Microplastics (MPs) have emerged as widespread environmental pollutants, causing significant threats to aquatic ecosystems and organisms.This review examines the toxic effects of MPs on fishes, with a focus neurobehavioural, physiological, reproductive impacts, well underlying mechanisms toxicity.Evidence indicates that induce range neurobehavioural abnormalities in affecting social interactions cognitive functions.Altered neurotransmitter levels are identified key mechanism driving behavioural alterations following MP exposure.Physiological fishes exposed also reported, including neurotoxicity, immunotoxicity, oxidative stress.These physiological disruptions can compromise individual health organisms.Furthermore, linked exposure discussed, particular emphasis endocrine signaling pathways.These impair success fish species, impacting population numbers.Here we explore critical role mediating after MPs, focusing primarily hypothalamic-pituitary-gonadal axis.Our highlights urgent need for interdisciplinary research efforts aimed at elucidating full extent toxicity its implications ecosystems.Lastly, identify knowledge gaps future research, investigations into transgenerational if any, quantifying synergetic/antagonistic other pollutants.This expanded regarding potential risks wildlife is expected aid policymakers developing mitigation strategies protect species.

Global environmental contamination by microplastics (MPs) is a growing problem with potential One Health impacts. The presence of MPs in vital organs, such as the heart, particular concern, but knowledge still limited. goal present pilot study was to investigate heart wild specimens three commercial fish species (Merluccius merluccius, Sardina pilchardus, and Trisopterus luscus) from North East Atlantic Ocean. Heart samples 154 were analysed for MP content (one sample per fish). A total 44 recovered species. had varied chemical composition (5 polymers), shapes (4) colours (5). Differences profile among observed (p ≤ 0.05). Thirty (19%) their hearts, mean (±SD) concentration 0.286 ± 0.644 MPs/fish. S. pilchardus highest There no significant > 0.05) differences between M. merluccius T. luscus. These findings different biological ecological traits together literature data suggest that likely disseminated phenomenon. Therefore, further research on cardiovascular system its health effects very much needed.
