Genotoxic and neurotoxic potential of intracellular nanoplastics: A review

Journal of Applied Toxicology, Journal Year: 2024, Volume and Issue: 44(11), P. 1657 - 1678

Abstract Plastic waste comprises polymers of different chemicals that disintegrate into nanoplastic particles (NPLs) 1–100‐nm size, thereby littering the environment and posing a threat to wildlife human health. Research on NPL contamination has up now focused ecotoxicology effects pollution rather than health risks. This review aimed speculate about possible properties carcinogenic neurotoxic as pollutants. Given their low‐dimensional size high surface ratio, NPLs can easily penetrate biological membranes cause functional structural damage in cells. Once inside cell, interrupt autophagy flux cellular debris, alter proteostasis, provoke mitochondrial dysfunctions, induce endoplasmic reticulum stress. Harmful metabolic processes induced by include oxidative stress (OS), ROS generation, pro‐inflammatory reactions. Depending cell cycle status, may direct DNA damage, tumorigenesis, lately carcinogenesis tissues with self‐renewal capabilities like epithelia. In cells able live longest neurons, could trigger neurodegeneration promoting toxic proteinaceous aggregates, OS, chronic inflammation. genotoxicity neurotoxicity are discussed based gathered evidence, when available, within context intracellular uptake these newcomer nanoparticles. summary, this explains how risk evaluation for benefit from accurately monitoring toxicokinetics toxicodynamics at resolution level.

What can we learn from biodegradation of natural polymers for regulation?

Environmental Sciences Europe, Journal Year: 2023, Volume and Issue: 35(1)

Published: June 28, 2023

Abstract Synthetic polymers are chemicals of emerging concern for the environment, which is mainly attributed to their persistence in environmental compartments. On other hand, exist nature as well. They regarded no environment. The present article focusses on fate natural and implications assessment synthetic polymers. Natural vary widely structure, function, properties. Crystallinity, wettability surface area important influencing factors (bio)degradation kinetics. Chemical enzymatic hydrolysis most process degradation polymers, particulate material takes place either by bulk or erosion. Some degraded rapidly, but cases, very long until complete mineralization. These differences biodegradability a result evolution they have fulfil specific functions might require certain persistency. Consequently, many would be considered persistent (P vP) based available studies using standard approach. At same time, environment good reasons. analysis emphasizes that mineralization alone not resilient endpoint This needs recognized when assessing existing P/vP criteria For such it establish meaningful endpoints polymer enable an adequate weight-of-evidence

Incognito forms of polyethylene small micro and nanoplastics in solvents: Changes in molecular vibrations

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 968, P. 178923 - 178923

Plastic particles in the range of 1 nm to μm diameter are nano pollutants all environments, ubiquitous throughout air, waters and living organisms. The formation nanoplastics (NP) occurs different ways that include material abrasion, light exposure even from normal use plastic materials. In solvents, NP small microplastics (< 10 diameter) differ larger they can mix suspend, similar other colloidal sized particles. this study, we used mixing conditions our novel solubilization method generate polyethylene (PE) microplastic nanoplastic solutions (sM&NP), both water common organic solvents. sM&NP were examined using Raman spectroscopy microscopy, transmission electron microscopy (TEM) particle size analysis dynamic scattering (DLS) methods. data showed notable spectral changes compared solid PE, which indicates significant molecular morphological PE polymer when it is part these or suspensions. for signified a loss crystallinity, while aqueous suggest greater reorganization structure. These structural supported by TEM images appeared mostly amorphous with varying thickness. Importantly, changed spectra likely render them more difficult detect particularly real-world systems. findings indicate solubilized routinely modified solvent exposure, thereby interact differently materials, environments.

Micro(nano)plastics: A review on their interactions with pharmaceuticals and pesticides

TrAC Trends in Analytical Chemistry, Journal Year: 2023, Volume and Issue: 169, P. 117307 - 117307

Published: Oct. 4, 2023

This review provides an overview of the current knowledge addressing interactions between micro(nano)plastics (MNPs) and pharmaceuticals or pesticides, highlights main findings, outlines research perspectives for future investigations. The available studies demonstrated that MNPs can act as pollutant carriers. reviewed literature reveals influence toxicity pesticides in various environmental compartments, modulating either through antagonistic synergistic interactions. have been shown to mostly confer protective effects against antibiotics, while exacerbating toxic certain pesticides. To ensure a more comprehensive understanding pharmaceuticals/pesticides, should focus on several key aspects include environmentally relevant scenarios (e.g., concentrations, long-term exposures), elucidation underlying mechanisms action at molecular cellular levels different species also considering climate change scenarios.
