Topic Information

Dear Colleagues,

Sustainable water resource management requires a comprehensive understanding of how essential mineral nutrients and harmful contaminants are transported within aquatic systems. Water serves not only as a key carrier of health-promoting elements, such as calcium, magnesium, fluoride, and selenium, but also as a vector for pollutants that threaten environmental and public health. While mineral nutrients are critical for physiological functions including bone health, metabolism, and disease prevention, their spatial variability may lead to region-specific deficiencies or toxic accumulation. Simultaneously, the transport of contaminants, including inorganic compounds like heavy metals and nitrates, as well as organic pollutants such as pesticides, pharmaceuticals, and microplastics, poses serious ecological and health risks. These include carcinogenic, neurotoxic, and endocrine-disrupting effects, particularly under chronic low-level exposure scenarios. This Topic explores the mechanisms and drivers of nutrient and contaminant transport, aiming to inform sustainable strategies for water quality control. By integrating insights from hydrology, geochemistry, environmental engineering, and public health, it highlights the need for adaptive solutions that support both safe water access and long-term ecosystem resilience in the face of growing pollution pressures and water scarcity.

The list of specific topics covered in this Topic is as follows:

  1. Essential Mineral Nutrients in Water: Sources, Transport, and Health Implications.
  2. Aquatic Transport of Contaminants: From Heavy Metals to Microplastics.
  3. Geochemical and Hydrological Controls on Nutrient and Pollutant Mobility.
  4. Spatial Variability and Regional Risk of Nutrient Deficiency and Toxic Accumulation.
  5. Sustainable Water Resource Management under Pollution and Scarcity Stress.

Eutrophication increasingly threatens tropical freshwater systems, where nutrient enrichment drives harmful algal blooms and rapid water-quality decline.

Eutrophication increasingly threatens tropical freshwater systems, where nutrient enrichment drives harmful algal blooms and rapid water-quality decline. This study presents a validated satellite-based approach for retrieving total nitrogen (TN) and total phosphorus (TP) in Thai inland waters using Sentinel-2 imagery. A stratified sampling campaign collected 264 water samples from 50 lentic water bodies during April–May 2024. Results showed that key environmental predictors were identified through correlation analysis and integrated into multiple linear regression (MLR) and polynomial regression (PO) algorithms, with performance evaluated using 10-fold cross-validation. PO consistently outperformed MLR for both nutrients. For TN, PO achieved higher calibration accuracy (R2 = 0.63; RMSE = 4.74 mg/L) than MLR (R2 = 0.47; RMSE = 5.73 mg/L) and maintained strong validation performance (R2 = 0.76). For TP, PO likewise yielded superior cross-validation accuracy (R2 = 0.69; RMSE = 0.07 mg/L; IoA = 0.89) compared with MLR (R2 = 0.38; RMSE = 0.10 mg/L; IoA = 0.70). Spatial distributions of TN and TP derived from the imagery reinforced these findings. The PO-derived TN maps effectively captured nutrient hotspots associated with agricultural runoff, whereas the PO-based TP maps produced more stable and consistent spatial patterns. The findings demonstrate that Sentinel-2 can reliably retrieve TN and TP in tropical waters and offer a scalable pathway for improving nutrient surveillance and supporting science-based freshwater management in regions experiencing accelerating eutrophication.
