Occurrence, distribution, and ecological risk of microplastics in Chinese surface waters: a systematic review and multi-model assessment

Low abundance but high microplastic toxicity and potential ecological risks in a drinking-water source.

Microplastics (MPs) in drinking-water sources pose potential health risks, yet their ecological threats under low-intensity anthropogenic activities remain poorly understood. To address this, this study focused on the Miyun Reservoir (Beijing's primary drinking-water source), and systematically collected surface water...

Microplastics Contamination and Ecological Risk Assessment in Natural and Afforested Mangrove Stands of Bahrain: Abundance, Polymer Composition, and Onshore–Offshore Variability

Mangrove ecosystems are ecologically important coastal habitats, yet data on microplastic (MP) contamination along Bahrain’s coasts remain scarce. This study investigated the abundance, characteristics, and ecological risks of MPs in sediments from four mangrove sites (12 stations) collected in 2025. MPs were extracted...

Microplastics in the Qinghai–Tibet Plateau: Distribution Characteristics, Sources, and Migration Pathways

Microplastics (MPs), defined as plastic particles smaller than 5 mm in diameter, are an emerging class of environmental contaminants of global concern. As the “Water Tower of Asia” and a critical global ecological barrier, the environmental condition of the Qinghai–Tibet Plateau has a direct influence on the ecological...

Temporal Dynamics of Microplastic Pollution in the Meishe River: Decreasing Surface Water Abundance versus Increasing Sediment Accumulation

Influence of land uses on microplastic abundance and composition in surface waters and sediments of Sefidroud River, Iran

Occurrence and characterization of microplastics in freshwater surface waters: evidence from Lake Eğirdir (Türkiye)
