Microplastic (MP) pollution, an emerging global change factor, disturbs the ecosystem functioning. Inland wetlands, providing important services, might be sink for MPs. Understanding distribution, source, and fate of MPs in inland wetland ecosystems is a prerequisite developing effective management strategy. Here, different types including river wetland, constructed lake were selected to explore pollution patterns therein. Results showed that abundance soil ranges from 532 4309 items/kg. Transparent, fibers, polyethylene terephthalate most common color, shape, polymer type MPs, respectively. The this study did not significantly remove was one main sinks had accumulated large amounts In addition, MP characteristics cluster analyses aquaculture, agricultural cultivation, domestic waste sources area. occluded particulate organic carbon content related abundance. conclusion, reveals special river-constructed-lake which would help better understand distribution source wetlands have implications subsequent control ecological restoration wetlands.

Plastics play a crucial role in modern life, but improper use and disposal have resulted microplastics becoming widespread the environment, raising significant concerns about both environment human health. Extensive research has explored transformation mechanisms, bioaccumulation, ecological impacts, health risks associated with microplastics. The present review first analyzes migration, transformation, degradation pathways of on global scale, then synthesizes current knowledge types, sources, migration soil, atmosphere, aquatic environments, emphasizing mechanisms like photo-aging microbial degradation, detailing their impacts. Additionally, this examines gaps identifies critical areas needing further study, such as key control points microplastic processes underlying to populations. aim is provide comprehensive reference for advancing pollution control, protection efforts, risk assessment frameworks.
