Data and code for: Socioeconomic and hydrodynamic controls on microplastic export in the Three Gorges Reservoir
AI summary Read the abstract
Researchers built a computer model to track how tiny plastic particles (microplastics) flow through China's massive Three Gorges Reservoir, factoring in things like local economic activity, rainfall, and water movement patterns. This matters because reservoirs like this one supply drinking water to millions of people, and understanding what drives microplastic pollution—and how it might change through 2065—can help communities and policymakers reduce contamination before it reaches your tap. Note: this dataset paper shares the tools and data behind the study rather than the full results, so it's a resource for other scientists to build on.
This dataset and code repository support the findings presented in "Socioeconomic and hydrodynamic controls on microplastic export in the Three Gorges Reservoir". It contains: (i) observational data for model validation, including environmental conditions (precipitation, dissolved oxygen, water temperature, hydraulic residence time), compiled microplastic physicochemical characteristics and spatial abundance from published field studies (2016, 2022), and district-level GDP; and (ii) process-based modeling code and simulation outputs for microplastic export flux estimation and future scenario projections (2015–2065). All data sources, software requirements, and script execution order are documented in the read me file.

Scientists built a computer model to track how microplastics (tiny plastic particles) flow through China's massive Three Gorges Reservoir, linking pollution levels to local economic activity and water conditions like rainfall and temperature. This matters because reservoirs like this one supply drinking water and food to millions of people, and understanding what drives microplastic pollution now—and predicting how it might change through 2065—can help communities and policymakers reduce our exposure to these particles before they reach our taps and food supply.
Microplastics in surface waters and sediments of the Three Gorges Reservoir, China
AI summary Read the abstract
Researchers sampled surface waters and sediments of the Three Gorges Reservoir in China and found microplastic contamination throughout, with concentrations influenced by water flow dynamics and proximity to human settlements.
Catchment-wide flooding significantly altered microplastics organization in the hydro-fluctuation belt of the reservoir
AI summary Read the abstract
Researchers investigated the effect of catchment-wide flooding on microplastic distribution in the hydro-fluctuation belt of the Three Gorges Reservoir in China, finding that flooding reduced local microplastic density from 7,633 to 4,875 particles per kilogram while transporting an estimated 5 times 10 to the 11 microplastic items into the reservoir. Approximately 15.8% by weight of the plastic flux that the Yangtze River delivers to the ocean was attributed to this single flooding event.

AI summary Read the abstract
This is a dataset and code package, not a research study. It provides data, computer notebooks and models tracking microplastic pollution release, movement, and buildup in China's rivers from 2000 to 2100, including future scenarios for managing this pollution.
The hydro-fluctuation belt of the Three Gorges Reservoir: Source or sink of microplastics in the water?
AI summary Read the abstract
The water-level fluctuation zone of the Three Gorges Reservoir in China was found to be both a source and sink for microplastics depending on season, with high concentrations of plastic particles in the sediment. This large reservoir acts as an accumulation point for microplastics from upstream rivers.
