Research Progress on Ecotoxicological Effects of Micro-Plastics Loaded Pollutants
Summary
This Chinese review summarizes the ecotoxicological effects of microplastics loaded with chemical pollutants on various organisms, covering how plastic particles adsorb and then transfer contaminants into digestive, respiratory, and immune systems. The combined chemical and physical effects of microplastics make them more hazardous than either the plastic particles or the chemicals alone.
The origin of microplastics and the effects of ecotoxicological effects of microplastics on organisms were summarized in this paper. Microplastics can directly affect the environment, such as being ingested directly by organisms. Because microplastics are small in size, they can be eaten by organisms by mistake, so they can inhibit the digestive system, respiratory system, immune system, reproductive system and genetic level of organisms. Microplastics will gradually release the chemicals added in the production process, these chemicals have toxic effect on the environment. When the environmental factors change, the additives contained in the microplastics components will be degraded and released, which will have toxic effect on the environment. Microplastics, as carriers, can carry pollutants, which together with microplastics can cause complex pollution to the environment. Because of the physical properties of microplastics, it is easy to load various pollutants on their surfaces. This will result in a deeper level of complex pollution to organisms and the environment. The ecotoxicological effects of microplastics loaded pollutants on the environment are more complicated, so we should pay more attention to the ecological toxicological effects of micro-plastics loaded pollutants.

The impact of microplastic pollution on ecological environment: a review
This review examines the broad ecological impact of microplastic pollution, focusing on how the strong adsorption capacity of microplastic surfaces allows them to carry persistent organic pollutants through the environment. Researchers found that the combined effects of microplastics and adsorbed chemicals increase toxicity to organisms across different levels of the food chain. The study calls for more research into the long-term ecological consequences of microplastic pollution and its synergistic effects with other contaminants.
A review on the combined toxicological effects of microplastics and their attached pollutants
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.
Ecotoxic effects of microplastics and contaminated microplastics – Emerging evidence and perspective
This review examined the ecotoxic effects of microplastics alone and when contaminated with other environmental pollutants. Researchers analyzed how microplastics' small size, surface properties, and hydrophobicity contribute to their environmental persistence and tendency to bind other contaminants. The study suggests that contaminated microplastics may pose greater ecological risks than pristine particles due to combined toxic effects.
Environmental processes and ecological effects of microplastics in the ocean
This Chinese review examines the environmental processes and ecological effects of microplastics in ocean environments, covering how plastics degrade, distribute, and interact with marine organisms. It discusses both physical and chemical toxicity mechanisms and the potential for microplastics to transfer up the food chain.
Microplastic in marine organism: Environmental and toxicological effects
This review examined microplastics as a complex mixture of polymers, additives, and adsorbed environmental contaminants, and assessed their toxicological effects on marine organisms from ingestion and internal distribution. The authors emphasize that microplastic harm comes not only from the plastic itself but from the chemical cocktail it carries, and review the growing evidence for food web transfer.
