Study on the Synergistic Effects of Karst Carbon Sink and Vegetation Carbon Sink in Watersheds under Different Geological Backgrounds—A Case Study of Darongjiang and Lingqu Watersheds Water (IF 3.4) Pub Date : 2024-04-22 Xue Wang, Xiangling Tang, Shi Yu, Xuemei Zhong
In this study, the hydrochemistry-runoff method and remote sensing estimation method were used to calculate the karst carbon sink flux (KCSF) and the forest vegetation carbon sequestration flux (FVCSF) in Darongjiang (DRJ) and Lingqu (LQ) watersheds. The results show the following: (1) The KCSF in DRJ and LQ watersheds is 238.43 × 105 t·y−1 and 353.44 × 105 t·y−1, respectively. Influenced by changes

Comparative Inactivation of the RNA of the Delta and Omicron Variants of SARS-CoV-2 in Wastewater of Five Municipalities in Southeast Germany Water (IF 3.4) Pub Date : 2024-04-22 Michael Geissler, Roger Dumke
During the COVID-19 pandemic, wastewater-based epidemiology has been extensively used as a helpful tool for evaluation of the epidemic situation in catchments of wastewater treatment plants. In this context, knowledge about the rate of virus inactivation in wastewater is important for characterization of the influence of retention times in sewers on virus concentrations, of the storage periods before

Water and Energy Sustainability of Swimming Pools: A Case Model on the Costa Brava, Catalonia Water (IF 3.4) Pub Date : 2024-04-19 Juan-Jose Gomez-Guillen, Núria Arimany-Serrat, David Tapias Baqué, David Giménez
The aim of this research is to propose a more sustainable swimming pool, in terms of water and energy, in the Costa Brava area. The methodology is focused on the creation of a descriptive water and energy model for swimming pools and their monitoring, to propose the transition to a more sustainable swimming pool, in the context of climate change. The research is characterized by an exploratory, descriptive

Zooplankton Temporal, Longitudinal, and Vertical Diversity Patterns in the Floodplains of the Western Amazon Water (IF 3.4) Pub Date : 2024-04-20 Fernando Sánchez, Francisco Cuesta, Gabriela Echevarría
The Western Amazon is a highly biodiverse area. Zooplankton diversity studies in the region have been primarily conducted in Peru and Colombia, with limited research in the Ecuadorian Amazon. To address this gap, our research aimed to enhance taxonomic knowledge and understand zooplankton diversity patterns in the Napo and Pastaza lower basins at different spatial and temporal scales. Two sampling

Advances in Water Resource Management: An In Situ Sensor Solution for Monitoring High Concentrations of Chromium in the Electroplating Industry Water (IF 3.4) Pub Date : 2024-04-20 Giulia Mossotti, Andrea Piscitelli, Felice Catania, Matilde Aronne, Giulio Galfré, Andrea Lamberti, Sergio Ferrero, Luciano Scaltrito, Valentina Bertana
Concerning environmental safety and mitigating the risk of water pollution, the electroplating industry, historically reliant on the use of elevated concentrations of heavy metals to achieve high-quality products, faces a crucial challenge in monitoring wastewater enriched with these metals, notorious for their adverse effects on ecosystems and human health. Chromium, in both oxidation states Cr (III)

Integrating Microseismic Monitoring for Predicting Water Inrush Hazards in Coal Mines Water (IF 3.4) Pub Date : 2024-04-20 Huiqing Lian, Qing Zhang, Shangxian Yin, Tao Yan, Hui Yao, Songlin Yang, Jia Kang, Xiangxue Xia, Qixing Li, Yakun Huang, Zhengrui Ren, Wei Wu, Baotong Xu
The essence of roof water inrush in coal mines fundamentally stems from the development of water-bearing fracture zones, facilitating the intrusion of overlying aquifers and thereby leading to water hazard incidents. Monitoring rock-fracturing conditions through the analysis of microseismic data can, to a certain extent, facilitate the prediction and early warning of water hazards. The water inflow
