The aim is to elucidate how MPs affect aquatic organisms and ecosystems. The study analyzes the behavior of MPs in aquatic systems and their potential to harm aquatic biodiversity-ecosystem functioning. It explores pathways such as runoff and wastewater through which MPs enter aquatic systems. The study provides insights into the specific impacts of MP pollution on aquatic ecosystems, facilitating a better understanding of their consequences. By identifying pathways and potential risks, this text aims to contribute valuable knowledge to ongoing efforts to understand, manage, and mitigate the impact of MPs on aquatic environments. © (Publisher name) (publishing year) all right reserved.eninfo:eu-repo/semantics/closedAccessToxicity Mechanism, Exposure Pathways, and Environmental Risk Assessment of Microplastic PollutionBook PartN/AN/A5881
