Microplastic and nanoplastic exposure and toxicity across marine taxa

Micro- and Nanoplastics—Impact on Marine Vertebrates and Invertebrates

AI summary · Read the abstract

Researchers reviewed the impact of micro- and nanoplastics (MNPs) on marine vertebrates and invertebrates, finding widespread evidence of ingestion, tissue accumulation, and physiological harm across species, with implications for marine ecosystem health and human consumers of seafood.

Ecotoxicity of Microplastic Pollutants to Marine Organisms: a Systematic Review

AI summary · Read the abstract

Researchers conducted a systematic quantitative literature review of microplastic ecotoxicity in marine organisms, finding that polyethylene, polypropylene, and polystyrene particles (1–100 µm) are most commonly ingested and cause mortality, reproductive impairment, genotoxicity, and behavioral effects across a wide range of species.

Micro- and Nanoplastics Impact on Food Sources of Marine Origin

AI summary · Read the abstract

Researchers reviewed how micro- and nanoplastics contaminate marine-sourced foods including fish, shellfish, and seaweed, raising concerns about human dietary exposure. With billions of metric tons of plastic produced since 1950, ocean food sources represent a significant and growing pathway for plastic particles entering the human body.

Toxicity and Possibility of Microplastic Exposure While Living

Exploring the detrimental effects of nanoplastics on ecosystems and human health

AI summary · Read the abstract

Tiny plastic particles called nanoplastics, so small they can pass through cell walls, have been found everywhere from polar ice to human tissue, and this review pulls together existing research on how they might harm both the environment and our bodies. While scientists are still working out the exact health risks, the concern is that these particles could build up in our organs over time, which is why researchers are calling for more study and better plastic waste management. The takeaway: plastic pollution isn't just an environmental issue anymore, it's becoming a personal health question too.
