A critical review of micro- and nanoplastic permeation in the human body
Abstract Plastic products have been progressively integrated into every aspect of human life, and they are susceptible to fragmentation, leading to the release of micro- and nanoplastics (MNPs) to the surroundings. Not only are these persistent particles ubiquitous in the environment, but they have…

Oral exposure to polyethylene microplastics exacerbates the effects of a Western-style diet on the digestive tract of adult male mice
Abstract Microplastic pollution is a growing global concern, yet the human health effects of exposure to microplastics, particularly in interaction with dietary factors, are not well understood. In this study, we investigated the impact of polyethylene microplastics (PE-MPs) on intestinal…

Method for quantification of microplastic release from plastic-based materials during weathering
Abstract Most microplastics (MPs) are generated as a result of photodegradation during the life of plastic products and after the end-of-life as mismanaged waste. At present, it is impossible to avoid plastic-based materials altogether because of their unique properties, versatility, and price. An…

Microplastic ingestion induces changes in coelomocyte composition of Eisenia fetida
Abstract The earthworm Eisenia fetida is a widely used model organism for environmental toxicity assessment, including microplastic particles (MPP). Impacts of MPP at the organism level have been extensively documented, while effects on the cellular level and in particular the immune system of E…

Top-down generated microplastics differentially induce neutrophil cell death associated with phagocytosis
Abstract Micro- and nanoplastics (MNPs) are able to cross the epithelial barriers, enter the circulation and encounter immune cells. Unlike bacteria or viruses, MNPs cannot be degraded by immune cells and may therefore pose a potential risk to human health. Neutrophils are the most predominant…

Using the power law size distribution to extrapolate and compare microplastic number and mass concentrations in environmental media
Abstract Studies reporting environmental microplastic (MP) concentrations typically do so for variable MP size ranges, depending on sampling, processing and analytical detection methods. However, MP number concentrations in the environment increase exponentially with decreasing particle size. This…

Colorful attire and tailored protocols enhance traceability and mitigate contamination in biota microplastic research
Abstract Sample contamination remains a major obstacle to microplastic research; however, evaluations of mitigation strategies are scarce. This study synthesized 89 mitigation measures derived from literature, laboratory observations, and literature-based measures adapted to laboratory conditions…

Combination of oil-based separation and differential scanning calorimetry towards a methodological setup for microplastic analysis in sediments
Abstract Analyzing microplastics (MP) and nanoplastics (NP) in sediments remains challenging due to low particle concentrations and complex sample composition. We present an integrated workflow combining oil-based separation with differential scanning calorimetry (DSC) for the isolation and thermal…

Microplastics detection in agricultural soil combining 3D Laser Scanning Confocal Microscopy with machine learning
Abstract Accurate quantification of microplastics (MPs) in soils remains analytically challenging due to complex mineral and organic soil matrices. Microscopy, spectroscopy and thermoanalytical techniques are widely applied to analyse MPs in soils. However, integrated workflows enabling…

Evaluating cellular effects of PET microplastics in 2D/3D models: viability, oxidative stress, and comprehensive methodological considerations
Abstract Despite the widespread environmental contamination by micro- and nanoplastics (MNPs), the cellular toxicity of polyethylene terephthalate (PET) particles is poorly understood. Here, we assessed pristine PET-Micro- and nanoplastic particles (MNPs) (diameter: 1.24 ± 0.52 µm) and…

Size- and matrix-independent SERS quantification of polystyrene nanoplastics using interfacially assembled AgNPs@CTAB films
Abstract Reliable quantification of nanoplastics (NPLs) in aquatic environments remains challenging due to their small size and limited hotspot accessibility in conventional SERS systems. Herein, a facile two-phase interfacial assembly strategy was developed to fabricate a uniform and reproducible…

Detection limits of soil microplastics using mid-infrared spectroscopy
Abstract Microplastic (MP) pollution in agricultural soils presents emerging risks to soil health, crop productivity, and food safety, yet detecting MPs at low concentrations remains difficult. This study establishes an innovative mid-infrared (MIR) spectroscopy framework combining spectral…

Enhanced separation of microplastics using silanized sand
Abstract Sand filtration is one of the important unit operations at water and wastewater treatment plants contributing to the separation of microplastic contaminants. However, its performance against especially the smaller-sized microplastic particles is not satisfactory. In this study, this…

Tracking the UV-induced photo-oxidation of polyolefins at the particle level using FT-IR imaging of immobilized microplastics
Abstract Detection of microplastics typically relies on Fourier-transform infrared (FT-IR) Imaging combined with spectral matching to reference polymer databases. However, these databases often lack truly representative spectra of environmentally aged particles, particularly those affected by…

Microplastic risks in soils are fragmentation kinetics- and time-dependent
Abstract Ecological risk assessments for microplastics at steady-state environmental concentrations exist, but these are inherently retrospective and do not account for time-dependent fragmentation processes. As plastics degrade into smaller particles, their exposure, bioaccessibility and…

Microplastics predominantly accumulate in CD11b− macrophages of the liver and spleen without overt neutrophil activation
Abstract To estimate the health effects of internal microplastics exposure, it is crucial to understand their dynamics and the effects on immune cells. To confirm that microplastics are transported from the intestinal lumen to the bloodstream, we fed mice 1 µm polystyrene (PS) spheres and analyzed…

Subsampling bias in microplastics research: lessons from literature and numerical simulations
Abstract Subsampling strategies are commonly employed in microplastic research to reduce the analytical burden associated with time-intensive techniques such as microscopy and Fourier-transform infrared (FTIR) spectroscopy. However, these strategies are often applied without prior validation. This…

Polyethylene microplastics mineralize slowly in soil but integrate into soil structures and organic matter
Abstract Polyethylene is the most abundant microplastic in agricultural soils and can alter soil properties and plant health. However, microbial mineralization rates and the fate of polymer-derived carbon in soil remain poorly understood. We incubated UV-aged 13C-labeled polyethylene in…

Polyamide and polyvinyl chloride microplastics induce cytotoxicity and cytokine release in primary normal human bronchial epithelial cells
Abstract Our daily and continuous exposure to airborne micro- and nanoplastics (MNPs) together with the limited information on their potential hazards, warrants the need for more information on MNP-toxicity. In this study, we investigated the effects of diverse size ranges of amorphous MNPs from…
