The Toxicity of (Nano)Microplastics on C. elegans and Its Mechanisms
AI summary Read the abstract
Researchers reviewed the toxicological effects of micro- and nanoplastics on the model organism Caenorhabditis elegans, finding that these particles cause oxidative stress, reproductive impairment, developmental delays, and neurological dysfunction, with nanoplastics generally more toxic than microplastics due to their greater cellular penetration.
Microplastics (MPs) and nanoplastics (NPs) are respectively defined as plastic debris with sizes of <5 mm and <100 nm. In recent years, (nano)microplastics (N/MPs) have been widely detected in air, water, soil, and other environmental matrices. Despite...

Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.
Microplastics and nanoplastics in human health: a comprehensive review of exposure pathways, cellular mechanisms, and toxicological implications
AI summary Read the abstract
Researchers reviewed human exposure pathways to microplastics and nanoplastics through seafood, salt, drinking water, inhalation, and skin contact, examining how these particles cross biological barriers to reach organs and trigger oxidative stress, inflammation, and endocrine disruption with poorly understood long-term consequences.
A Critical Review on Biological Impacts, Ecotoxicity, and Health Risks Associated with Microplastics
AI summary Read the abstract
Researchers review the biological impacts and ecotoxicity of microplastics across ecosystems, documenting how these persistent particles transfer through trophic levels, disrupt feeding behavior, obstruct digestive tracts, impair respiratory and reproductive systems in aquatic species, and have been detected in human placentas, while calling for stronger regulations to limit environmental accumulation.
