Combined Molecular Toxicity Mechanism of Microplastics Mixtures
AI summary Read the abstract
This review examines how microplastics interact with other environmental pollutants like heavy metals, pesticides, and pharmaceuticals, altering how toxic those substances behave. The study explores the molecular mechanisms behind these combined toxicity effects, which matter because in real-world environments, organisms are rarely exposed to microplastics in isolation.
In recent decades, the issue of microplastic pollution in the environment has garnered global attention due to its significant impacts. Microplastics, characterized by a large specific surface area and strong fluidity, readily interact with various pollutants in the environment, thereby altering the environmental behavior of these pollutants. Understanding the adsorption processes and mechanisms through which microplastics interact with diverse pollutants is essential for comprehending the environmental implications of pollutant adsorption onto microplastics and the associated changes in toxic effects. This chapter investigated the impact of microplastic mixtures on molecular toxicity mechanisms. By considering the varying toxicological effects of different pollutants, we explored the combined toxicity mechanisms of heavy metals, persistent organic pollutants, pathogens, engineered nanoparticles, and other pollutants with microplastics. Additionally, we detailed classical and emerging toxicological models, including various cells and in vivo models of model organisms. The findings will contribute to a comprehensive understanding of the environmental and biological implications of microplastic pollution, offering insights for developing effective strategies to mitigate its adverse effects. Simultaneously, these findings can serve as valuable references for readers during the process of model organism selection and model establishment.

A review on the combined toxicological effects of microplastics and their attached pollutants
AI summary Read the abstract
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including heavy metals and persistent organic chemicals — and how these combinations produce toxic effects in organisms that are more severe than either contaminant alone. The findings highlight a complex, layered toxicity problem that affects microbes, invertebrates, and vertebrates across marine and terrestrial environments.
Microplastic interactions with co-existing pollutants in water environments: Synergistic or antagonistic roles on their removal through current remediation technologies
AI summary Read the abstract
This review examines how microplastics interact with other pollutants like heavy metals, pesticides, and pharmaceuticals in water, often making each contaminant harder to remove during treatment. The interactions between microplastics and co-existing pollutants can produce unpredictable combined toxic effects that are worse than either pollutant alone. Understanding these interactions is important because real-world water contamination involves mixtures, not single pollutants, and current treatment methods may not adequately address these combinations.
Microplastics and environmental pollutants: Key interaction and toxicology in aquatic and soil environments
AI summary Read the abstract
This review tracks how microplastics move through soil, water, and air ecosystems, acting as carriers for other pollutants like pesticides and heavy metals. When microplastics absorb these toxins, the combined effect on organisms can be worse than either pollutant alone. The paper highlights the need for better understanding of how these pollutant combinations affect ecosystems and ultimately human health through contaminated food and water.
