Hydroxyl radicals (•OH) play a crucial role in the fate of redox-active substances environment. Studies •OH production nature has been constrained to surface environments exposed light irradiation, but is overlooked subsurface under dark. Results this study demonstrate that abundant produced when sediments are oxygenated fluctuating redox conditions at neutral pH values. The cumulative concentrations within 24 h upon oxygenation 33 sampled from different 2–670 μmol per kg dry sediment or...
Chronic exposure to geogenic contaminated groundwaters (GCGs) has caused serious health problems among billions of people worldwide. The hydrogeological features, main sources hazardous substances, dominant hydrogeochemical processes and key factors controlling the occurrence high arsenic (As ≥ 10 μg/L), fluoride (F 1 mg/L), iodine (I 100 μg/L) groundwater are discussed in this review. Although global and/or regional occurrence, environmental geochemical behaviors As, F I have been well...
In this study, a highly sensitive liquid electrode discharge atomic emission source was developed for the determination of Cd and Zn in aqueous solutions.
In the present study, a novel and sensitive liquid spray dielectric barrier discharge induced plasma-chemical vapor generation technique (LSDBD-CVG) is developed for determination of lead concentration by inductively coupled plasma mass spectrometry (ICPMS). The dissolved Pb2+ readily converted to volatile species LSDBD chemical processes in presence 5% (v/v) formic acid supporting electrolyte (HCl, 0.01 mol L-1). this approach, sample solution aerosol simultaneously mixed with DBD generated...
Abstract Lacustrine groundwater discharge (LGD) is of great importance to the hydrological cycle and eco‐environment lakes. LGD often characterized by large spatial variability, but patterns have rarely been quantified, particularly at whole‐lake scales. This study presents quantitative estimation in an oxbow lake central Yangtze River Basins a segmented application 222 Rn mass balance model. The results show that rates all points ranged from 10.05 197.25 mm/d, with average 61.23 mm/d....
Accumulation of geogenic phosphorus (P) in groundwater is an emerging environmental concern, which closely linked to coupled processes involving FeOOH and organic matter under methanogenic conditions. However, it remains unclear how P enrichment associated with methane cycling, particularly the anaerobic oxidation (AMO). This study conducted a comprehensive investigation carbon isotopes dissolved inorganic (DIC), CO2, CH4, alongside Fe isotopes, microbial communities, functions quaternary...
Abstract Lacustrine groundwater discharge (LGD) is an important water and nutrient source for lakes. Despite its importance, high‐resolution quantifying the spatial variability of LGD remains challenging. Particularly, little studies have explored impact interaction zone structure between lakes aquifers on this variability. Present study presents a quantitative estimation patterns in oxbow lake by combining thermal remote sensing with 222 Rn mass balance model. The vertical distribution...
