A broad review of ecotoxicological studies found that micro- and nanoplastics cause physical harm, oxidative stress, endocrine disruption, and reproductive impairment across a wide range of terrestrial and aquatic organisms, with nanoplastics generally exhibiting greater toxicity due to their smaller size and greater bioavailability.
A comprehensive review of the impact of microplastics on aquatic organisms: From ingestion to ecological consequences
This comprehensive review assessed the impacts of microplastics on diverse aquatic organisms—including fish, marine mammals, mollusks, crustaceans, and microorganisms—from ingestion through ecological-level consequences. The authors found that microplastics cause physical injury, oxidative stress, endocrine disruption, and behavioral changes across taxa, with downstream effects on food web structure and ecosystem function.
Impact of Nanoplastics on Marine Life: A Review
This review summarizes current knowledge about the effects of nanoplastics on marine organisms, including impacts on feeding, reproduction, growth, and cellular-level toxicity. Evidence indicates that nanoplastics can be more harmful than larger microplastics due to their ability to cross biological barriers and accumulate in tissues, though more research is needed on real-world exposure levels.

This review examines the effects of micro- and nanoplastics on marine environments and human health, covering sources, environmental fate, and biological impacts. Researchers summarize evidence that these particles can cause oxidative stress, inflammation, and disruption of gut microbiota in exposed organisms. The study highlights that while the full extent of health risks remains uncertain, the pervasive presence of plastic particles in food, water, and air makes continued research a public health priority.
Review of mechanisms and impacts of nanoplastic toxicity in aquatic organisms and potential impacts on human health
This review summarizes what we know about how nanoplastics (tiny plastic particles smaller than 1 micrometer) affect fish, shellfish, and other aquatic life, and what that could mean for people who eat seafood. Studies show nanoplastics build up in marine organisms and move up the food chain, causing oxidative stress, DNA damage, and inflammation along the way. Major gaps remain in understanding the long-term health effects of the low levels of nanoplastics people are likely exposed to through their diet.
