The environmental effects of microplastics on aquatic ecosystems
AI summary Read the abstract
Researchers reviewed the growing body of evidence on how microplastics harm aquatic ecosystems, finding that long-term exposure damages organisms at multiple levels — from delivering toxic chemicals to disrupting reproduction — and calling for urgent action to reduce plastic leakage into waterways.
Contamination of aquatic ecosystems by plastics under 5 mm in size, which are classified as microplastics (MPs), is becoming increasingly serious, and research on the ecotoxicity of MPs is needed. In this study, we aimed to present solutions to the problem of MPs through a review of the current state of research on the definition of MPs, usage, leakage, toxicity, and domestic and overseas circulation of plastics. Long-term exposure to MPs results in ecotoxicity. MPs not only deliver chemical substances within organisms, but also act as mediators for chemicals or other contaminants in aquatic environments. Co-exposure to MPs and chemical contaminants has been reported to increase toxicity in several organisms.

Environmental perspectives of microplastic pollution in the aquatic environment: a review
AI summary Read the abstract
Researchers reviewed how microplastics spread through freshwater and marine environments worldwide, finding they accumulate in sediments, absorb toxic chemicals, and create surfaces where antibiotic-resistant and potentially pathogenic bacteria can thrive. This pollution threat reaches even Antarctica and the deep sea, posing risks throughout aquatic food webs.
Effects of plastics and microplastics on aquatic organisms and human health
AI summary Read the abstract
This review paper pulls together existing research showing that tiny plastic particles called microplastics are ending up in fish, mussels, shrimp, and other seafood we eat. Because these creatures absorb microplastics from polluted water, the plastic can travel up the food chain and onto our plates, meaning our growing use of plastic may be quietly working its way into our diets. The authors call for more public awareness and action to reduce plastic pollution before its full health effects on people are better understood.
