ClearThe Impact of Micro- and Nanoplastics on Aquatic Organisms: Mechanisms of Oxidative Stress and Implications for Human Health—A Review
This review examines how microplastics and nanoplastics cause oxidative stress, a harmful chemical imbalance, in aquatic organisms from plankton to fish. These tiny plastics accumulate in the food chain and may reach humans through seafood consumption. While the evidence of harm in aquatic species is growing, more research is needed to fully understand the implications for human health.
Unraveling the ecotoxicological effects of micro and nano-plastics on aquatic organisms and human health
This review summarizes the growing body of evidence on how micro- and nanoplastics affect aquatic organisms and, through the food chain, potentially human health. The tiny plastic particles absorb toxic pollutants and pathogens from the water, acting as carriers that deliver these harmful substances into the bodies of fish, shellfish, and other organisms. The review highlights that both direct plastic toxicity and indirect chemical exposure through contaminated seafood pose risks to human consumers.

Biological Effects of Microplastics: A Review.
Researchers reviewed how microplastics harm a wide range of living things, finding they cause physical damage, inflammation, oxidative stress, and reproductive problems in aquatic animals, while also carrying toxic chemicals and dangerous bacteria into organisms. Major gaps remain in understanding the effects of long-term low-dose exposure and the risks posed by even tinier nanoplastics.
Ecotoxicological Impacts of Micro and Nanoplastics on Marine Fauna
This review examines the ecotoxicological impacts of micro- and nanoplastics on marine fauna, detailing how these particles enter food chains through ingestion, accumulate across trophic levels, and cause physical and chemical harm including oxidative stress, inflammation, reproductive disruption, and mortality. The authors highlight the compounding threat when plastics act as vectors for adsorbed pollutants.
Plastic contamination of the food chain: A threat to human health?
This review examines how microplastics and nanoplastics enter the human food chain through shellfish, inhalation, and other routes, and assesses what is known about their toxicity. The authors conclude that while larger microplastics appear to have low absorption and toxicity, nanoplastics may accumulate in tissues and potentially affect the nervous and reproductive systems, though effects in humans remain unproven.
A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.
An overview of the effects of nanoplastics on marine organisms
This review summarizes current knowledge about how nanoplastics affect marine organisms, from plankton to fish.
