ClearIdentifying the characteristics of and factors driving spatiotemporal water quality variations in the Yellow River Basin, China, from 2008 to 2020
This study analyzed water quality data from the Yellow River Basin in China from 2008 to 2020, identifying pollution sources and spatial trends across the watershed. While focused on general water quality rather than microplastics specifically, such assessments provide important context for understanding pollution dynamics in large river systems.
[Occurrence Characteristics and Ecological Risk Assessment of Microplastic Pollution in the Yellow River Basin].
Researchers examined the spatial distribution, composition characteristics, and ecological risks of microplastic pollution across the Yellow River Basin in China, assessing contamination levels in the nation's historically significant waterway system.
Occurrence and Risk Assessment of Microplastics in a Source Water Reservoir in Middle Reaches of Yellow River
Researchers assessed microplastic occurrence and associated risk in a source water reservoir in Malaysia, detecting particles across multiple sampling sites and identifying dominant polymer types and size fractions relevant to drinking water safety.
The role of water management and its effect on microplastic transport and fate
This study examined how water management decisions, such as dam operations and irrigation withdrawals, influence microplastic concentrations and transport in river systems. Flow regulation was found to alter how microplastics accumulate and flush through river networks.
Managing Urban Water Resources: A Review of Challenges, Techniques, and Sustainability Strategies
Despite its title referencing urban water resource management, this paper is a broad review of water management challenges and tools — including hydrological modeling, remote sensing, and integrated governance strategies — rather than a study of microplastic pollution. It reviews planning frameworks and case studies related to water sustainability and does not examine microplastics or their health effects.
Distribution of microplastics in Lanzhou section of the Yellow River: Characteristics, ecological risk assessment, and factors analysis
Researchers surveyed microplastic contamination in surface water and sediments along the Lanzhou section of China's Yellow River. They found that most particles were small fibrous fragments of PET and polypropylene, with higher abundances during the dry season, and that human activity and weather patterns influenced microplastic distribution. Ecological risk assessments indicated the overall pollution level in this stretch of the river was relatively low.
The role of water management and its effect on microplastic transport and fate
Researchers examined how water management practices affect the transport and fate of microplastics in river networks, which serve as both conduits and sinks for plastic pollution. The study found that flow regulation and water management interventions significantly influence how far microplastics travel and where they accumulate.
Contributions from typical sources to microplastics in surface water of a semiarid urban river
Researchers quantified the contributions of typical sources to microplastic pollution in the Yellow River's Lanzhou section. The study found that wastewater treatment plant effluent and urban tributaries were the dominant sources, with fibers and fragments composed mainly of polyethylene terephthalate and polyamide, highlighting the role of urban areas in river microplastic contamination.
Supplying demands of aquatic ecosystems using bivariate optimization of water depletion strategies under uncertainty
This study used bivariate optimization modeling to develop water management policies for rice cultivation that simultaneously minimize water use and reduce nitrate pollution in paddy ecosystems. Sustainable irrigation practices that reduce nutrient runoff are also relevant to limiting microplastic transport from agricultural fields into downstream water bodies.
From Planning to Action: Advancing Sustainable Water Resources Management in the Potomac Basin
Not relevant to microplastics — this paper focuses on collaborative water resources planning in the Potomac River basin, examining governance frameworks and stakeholder engagement strategies.
Microplastic pollution in sophisticated urban river systems: Combined influence of land-use types and physicochemical characteristics
This study assessed microplastic pollution across an urban river network in China, finding that land-use type and water physicochemical properties jointly influence microplastic distribution, with industrial and residential areas contributing highest loads.
Pollution characteristics and prospective risk of microplastics in the Zhengzhou section of Yellow River, China
Researchers analyzed microplastic pollution across fourteen sampling sites in the Zhengzhou section of the Yellow River in China. The study found microplastic concentrations ranging from 2.33 to 15.50 particles per liter, higher than other inland Chinese rivers, with fibers and fragments being the dominant types and polyethylene the most common polymer.
[Microplastics pollution in the Yellow River basin: current status and control strategy].
This review summarizes microplastic contamination in the Yellow River basin, finding that pollution increases from upstream to downstream with the highest concentrations in the Yellow River Delta wetland, and that both sediment and surface water are impacted at levels posing risks to aquaculture and human health.
Evolving environmental awareness and shifts in management priorities: a socioeconomic lens on the min river basin, China
Not relevant to microplastics — this paper uses socioeconomic analysis and machine learning to study shifting environmental management priorities in China's Min River basin, focusing on water quality and land use.
The effects of land use types on microplastics in river water: A case study on the mainstream of the Wei River, China
Researchers studied how different land use types along China's Wei River, a major tributary of the Yellow River, influence microplastic concentrations in the water. The study found that urban and agricultural areas contributed more microplastics than other land use types, with seasonal variations also playing a role, highlighting how human activities directly shape plastic pollution patterns in river systems.
Effects of irrigation on the fate of microplastics in typical agricultural soil and freshwater environments in the upper irrigation area of the Yellow River
Researchers investigated how irrigation affects microplastic distribution in agricultural soil and nearby waterways along the Yellow River. They found that irrigation increased microplastic concentrations in surface water and sediment while pushing smaller particles deeper into soil, suggesting that river water irrigation causes secondary microplastic pollution in agricultural environments.
Microplastic pollution in the Yangtze River: Characterization, influencing factors, and scenario-based predictions using machine learning method
Microplastic pollution in the Yangtze River was characterized across multiple sampling sites, documenting spatial patterns in particle abundance, polymer types, and size distributions. As one of the world's largest rivers, the Yangtze's microplastic burden has major implications for plastic delivery to the Pacific Ocean.
New Model for Quantifying the Impact of the Social Economy on Water Resources’ Sustainability
This study models correlations between social economy indicators and water resource sustainability across EU27 countries, finding that environmental protection spending tends to cover ecological objectives even when exceeding budget allocations. The study is not related to microplastic research.
A Comprehensive Method for Water Environment Assessment considering Trends of Water Quality
Researchers developed a comprehensive water quality assessment method that accounts for both current pollution levels and trends over time, applying it to rivers feeding a major Chinese reservoir. Water quality assessment frameworks are increasingly being adapted to include microplastic contamination as a standard monitoring parameter.
