Microplastic pollutants in lakes can introduce a series of ecological and environmental problems, mapping the sources microplastics is key to solving lake microplastic pollution. In this study, atmospheric samples collected from 6 sampling sites Wuliangsuhai Lake March June 2021 were analyzed, deposition fluxes measured, simulated using HYSPLIT model. The results showed that average flux was (3371 ± 1423) n/d·m2 ; at order ML-3 > ML-5 ML-6 ML-2 ML-4 ML-1; shapes included fibrous, fragmented, lumpy, blocks; colors transparent, black, blue, red, green, yellow; species polypropylene, polyethylene, rayon, polyethylene terephthalate, polystyrene, natural fibers. According basic characteristics backward trajectories, primarily attributable transportation external large cities, with small portion surrounding local environment. study provide theoretical basis for other inland as well prevention control pollution, which great significance traceability pollutants.

The quality of water in urban parks is closely related to people's daily lives, but the pollution caused by microplastics park and sediments has not been comprehensively studied. Therefore, eight typical area Changsha, China, were selected, Raman spectroscopy was used explore spatial distributions compositions sediments, analyze their influencing factors, evaluate environmental risks. results showed that abundances surface all ranged from 150 525 n L
