Impact of ingested microplastics on phenotypic traits and biochemical parameters in Nile tilapia (Oreochromis niloticus) juvenile
AI summary Read the abstract
Juvenile Nile tilapia exposed to microplastics showed significantly lower survival rates, reduced body weight, smaller eye diameter, elevated superoxide dismutase activity, and reduced catalase activity compared to controls, indicating physiological stress and impaired antioxidant defense. These dose-response effects on a widely farmed species provide direct evidence that microplastic ingestion compromises fish growth and survival, with implications for aquaculture productivity and the integrity of fish-based food systems.
Aging enhances the ecological toxicity of polyethylene microplastics to marine medaka larvae (Oryzias melastigma)
AI summary
Researchers found that UV- and Fenton-aged polyethylene microplastics caused greater harm to marine medaka larvae than virgin plastic, disrupting gut microbiota composition and altering microbial metabolic functions in ways that impaired growth and development, underscoring the need to assess weathered microplastics in ecological risk evaluations.
Micro/nanoplastics in Aquatic Ecosystems: An Integrated Review of Occurrence, Toxicological Implications, Case Studies, Methodologies, and Future Recommendations
AI summary Read the abstract
This integrated review covers the occurrence, toxicology, and detection of micro- and nanoplastics across freshwater, marine, and estuarine ecosystems, using case studies to illustrate biomagnification through aquatic food webs and the compounding risk from co-occurring chemical contaminants. The review calls for stronger international collaboration and policy frameworks grounded in scientific evidence, recognizing that the pervasive nature of micro- and nanoplastics in aquatic systems poses escalating risks to both ecosystem integrity and human health.
Microplastic Toxicity in Aquatic Organisms and Aquatic Ecosystems: a Review
AI summary Read the abstract
Researchers reviewed how microplastics move through aquatic food webs, finding evidence that these particles accumulate across trophic levels, but noted that most toxicity studies are conducted in labs rather than real ecosystems, leaving major gaps in understanding the true ecological and human health risks.
The occurrence of microplastic in aquatic environment and toxic effects for organisms
AI summary Read the abstract
"This review synthesized global research on microplastic occurrence in aquatic environments, finding that microplastics are widespread across all water bodies and can trigger inflammation, impair reproduction, and carry co-contaminants such as heavy metals, organic pollutants, and additives into organisms via bioaccumulation. The evidence underscores the need for stricter plastic emissions standards and improved water management, as aquatic microplastic pollution directly cascades into human dietary exposure through seafood and drinking water."
