Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to this Special Issue of Water entitled "Soil, Water and Agri-Food Matrices—Integrated Analytical Strategies for Organic Pollutants". This Special Issue aims to bring together high-quality research and critical perspectives addressing the analytical challenges associated with the occurrence and fate of organic pollutants across interconnected environmental and agri-food compartments.

Organic pollutants in soil, water, and agri-food matrices remain a persistent challenge for environmental protection and food safety, intensified by agricultural inputs, industrial emissions, and wastewater-derived contamination. Within the soil–water–food nexus, contaminants such as pesticides, pharmaceuticals, PFAS, industrial chemicals, and their transformation products can be transferred between compartments, creating combined exposure scenarios that align with the One Health perspective.

This Special Issue focuses on advanced, fit-for-purpose analytical chemistry workflows that enable robust detection, confident identification, and accurate quantification of organic pollutants in complex matrices. We particularly welcome studies employing LC/GC coupled to HRMS (e.g., Orbitrap, QTOF) and integrated strategies combining targeted and non-targeted analysis or suspect screening, supported by transparent data-processing pipelines (feature extraction, spectral interpretation, libraries/in silico tools, confidence levels). Strong emphasis is placed on QA/QC, method validation, matrix effects management, and measurement uncertainty, ensuring comparability and regulatory relevance. Contributions on greener sample preparation, harmonized protocols, and interlaboratory performance are also encouraged. By focusing on advanced analytical chemistry approaches and harmonized workflows, this Special Issue aims to stimulate interdisciplinary dialogue among environmental scientists, analytical chemists, and food safety experts, fostering robust and reproducible strategies that support monitoring, risk assessment, and regulatory decision-making. Topics include (but are not limited to) the following:

  • Integrated soil–water–agri-food monitoring strategies (One Health, exposure pathways).
  • Sampling design, representativeness, and spatiotemporal variability.
  • Green and high-performance sample preparation (QuEChERS variants, SPE, microextraction, DES/NADES, etc.).
  • LC–HRMS/GC–HRMS workflows: target, suspect, non-target screening.
  • Transformation products, metabolites, and effect-directed analysis links.
  • Data processing, chemometrics, identification confidence, and reporting standards.
  • QA/QC plans, validation, matrix effects, and measurement uncertainty.
  • Harmonization, interlaboratory comparisons, and decision-making for risk assessment/regulation.

As the core water source area of the Middle Route of the South-to-North Water Diversion Project, the Danjiangkou Reservoir Area plays a critical role in regional ecological security and water resource security. Its land use transitions and associated ecosystem service dynamics are examined. Based on land use, ecological sensitivity, and ecosystem service value data from 2000 to 2020, this study employed the FLUS model to simulate four scenarios—natural development, cropland protection, ecological protection, and ecological–cropland synergy—for 2050, systematically revealing the characteristics of land use transition, the coupled evolution of ecological sensitivity and ecosystem service value, and the trade-off mechanisms between ecological security and food security under multiple scenarios. The results show that: (1) From 2000 to 2020, land use in the reservoir area exhibited an ecological transition characterized by “two expansions and three contractions”: forestland and water bodies increased by 764.16 km2 and 324.36 km2, respectively, while cropland and grassland decreased by 664.33 km2 and 547.08 km2, the comprehensive index of land use degree declined by approximately 1.0%, indicating continuously weakening development intensity. (2) The overall hierarchical structure of ecological sensitivity improved, with the area of highly sensitive zones decreasing from 5201.60 km2 to 3729.91 km2; however, the concentration risk of highly sensitive forestland and the unexpected increase in extremely sensitive cropland persisted. (3) Total ecosystem service value increased from CNY 51.92 billion to CNY 58.35 billion (+12.38%), with hydrological regulation contributing 79.83% of the total increment; regulating services remained the core functional type. Sensitivity analysis indicated that the coefficient of sensitivity (CS) values were below 1, confirming the robustness of the findings. (4) Multi-scenario simulations revealed a rigid ecological–food security trade-off: under natural development, ESV increased by 15.44% but cropland loss reached 1033.29 km2; under cropland protection, ESV decreased by 1.50%, the only scenario with negative ecological outcomes; under ecological protection, ESV increased by 16.59% but with the most severe cropland loss (−1072.98 km2); under ecological–cropland synergy, water bodies expanded the most substantially (+562.75 km2) while cropland loss was the most severe (−1118.19 km2), indicating that the synergy goal was not achieved, as gains in regulating services came at the cost of further provisioning services losses. The study confirms the positive effects of ecological land use transition in the reservoir area, while also highlighting the intensifying conflict between ecological protection and food security against the backdrop of ecological improvement.
