Shock Wave-Induced Degradation of Polyethylene and Polystyrene: A Reactive Molecular Dynamics Study on Nanoplastic Transformation in Aqueous Environments

Molecules
Degradation of polyethylene and polystyrene was studied theoretically using reactive molecular dynamics based on the ReaxFF force field. The degradation reactions were carried out on nanoparticles (approximately 2 nm in diameter) composed of ideal low ...

Peatlands as geo-archives for atmospheric micro- and nano-plastics: a perspective review

Frontiers in Earth Science
Since commercial manufacture of plastics started around 1950, plastics have grown more and more important to human society. The ubiquity of plastic particles in the environment and Inefficient waste management have led to the presence of tiny plastic ...

095 | Nanoplastic as modulators of human immune responses: effect on nk and t cells

Journal of Biological Research
Micro- and nanoplastics are increasingly recognized as emerging environmental contaminants with potential consequences for human health. Although their widespread presence has been documented across multiple environmental matrices, evidence of their ...

The selective permeability of mucin hydrogels is modulated by nanoplastic contaminations [PDF]

The mucosa lining all wet epithelial tissues in our body is mainly established by mucin glycoproteins and constitutes the first line of defense that controls the selective uptake of substances into sub-mucosal tissues.

The Need for Properly Designed Synthesized Micro- and Nanoplastics with Core–Shell Structure

Microplastics
While there are a number of available reference and testing materials for micro- and nanoplastic (MNP) studies in toxicology, they are not well-characterized and do not cover all major polymer types that may potentially pollute the environment.

Ultrastructural and Proteomic Analyses Revealed the Mechanism by Which Foliar Spraying of Se Nanoparticles Alleviated the Toxicity of Microplastics in Pistia stratiotes L.

Toxics
The uptake and accumulation of nanoplastics by plants have emerged as a major research focus. Exogenous selenium nanoparticles (SeNPs) are widely used to mitigate the toxicity of abiotic stresses, such as nanoplastics (NPs) and polyethylene (PE—NPs ...

Nanoplastic affects growth of S. obliquus and reproduction of D. magna

, 2014
The amount of nano- and microplastic in the aquatic environment rises due to the industrial production of plastic and the degradation of plastic into smaller particles. Concerns have been raised about their incorporation into food webs.

Investigating microplastics and nanoplastics released from food bag ziplock using SEM and Raman imaging

Nano Express
Microplastic contamination is a concern in our daily lives, such as being released from self-sealing ziplock (sliderless zipper) plastic bags that are commonly used for food storage. That is because during the closure and opening process, due to friction
