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.

Nanoplastics transport to the remote, high-altitude Alps [PDF]

, 2021
Plastic materials are increasingly produced worldwide with a total estimated production of >8300 million tonnes to date, of which 60% was discarded. In the environment, plastics fragment into smaller particles, e.g.

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 ...

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

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

Environmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

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.

Formation and Identification of Small Microplastics and Nanoplastics [PDF]

, 2022
Plastic production has continued to increase globally and is now a major contaminant across different environments and water systems. Plastic pollution consists of large intact pieces, but also small, fragmented pieces of plastic, termed microplastics ...

Airborne polystyrene nanoplastic exposure leads to splenic cell senescence and immune imbalance

Ecotoxicology and Environmental Safety
Recently, the widespread detection of microplastics and nanoplastics in the human body and their potential health risks have aroused global concern. As nanoplastics are much smaller than microplastics in diamter, their features, such as larger specific ...

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.
