice through metabolic and biochemical regulations under supply of biochar biofilters derived from Mikania Micrantha

Biochar
Nanoplastics and cadmium are common pollutants in agricultural systems, posing significant risks to rice. This study explored the effectiveness of biochar biofilters derived from invasive plant Mikania micrantha in mitigating the combined toxicity of ...

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.

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.

Recent progress and future directions of the research on nanoplastic-induced neurotoxicity

Neural Regeneration Research
Many types of plastic products, including polystyrene, have long been used in commercial and industrial applications. Microplastics and nanoplastics, plastic particles derived from these plastic products, are emerging as environmental pollutants that can

Beyond Deterministic Fetal Programming: Intrauterine Exposures and the Multifactorial Origins of Adiposity

Obesity Reviews, EarlyView.
ABSTRACT Excess adiposity is not a recently developed problem but has existed since at least the upper Paleolithic, allowing evolutionary selection pressures to adapt the physiology of the pregnant woman and the feto‐placental unit for maternal and fetal protection.

Microplastics and nanoplastics size distribution in farmed mussel tissues

Communications Earth & Environment
Microplastics and nanoplastics are hazardous to ecosystems, wildlife, and through seafood, also for human health. Due to biological, chemical, and physical characteristics, nanoplastics can slip through cell membranes, being even more toxicologically ...
