Efectos Celulares De La Exposición a Micropartículas Plásticas En Organismos Acuáticos
Summary
This review examines cellular effects of microplastic and nanoplastic exposure in aquatic organisms, synthesizing laboratory evidence that plastics alone or combined with other toxicants cause membrane lysis, mitochondrial damage, reactive oxygen species generation, genotoxicity, and apoptosis.
Microplastics and nanoplastics are among the most widely distributed pollutants globally and currently concern humanity, mainly because of their durability and the adverse effects it shows in different organisms, both in terrestrial and aquatic environments. It has been shown in laboratory studies that plastics of various types, either simply or in combination with other toxic compounds or elements, elicit potentially harmful responses at the cellular level, such as cell membrane lysis, modulation of membrane receptors, changes in membrane potentials, alterations in permeability, mitochondrial damage, changes in metabolic activities, generation of reactive oxygen species, genotoxicity, DNA damage and apoptosis. However, our knowledge about the effects of microplastics concentrations in the natural environment needs to be improved.

Do microbial decomposers find micro- and nanoplastics to be harmful stressors in the aquatic environment? A systematic review of in vitro toxicological research
Researchers systematically reviewed in vitro studies on how bacteria and fungi respond to micro- and nanoplastics, finding that polystyrene particles and E. coli dominate the literature and that nanoplastic toxicity commonly disrupts antioxidative systems, gene expression, and cell membrane integrity in microbial decomposers.
Genotoxicity and Genomic Instability Induced by Micro- and Nanoplastics: A Comprehensive Multi-Taxa Mechanistic Review.
This review of existing research found that tiny plastic particles (microplastics and nanoplastics) can damage DNA in many different living things, from fish to human cells. The plastic particles cause this damage by creating harmful molecules called free radicals, disrupting the body's ability to repair DNA, and triggering inflammation. These findings suggest that the growing amount of plastic pollution in our environment could pose serious health risks to humans and wildlife.
Effects of Nanoplastics on Aquatic Organisms
This review summarizes how nanoplastics — plastic particles smaller than 1 micrometer — affect aquatic organisms, highlighting their ability to penetrate cell membranes, accumulate inside organisms, and cause oxidative stress and reproductive harm.
Synergistic effects of marine pollutants and microplastics on the destabilization of lipid bilayers
Researchers found that marine pollutants and microplastics act synergistically to destabilize lipid bilayers, suggesting that the combined presence of plastic particles and co-adsorbed chemicals may amplify cellular membrane damage beyond what either stressor causes alone.
