[Microplastics pollution in the Yellow River basin: current status and control strategy].
AI summary Read the abstract
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.
Microplastics pollution has attracted worldwide attention. Compared with the status quo of microplastics pollution in marine environment and other major rivers and lakes, the relevant data of the Yellow River basin is relatively inadequate. The abundance, types, and spatial distribution characteristics of microplastic pollution in the sediments and surface water of the Yellow River basin were reviewed. Meanwhile, the status of microplastic pollution in the national central city and Yellow River Delta wetland was discussed, and the corresponding prevention and control measures were put forward. The results showed that the spatial distribution of microplastics pollution in sediments and surface water of the Yellow River basin increased from upstream to downstream, especially in the Yellow River Delta wetland. There are obvious differences between the types of microplastics in sediment and surface water in the Yellow River basin, which is mainly related to the materials of microplastics. Compared with similar regions in China, the microplastics pollution levels in national key cities and national wetland parks in the Yellow River basin are in the medium to high degree, which should be taken seriously. Plastics exposure through various ways will cause serious impact on aquaculture and human health in the Yellow River beach area. To control microplastic pollution in the Yellow River basin, it is necessary to improve the relevant production standards, laws and regulations, and improve the capacity of biodegradable microplastics and the degradation capacity of plastic wastes.

AI summary Read the abstract
Researchers reviewed the extent and distribution of microplastic pollution across China's Yellow River Basin — one of the world's most important river systems — finding contamination in both water and sediment, and calling for better monitoring and control strategies to protect the region's ecosystems and the people who rely on them.
Microplastics in Yellow River Delta wetland: Occurrence, characteristics, human influences, and marker
AI summary Read the abstract
Microplastics were surveyed across different zones of the Yellow River Delta wetland with varying levels of human activity, finding widespread contamination even in protected areas with minimal human presence, with MP abundances ranging from 136 to 2060 items/kg. The study identifies direct human activities as a stronger driver of wetland microplastic contamination than tourism.
Research Progress and Prospects on the Pollution Status of Microplastics in the Yellow River Basin
AI summary Read the abstract
This review pulls together existing research on microplastic pollution in China's Yellow River Basin, a major water source for millions of people, finding that tiny plastic particles are seeping in from factory wastewater, farm runoff, and household trash. The takeaway: this pollution is hard to clean up and will require coordinated action at multiple levels, which matters because these microplastics can travel through the water supply and ecosystem, raising concerns about long-term exposure for the people and wildlife who depend on this river.
[Distribution, Sources, and Risk Assessment of Microplastics in Surface Sediments of Yellow River Delta Wetland].
AI summary Read the abstract
Researchers surveyed microplastic pollution in surface sediments of the Yellow River Delta wetland and found concentrations ranging from 20 to 520 particles per kilogram, primarily consisting of fibers. The dominant polymer types included rayon, polyethylene, polyester, and PET, with most particles larger than 1 mm. Pollution index assessments indicated the wetland was at a slightly polluted level with relatively low ecological risk overall.
