| 英文摘要 | Microplastic pollution in freshwater lakes poses significant threats to ecosystems and human health, particularly at the water-sediment interface where sources and transport processes converge. The present study investigated microplastic pollution in Baiyangdian Lake, a representative freshwater lake in the North China Plain. Baiyangdian Lake, the largest and most representative shallow lake in the North China Plain, lies at the core of the newly established Xiong'an New Area, where rapid urban expansion, wastewater discharge, agricultural runoff, and aquaculture activities intensify plastic inputs. To evaluate sources, transport, and risks, microplastics were sampled from overlying water and sediments at ten sites during the dry (October 2021) and wet (August 2022) seasons. Concentrations reached 500-16,000 n center dot m-3 in water and 167-5000 n center dot kg-1 in sediments during the dry season, with lower averages in the wet season (355 n center dot m-3; 2610 n center dot kg-1). Films dominated, indicating mulch film, packaging, and sewage as key sources. Seasonal hydrodynamics controlled vertical exchange: smaller particles (<= 100 mu m) remained suspended in water, while larger ones accumulated in sediments, especially under reduced flows in the dry season. Ecological risk assessment showed higher risks in the dry season, with the polymer hazard index classifying sediments as high risk. The present study elucidates microplastic pollution mechanisms in a representative lacustrine system, providing critical insights for development of targeted mitigation strategies at the water-sediment interface and informing ecosystem-scale management approaches applicable to comparable freshwater basins. |
