ClearA Comprehensive Analysis of Agricultural Non-Point Source Pollution in China: Current Status, Risk Assessment and Management Strategies
This review analyzes agricultural pollution in China from fertilizers, pesticides, plastic films, livestock, and crop waste, and finds widespread nitrogen, phosphorus, and heavy metal contamination across provinces. Microplastic pollution from agricultural plastic films was assessed as low risk, but heavy metals like arsenic and cadmium pose serious cancer risks to adults and children. The study recommends strategies focused on reducing pollution at the source to protect both farmland and human health.
Water Pollution and Agriculture: Multi-pollutant Perspectives
This review examines agriculture as a multi-pollutant source of water contamination, identifying large spatial and temporal variation in nutrient, pesticide, plastic, and pathogen loads and arguing that agricultural water management strategies must account for these simultaneous pollutant interactions.
Current challenges, methods, and strategies for reducing the transfer of nonpoint source pollution from agricultural areas to surface water
This review synthesizes strategies for reducing nonpoint source agricultural pollution transfer to surface waters, evaluating measures including riparian buffer zones, constructed wetlands, denitrifying bioreactors, and permeable barriers in the context of their biophysical and hydrological effectiveness. The authors highlight microplastics and nanoplastics as emerging global challenges in agricultural diffuse pollution and identify fragmented governance and economic constraints as persistent barriers to implementation.
Watershed-Based Governance for Agricultural Non-Point Source Pollution: Empirical Insights from the Yangtze River Economic Belt
Researchers examined how China's 'Guiding Opinions on Strengthening Agricultural Non-Point Source Pollution Prevention and Control' affected pollutant emissions across the Yangtze River Economic Belt, using econometric analysis across three governance pathways. They found the policy significantly reduced emissions by curbing mulch film use and consolidating breeding farms, but had no measurable effect on rural domestic pollution due to pre-existing infrastructure investments.
Water pollution from food production: lessons for optimistic and optimal solutions
Researchers proposed a multi-pollutant framework for assessing water pollution from food production, drawing lessons from how air quality science handles multiple contaminants simultaneously. The study argues that future water quality assessments should better integrate economic and social goals alongside environmental targets, using participatory approaches to develop practical and politically feasible solutions.
Research on Watershed Water Pollution Control Technologies and Comprehensive Water Quality Improvement Solutions
This review covers water pollution control technologies and comprehensive strategies for improving watershed water quality in China. Controlling pollution at the watershed scale is essential for reducing microplastic and chemical contaminant loads in rivers and drinking water sources.
Identification of surface water quality pollution areas and pollution sources based on spatial clustering and random forest in Henan, China
This study used spatial cluster analysis to identify surface water quality pollution areas and trace pollution sources across Henan Province, China. Spatial dependence analysis revealed distinct contaminated zones and their likely sources, enabling targeted remediation strategies for different pollution types.
Distribution, Environmental Risk Assessment, and Key Drivers of Microplastics in Farmland Soils Across Agricultural Zones in China
Researchers mapped the distribution and environmental risk of microplastics across a study area while identifying the key drivers of spatial variation, including land use and proximity to pollution sources. The findings provide a framework for prioritizing cleanup and management efforts in microplastic-contaminated environments.
Soil Pollution Status, Sources and Control Methods in China
This review examined soil pollution sources, status, and control methods in China, covering industrial activity, agriculture, and urbanization as primary drivers of contamination. The paper discussed how soil pollution degrades agricultural output, contaminates water, and affects air quality, and surveyed available remediation strategies.
Managing contaminants in farmed soils: case studies from China
This chapter examines agricultural soil contamination in China — where 16.1% of surveyed sites are polluted — using case studies to illustrate strategies for managing heavy metals, microplastics, and other contaminants in farmed soils with implications for food safety.
Basin-Scale Pollution Loads Analyzed Based on Coupled Empirical Models and Numerical Models
This study used a combination of field measurements and computer models to quantify pollutant loads from different sources across a Chinese river basin. Better tools for tracking pollution sources at basin scale can support efforts to reduce microplastic and other contaminant inputs to waterways.
The Current State of the Problem of Assessing the Characteristics of Water Bodies Diffuse Pollution in Lowland Watersheds
This review examines current approaches to assessing diffuse (non-point source) pollution in lowland watersheds, where runoff from agricultural and urban land carries dissolved and suspended pollutants into water bodies. The authors identify gaps in modeling and monitoring methods for these complex, widespread pollution pathways.
Rural Ecological Problems in China from 2013 to 2022: A Review of Research Hotspots, Geographical Distribution, and Countermeasures
This review analyzed a decade of research on rural ecological problems in China from 2013 to 2022, identifying key hotspots including soil contamination, water pollution, and biodiversity loss driven by rapid urbanization and industrial development, and summarizing proposed countermeasures.
Integrated Ecological Risk Assessment of the Agricultural Area under a High Anthropopressure Based on Chemical, Ecotoxicological and Ecological Indicators
Researchers conducted an integrated ecological risk assessment of agricultural land using chemical, ecotoxicological, and ecological indicators, finding that while chemical analysis overestimated risk, the combined approach revealed most of the area had acceptable risk levels despite over a century of anthropogenic pressure.
Spatial Distributions, Compositional Profiles, Potential Sources, and Intfluencing Factors of Microplastics in Soils from Different Agricultural Farmlands in China: A National Perspective
Researchers conducted a nationwide survey of microplastics in Chinese agricultural soils, collecting 477 samples from 109 cities across 31 regions, and identified spatial distribution patterns and key factors influencing farmland microplastic contamination.
Agricultural Environmental Pollution, Risk Assessment, and Control
This book chapter reviews the growing burden of agricultural environmental pollution — from pesticide residues to microplastics and heavy metals — and evaluates risk assessment frameworks and control strategies for protecting soil health and food safety.
Risk assessment and zoning of soil microplastics in a typical megacity, China
Researchers mapped microplastic contamination across soils in Nanjing, a major Chinese city, and found that risk levels varied significantly by location. Residential areas, government districts, and industrial zones showed the highest concentrations, with washing-related activities and soil properties being key factors influencing pollution levels. The study provides a risk-based zoning framework that could help city planners prioritize cleanup and prevention efforts in the most affected areas.
Revealing the Full Picture of Agricultural Plastic Legacy Pollution: Toward “Zero‐Leakage” Management in Chinese Farmlands
This review examines the legacy of agricultural plastic mulch film pollution in Chinese farmlands, where China consumes approximately 68% of global mulch film production, leading to persistent residue accumulation and microplastic contamination. The authors propose a 'zero-leakage' management framework to address the full spectrum of plastic pollution across different environmental compartments in agricultural settings.
