ClearStudy of the toxicological effects of emerging contaminants on Daphnia similis associating polyethylene microplastics with the agrochemical imidacloprid.
Brazilian researchers tested the ecotoxicological effects of combining polyethylene microplastics with the insecticide imidacloprid on the freshwater crustacean Daphnia, finding combined exposures were more toxic than either pollutant alone. These results suggest that microplastics and pesticides together pose greater risks to aquatic organisms than studies of single pollutants indicate.

The study suggests that contaminated microplastics may pose greater ecological risks than pristine particles due to combined toxic effects.
Microplastics and associated emerging contaminants in the environment: Analysis, sorption mechanisms and effects of co-exposure
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including antibiotics, PFAS, and triclosan — absorbing them from surrounding water and potentially delivering higher doses to organisms that ingest the plastic, with combined toxicity effects that can be either amplified or reduced depending on the combination.
Fate of microplastics and emerging contaminants: Mechanisms of interactions, bioaccumulation and combined toxicity to aquatic organisms
This review summarizes how microplastics interact with other emerging contaminants in water, finding that microplastics can absorb pollutants at concentrations up to a million times higher than surrounding water and carry them into living organisms. The combined toxicity of microplastics plus these hitchhiking chemicals is often greater than either alone, and these pollutants can reach humans through the food chain.
Microplastics and PFAS as ubiquitous pollutants affect potencies of highly toxic chemicals in mixtures
Researchers investigated how ubiquitous pollutants like PFAS and microplastics affect the toxicity of other highly toxic chemicals when present together in mixtures. They found that even at non-toxic concentrations, PFAS and microplastics could alter the potency of co-occurring toxic compounds. The study highlights the importance of considering pollutant interactions in complex environmental mixtures rather than assessing chemicals in isolation.
Microplastics aggravate the bioaccumulation and toxicity of coexisting contaminants in aquatic organisms: A synergistic health hazard
Researchers conducted a quantitative meta-analysis of 870 endpoints from 40 studies to evaluate whether microplastics increase the bioaccumulation and toxicity of co-occurring contaminants in aquatic organisms. They found that microplastics significantly increased co-contaminant bioaccumulation by 31% and exacerbated toxicity by 18%, with effects manifesting as increased oxidative stress, endocrine disruption, and immunotoxicity. The study confirms that microplastics act as vectors that amplify the hazards of other environmental pollutants.
