ClearAnalysis of Land Use Evolution of Suzhou Wetlands Based on RS and GIS
Researchers used satellite remote sensing and GIS to track changes in land use and wetland coverage in Suzhou, China over time. Understanding how wetland ecosystems change is important for assessing their capacity to filter pollutants, including microplastics carried by stormwater and runoff.
The Changes in Dominant Driving Factors in the Evolution Process of Wetland in the Yellow River Delta during 2015–2022
This paper is not about microplastics; it uses satellite time-series imagery to analyze changes in wetland area and type in the Yellow River Delta between 2015 and 2022.
Spatiotemporal changes in land use and residential satisfaction in the Huai River-Gaoyou Lake Rim area
Researchers used two decades of satellite data to track land use changes and ecological risks in China's Jiangsu Province, focusing on shifts between agricultural, urban, and wetland areas. Land use changes alter how plastic waste and microplastics are transported and deposited in freshwater ecosystems.
Priorities identification of habitat restoration for migratory birds under the early dry season: A case study of Poyang Lake and Dongting Lake wetlands, China
This paper is not about microplastics; it develops a priority framework for wetland habitat restoration for migratory birds at Poyang Lake and Dongting Lake in China, focusing on ecological and landscape analysis with no connection to microplastic research.
Distribution and characteristics of microplastics in the sediments of Poyang Lake, China
Researchers found microplastic contamination in sediments across Poyang Lake, China, with abundances ranging from 11 to 3,153 items per kilogram dry weight, and identified significant spatial variability linked to human activity and hydrological conditions.
Bacterial community structure of water, sediment and microplastics in Poyang Lake wetland.
This study compared the bacterial communities living on four types of microplastics (film, foam, fiber, and fragment) in Poyang Lake wetland in China against the bacterial communities in the surrounding water and sediment. The microplastic surfaces hosted distinct microbial communities that differed from both the water and sediment, with foam microplastics supporting the least diverse communities. This "plastisphere" research is important because the unique bacteria colonizing plastic surfaces could spread pathogens or alter nutrient cycles in freshwater wetland ecosystems.
The current situation of water pollutants and pollution source in Poyang Lake: A review
This review of pollution in China's largest freshwater lake, Poyang Lake, finds that microplastics are accumulating alongside heavy metals and elevated nitrogen and phosphorus from industrial discharge and human activity. Because Poyang Lake feeds the Yangtze River and supports major fisheries, microplastic buildup there has potential downstream consequences for aquatic ecosystems and the people who depend on them.
[Distribution Characteristics of Microplastic Surface Bacterial Communities Under Flooded and Non-flooded Conditions in Nanjishan Wetland of Poyang Lake].
A 16S sequencing study of bacterial communities in the Poyang Lake wetland found that microbial diversity on microplastic surfaces was lower than in surrounding sediment and water, with the microplastic biofilm community shifting between sediment-like (non-flooded) and water-like (flooded) profiles depending on water level. The plastisphere communities were dominated by distinct bacterial genera including elevated Proteobacteria, suggesting that microplastics select for specific microbial assemblages in natural wetland ecosystems.
Monitoring Water Clarity Using Landsat 8 Imagery in Jiaozhou Bay, China, From 2013 to 2022
This paper is not about microplastics. It uses Landsat 8 satellite imagery to monitor water clarity changes in Jiaozhou Bay, China from 2013 to 2022, finding that rainfall and human activities are the primary drivers of transparency changes. The study focuses on remote sensing and water quality monitoring with no direct connection to microplastic pollution.
Eco-Asset Variations and Their Driving Factors in the Qinghai–Tibet Plateau, China, under the Context of Global Change
This paper is not relevant to microplastics research — it analyzes ecological asset changes and their environmental drivers on the Qinghai-Tibet Plateau using remote sensing data.
Estimated microplastic stress and potential affiliated toxic elements on phytoplankton in a floodplain-lake system
Microplastics and their associated toxic elements were assessed in phytoplankton from Poyang Lake, China during the dry season, with the study examining how MP stress and co-transported pollutants affect the lake's primary producers.
Response Time of Vegetation to Drought in Weihe River Basin, China
This is a hydrology study analyzing how vegetation in China's Weihe River Basin responds to drought using satellite vegetation indices; it is not a microplastics research paper.
Microplastic abundance, distribution and composition in water, sediments, and wild fish from Poyang Lake, China
Microplastics were measured in surface water, sediments, and fish (crucian carp) across Poyang Lake, China's largest freshwater lake, finding 5–34 items/L in water, 54–506 items/kg in sediments, and 0–18 items per fish, with heterogeneous spatial distribution related to anthropogenic and topographic factors. The study provides comprehensive multi-compartment baseline data on microplastic contamination in a major Chinese freshwater ecosystem.
Effects of microplastics on bacterial communities in lake wetland sediments: a comparison between drought and flooded conditions
Researchers established a sediment microcosm system for Poyang Lake wetland and examined the effects of polyethylene and polypropylene microplastics on bacterial community structure, functional genes, and ecological processes over 180 days under both simulated drought and flooded conditions.
From particle tracking modelling to species impact forecasting: a framework for microplastic exposure risk quantification in the largest freshwater lake of China
Using a hydrodynamic model coupled with particle tracking, researchers simulated microplastic transport, distribution, and impact zones in Poyang Lake, China's largest freshwater lake. The model revealed seasonal variation in MP accumulation hotspots driven by water level fluctuations, and predicted high-risk zones for aquatic organisms.
How hydrodynamic conditions dominate the microplastic footprint in the largest freshwater lake in China
Researchers collected microplastics from surface water across China's Poyang Lake and used hydrodynamic flow data to model how three dominant particle types—PE fibers, PP fragments, and PE films—migrate under different flow conditions. Hydrodynamic conditions were the dominant control on microplastic spatial distribution, with still-water zones accumulating the highest concentrations.
Occurrence and distribution of microplastics in China’s largest freshwater lake system
Researchers found high levels of microplastics in both water and sediment across China's largest freshwater lake system, Poyang Lake, with concentrations up to 1,064 particles per cubic meter in water. The study reveals widespread contamination even in protected nature reserves, emphasizing the scale of the freshwater microplastics problem.
Impact of Water Level Fluctuation on Microplastic Transportation and Redistribution in a Floodplain Lake System
This study examined how seasonal water level fluctuations in a Chinese floodplain lake affect microplastic transportation and redistribution, finding that flood pulses redistribute MPs across the floodplain and that rising and falling water levels create distinct accumulation patterns.
Spatial and temporal distributions of microplastics and their macroscopic relationship with algal blooms in Chaohu Lake, China
Researchers examined the spatial and temporal distribution of microplastics in Chaohu Lake, China during wet and dry seasons, finding average concentrations of 2,133 particles per cubic meter in the dry season and 1,679 in the wet season. At a macroscopic level, microplastic distribution patterns correlated with algal bloom density, nutrient levels, and population distribution.
Assessing wetlands ecological risk through an adaptive cycle framework
Not relevant to microplastics — this paper develops an ecological risk assessment framework for wetlands based on adaptive cycle theory, applied to Kunshan, China, focusing on climate change and human impacts rather than plastic contamination.
