Hydrochemical Evolution and Nitrate Source Identification of River Water and Groundwater in Huashan Watershed, China
Combined hydrochemical analysis, factor analysis, and isotopic methods were applied to trace nitrate sources and transformations in river water and groundwater of the Huashan watershed in China.

Groundwater–Surface Water Interactions: Recent Advances and Interdisciplinary Challenges
This review covers recent advances in understanding groundwater–surface water interactions, including their importance for drinking water security and contaminant transport, and argues for interdisciplinary approaches that combine hydrology, ecology, and geochemistry.
Spatiotemporal Dynamics of Land Use Changesand Their Impacts on Ecosystem ServiceValue in the Qinghai Lake Basin, 2003-2023
Researchers examined spatiotemporal land use changes and their effects on ecosystem service value in the Qinghai Lake Basin of the Qinghai-Tibet Plateau over a 20-year period from 2003 to 2023. The study found that land use alterations significantly disrupted biodiversity, soil retention, water conservation, and overall ecosystem service value in this important inland saltwater lake region.
Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province
This study analyzed the chemical characteristics and origins of water in the Ciyao River Basin, a water-scarce region in China's Shanxi Province. Researchers collected water samples across wet, normal, and dry seasons and found that the water chemistry was influenced by both natural rock weathering and human activities. The findings provide baseline data for managing water quality in regions where water scarcity makes understanding pollution sources especially critical.
Soil Salinity Weakening and Soil Quality Enhancement after Long-Term Reclamation of Different Croplands in the Yellow River Delta
Researchers examined how long-term agricultural reclamation of saline soils in China's Yellow River Delta affected soil salinity and quality, finding that reclamation progressively reduced salinity and improved soil quality indices across different cropping 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.
Study on the Influence of Mining Activities on the Quality of Deep Karst Groundwater Based on Multivariate Statistical Analysis and Hydrochemical Analysis
This study examined how long-term coal mining activities in China affected deep karst groundwater chemistry, finding significant changes to water quality that threaten safe drinking water supply in mining regions.
The effect of agricultural intensification and water-locking on the world's largest coastal lagoonal system
Palaeolimnological reconstruction of Mirim Lagoon in southern Brazil revealed that estuarine water-locking for agriculture in the 20th century triggered eutrophication and increased sedimentation rates, with subsequent intensification of rice and soybean production causing major shifts in organic matter isotopic composition while trace metal concentrations remained near natural background levels.
Identification of Hydrochemical Characteristics, Spatial Evolution, and Driving Forces of River Water in Jinjiang Watershed, China
This paper is not about microplastic pollution. It analyzes the hydrochemical characteristics of river water in the Jinjiang Watershed in China, identifying rock weathering, mining, agricultural runoff, and domestic pollution as the main factors influencing water chemistry.
Estimating Groundwater Recharge and Precipitation Sources of the Zamora River Basin, Southeastern Ecuador, by Using GIS and Stable Isotopes
This paper is not about microplastics; it uses stable isotopes and GIS-based water balance models to study groundwater recharge mechanisms in the Zamora River Basin in Ecuador.
Yellow River Basin Management under Pressure: Present State, Restoration and Protection II: Lessons from a Special Issue
This review assessed the current state of the Yellow River Basin's water environment, covering sediment dynamics, pollution loads, and restoration challenges, along with management interventions aimed at improving ecological conditions. The authors document improvements from recent restoration policies but identify persistent pressures from agriculture, industry, and climate change threatening the basin's long-term water security.
Impact Imposed by Urbanization on Soil Heavy Metal Content of Lake Wetland and Evaluation of Ecological Risks in East Dongting Lake in China
This Chinese study measured heavy metal contamination in wetland soils of East Dongting Lake, finding elevated concentrations of several metals linked to nearby industrial and agricultural activities. Wetland contamination with heavy metals often co-occurs with microplastic pollution, and these combined stressors can have synergistic harmful effects on wetland ecosystems.
Characteristics of Hydrochemistry and Stable Isotopes in a Karst Region in Samcheok, Republic of Korea
This study monitored water chemistry and stable isotopes in a karst region in South Korea across different seasons and years, finding that land use and seasonal variation strongly influenced groundwater quality. Karst aquifers are vulnerable to contamination from surface runoff, including microplastics from agricultural and urban sources.
Assessment of the groundwater recharge processes of a shallow and deep aquifer system (Maggiore Valley, Northwest Italy): a hydrogeochemical and isotopic approach
Researchers analyzed water chemistry and isotopes across shallow and deep groundwater systems in northwest Italy, tracing how water from distant mountain recharge zones mixes before reaching a heavily used drinking water well field. The study clarifies potential pathways for pollutants to reach drinking water supplies, providing critical information for protecting this major regional water resource.
Evaluating the Human–Water Relationship over the Past Two Decades Using the SMI-P Method across Nine Provinces along the Yellow River, China
This study evaluated the human-water relationship across nine provinces along China's Yellow River over two decades. Researchers found that harmony between human systems and water systems has consistently improved since 2002, though downstream provinces have progressed faster than upstream ones, and no province has yet reached a high level of balance.
Relationships between soil salinity and economic dynamics: Main highlights from literature
This bibliometric review of soil salinity research found that most studies focus on agricultural strategies for managing salinity, food security, desertification, and climate change impacts, while direct assessments of socioeconomic impacts from soil salinity and broader sustainability dimensions have received comparatively little attention.
Using lake sediments to assess the long-term impacts of anthropogenic activity in tropical river deltas
