Chemical reactivity theory to analyze possible toxicity of microplastics: Polyethylene and polyester as examples

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(3), P. e0285515 - e0285515

Published: March 6, 2024

Micro- and nanoplastics are widespread throughout the world. In particular, polyethylene (PE) terephthalate or polyester (PET) two of most common polymers, used as plastic bags textiles. To analyze toxicity these oligomers with different numbers units were models. The use polymeric templates has been previously success. We started monomer continued until chain length was greater than nm. According to results quantum chemistry, PET is a better oxidant PE, since it electron acceptor. Additionally, negatively charged oxygen atoms can promote stronger interactions PE other molecules. found that forms stable complexes dissociate guanine-cytosine nucleobase pair. This could affect DNA replication. These preliminary theoretical may help elucidate potential harm micro- nanoplastics.

Progress in selecting marine bioindicators for nanoplastics ecological risk assessment

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110836 - 110836

Published: Aug. 20, 2023

Nanoplastic (<1 µm) pollution in the marine environment is a cause of growing concern due to current difficulties measuring their occurrence abiotic and biotic matrices, with consequent uncertainties on ecological risk for natural communities associated ecosystem services. Most investigations dealing nano-ecotoxicity have been conducted bench-scale by examining effects single model species under short-term exposure conditions at high concentrations (>50 mgL−1). Both negligible impacts detrimental effects, although poorly descriptive real environmental scenarios, documented different trophic levels functionalities. Polystyrene nanospheres (<100 nm) are far most tested as proxy nanoplastics, even though nanoplastics composed other polymers shapes (i.e., irregular fibers) has reported seawater column sediments. Limited information bioaccumulation hamper selection key bioindicator following various criteria target, highly sensitive, endangered, etc) monitoring assessment (ERA) purposes. A holistic approach thus required starting from setting environmentally relevant coupled chronic exposure, selecting bioindicators including those having role processes, functions services, also human consumption (shellfish seafood). The present mini-review aims provide framework best nanoplastic along knowledge sources, circulation behavior temperate polar environments potential compartments/species more support ERA. Less investigated niches habitats, which should deserve attention future studies, identified.

Nanoplastic-Induced Developmental Toxicity in Ascidians: Comparative Analysis of Chorionated and Dechorionated Phallusia mammillata Embryos

Journal of Xenobiotics, Journal Year: 2025, Volume and Issue: 15(1), P. 10 - 10

Published: Jan. 10, 2025

Nanoplastics pose a growing threat to marine ecosystems, particularly affecting the early developmental stages of organisms. This study investigates effects amino-modified polystyrene nanoparticles (PS-NH2, 50 nm) on embryonic development Phallusia mammillata, model ascidian species. Both chorionated and dechorionated embryos were exposed increasing concentrations PS-NH2 so morphological alterations could be assessed with high-content analysis phenotypes genotoxicity. induced same in both embryos, being more sensitive (EC50 = 3.0 μg mL-1) than ones 6.26 mL-1). Interestingly, results from showed two concentration-dependent mechanisms action: (i) at near EC50, neurodevelopmental abnormalities resembling by exposure known endocrine disruptors (EDs) observed, (ii) higher (15 mL-1 7.5 for respectively), nonspecific toxicity was evident, likely due general oxidative stress. The resulting treatment not related DNA damage, as revealed genotoxicity assay performed neurula embryos. Our data suggest that PS-NH2-induced is primarily mediated through stress, probably triggered interactions between positive charges PS NPs negative cell membranes. lack protective chorion further exacerbated these effects, highlighting its role mitigating/protecting against NP-induced damage.

Nanotechnologies have rapidly grown, and they are considered the new industrial revolution. However, augmented production wide applications of engineered nanomaterials (ENMs) nanoparticles (NPs) inevitably lead to environmental exposure with consequences on human health. Engineered nanomaterial nanoparticle (ENM/P) effects humans environment complex largely depend interplay between their peculiar properties such as size, shape, coating, surface charge, degree agglomeration or aggregation those receiving media/body. These rebounds ENM/P safety newly developed concepts by design gaining importance in field sustainable nanotechnologies. This article aims review critical characteristics ENM/Ps that need be addressed safe process develop ablility reduce/minimize any potential toxicological risks for living beings associated exposure. Specifically, we focused silver (AgNPs) due an increasing number nanoproducts containing AgNPs, well knowledge about these (NMs) effects. We ecotoxicological documented freshwater marine species demonstrate relationship biological outcomes terms safety.
