Summary

This review summarizes the widespread presence of microplastics across marine ecosystems, noting their accumulation in fish tissues including digestive tracts and gills. Sources range from synthetic textiles and packaging to personal care products, and advanced detection methods have now confirmed microplastics in human tissues as well. The paper underscores the need for comprehensive strategies to reduce microplastic pollution for the protection of both marine life and human health.

Body Systems

Microplastics, primarily derived from plastic waste, are pervasive environmental pollutants found across aquatic and terrestrial ecosystems. This review investigates microplastics’ presence, distribution, and impacts in marine ecosystems, with a particular focus on fish species. Research indicates that microplastics are present in various anatomical parts of fish, including the gastrointestinal tracts and gills, with significant implications for marine biodiversity and human health through seafood consumption. The review also highlights the sources of microplastics, such as synthetic textiles, packaging, and personal care products, and explores the pathways through which these particles enter marine environments. Advanced detection techniques have identified microplastics in human tissues, underscoring the urgency of addressing this environmental threat. Comprehensive strategies are essential to mitigate microplastic pollution and protect both marine life and human health.
