Detection of Various Microplastics in Human Stool: A Prospective Case Series.

TL;DR: In this article, microplastics (0.5 µm) were administered orally to C57BL/6J mice for 4 consecutive weeks at the rate of 0.5 mg/day, and the secretion level of inflammatory cytokines and associated signaling pathway were investigated using quantitative real-time polymerase chain reaction and western blot.

TL;DR: This review synthesizes existing research on microplastics and nanoplastics in terrestrial ecosystems, examining their uptake, translocation, trophic transfer, ecotoxicology, and human health risks, highlighting knowledge gaps and recommending avenues for further investigation.

TL;DR: In this article , the authors measured abundances of atmospheric-deposited microplastics of up to 105 items m-2 d-1 in dining/drinking venues, with 90% smaller than 100 µm and a dominance of amorphous fragments rather than fibers.

TL;DR: In this article, the authors analyzed 23 brands of table salts from 8 African countries for microplastics using microscopic/spectroscopic techniques and found that South Africa showed the highest microplastic concentration (0.33 ± 1.32 particles/kg), Nigeria, Cameroun, and Ghana (0 − 0.33± 0.38 particles/ kg each); characterized as polyvinyl acetate, polypropylene, and polyethylene.

TL;DR: This work critically discusses the advantages and disadvantages of a unified terminology, proposes a definition and categorization framework, and highlights areas of uncertainty on how to define and categorize plastic debris.

TL;DR: Focusing on the American diet, the number of microplastic particles in commonly consumed foods in relation to their recommended daily intake is evaluated and it is estimated that annual microplastics consumption ranges from 39000 to 52000 particles depending on age and sex.

TL;DR: The presence of marine microplastics in seafood could pose a threat to food safety, however, due to the complexity of estimating microplastic toxicity, estimations of the potential risks for human health posed by microplastically in food stuffs is not (yet) possible.

TL;DR: The pervasive microplastic contamination as a potential agent of global change in terrestrial systems is introduced, the physical and chemical nature of the respective observed effects are highlighted, and the broad toxicity of nanoplastics derived from plastic breakdown is discussed.
