Evaluation of bioaccumulation of nanoplastics, carbon nanotubes, fullerenes, and graphene family materials

Environment International, 2023
Bioaccumulation is a key factor in understanding the potential ecotoxicity of substances. While there are well-developed models and methods to evaluate bioaccumulation of dissolved organic and inorganic substances, it is substantially more challenging to

Accelerating Biosensor Discovery: A Computationally‐Driven Pipeline for Microplastics Monitoring

Advanced Intelligent Discovery, EarlyView.
A computationally guided pipeline unites molecular simulation, synthetic biology, electrochemical engineering, and machine learning to accelerate biosensor discovery. A Bacillus anthracis carbohydrate‐binding module is used to develop a high‐performance micro‐ and nanoplastics sensor with greatly reduced error and variability.

Effects of microplastics and nanoplastics on the kidneys

Nephrology Dialysis Transplantation
ABSTRACT Plastics are hydrophobic carbon polymers with a half-life of ∼500 years. The widespread production and environmental accumulation of plastics pose significant toxicity concerns. Humans are routinely exposed to micro- and nanoplastics (MNPs), which can enter rate the bloodstream and reach various organs, including the kidneys ...

PAH Sorption to Nanoplastics and the Trojan Horse Effect as Drivers of Mitochondrial Toxicity and PAH Localization in Zebrafish

Frontiers in Environmental Science, 2020
Plastics are world-wide pollutants that pose a potential threat to wildlife and human health. Small plastic particles, such as microplastics and nanoplastics, are easily ingested, and can act as a Trojan Horse by carrying microorganisms and pollutants ...

Ototoxicity of polystyrene nanoplastics in mice, HEI-OC1 cells and zebrafish

Frontiers in Molecular Neuroscience
Polystyrene nanoplastics are a novel class of pollutants. They are easily absorbed by living organisms, and their potential toxicity has raised concerns. However, the impact of polystyrene nanoplastics on auditory organs remains unknown.

Exposure to micro‐ and nano‐plastics: From human internal burden to systems‐level health‐risk interpretation

iMeta, EarlyView.
Micro‐ and nano‐plastics (MNPs) can enter the human body through inhalation, ingestion, contact with consumer products, and iatrogenic routes. The clinical relevance of MNP exposure should be interpreted at three levels: barrier interaction, cellular stress, and system‐level disruption, with key mechanisms including oxidative stress, mitochondrial ...

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Polyvinyl chloride nanoplastics induce lipid metabolism reprogramming of macrophages

Nano Research
Nanoplastics are increasingly detected in human tissues, yet their biological interactions and health effects remain poorly understood. Here, we show that polyvinyl chloride (PVC) nanoplastics change lipid metabolism of macrophages such as the induced ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...
