ABSTRACT Microplastic (MP) pollution in the Ganga River, a vital waterway sustaining millions, has become significant environmental and public health concern. This review employed systematic approach to examine MP utilizing comprehensive database search across Scopus, PubMed, SpringerLink. discusses multifaceted pathways through which MPs enter propagate within river ecosystem. Key sources include urban industrial wastewater discharge, agricultural runoff laden with plastic mulch contaminated fertilizers, inadequate solid waste management leading litter illegal dumping. Atmospheric deposition also plays role transporting from centers river. Riverine dynamics, influenced by natural flow sediment processes, facilitate downstream transport of these pollutants. The cultural religious significance contributes ritual practices mass gatherings. Ecologically, pose severe threats, affecting aquatic organisms ingestion bioaccumulation toxic substances, thereby disrupting biodiversity food chains. Socio-economically, this jeopardizes livelihoods communities reliant on Addressing contamination demands mitigation strategies. Effective solutions must integrate scientific understanding robust safeguard ecological socio-economic integrity River.

Microplastic contamination is a challenge in aquatic systems. Among these, floodplains exhibit their cyclical hydrological patterns with substantial fluctuations water levels caused by annual floods or discharges from rivers into lakes. The influence of level fluctuation on microplastics within complex floodplain systems has received limited attention existing studies. This study employs data and physics-based hydrodynamic model to assess the effects transport redistribution Poyang Lake 2018 2025. High spatiotemporal distribution variability microplastic concentrations was found flood drought periods. Furthermore, residence rate assessed based concentration variations computational time. A gradual drop average discharge at outlet Lake. are more likely drain Yangtze River high water-level period.
