Abstract Remediation of contaminated soil and sediment is important for improving the eco-environmental quality. Electro-kinetic remediation (EKR) an environmentally friendly technology to migrate remove pollutants from matrix. This paper analyses mechanism performance EKR heavy metals, organic pollutants, compound pollutants. Moreover, effect optimizing individual through pre-treatment (adding acid/oxidant/co-solvent/surfactant, stirring, heating, etc.), electrode optimization (exchange...
Methane bubble formation and transport is an important component of biogeochemical carbon cycling in aquatic sediments. To improve understanding how sediment mechanical properties influence growth freshwater sediments, a 20-day laboratory incubation experiment using homogenized natural clay sand was performed. development at high resolution characterized by μCT. Initially, capillary invasion microbubbles (<0.1 mm) dominated formation, with continued gas production (4 days for clay; 8 sand),...
Abstract Estuaries play an important role in the global nitrous oxide budget. However, considerable uncertainties exist estimating their emissions, largely due to anthropogenic impacts, particularly wastewater discharge. Here we investigate emission dynamics Pearl River Estuary through advanced high-resolution, real-time measurements. Results suggest that is a strong source (1.05 Gg yr −1 ; range: 0.92–1.23 ) with pronounced spatial heterogeneity. Wastewater discharge substantially impacts...
Two diel field campaigns under different weather patterns were carried out in the summer and autumn of 2013 to measure CO2 CH4 fluxes probe rates gas exchange across air–water interface a subtropical eutrophic pond China. Bubble emissions accounted for 99.7 91.67% total emission measured at two sites summer; however, no bubble was observed autumn. The supersaturated with during monitoring period, saturation ratios (i.e. concentration/equilibrium concentration) much higher than that CO2....
Three diel field campaigns and one monthly sampling campaign during June 2010-May 2011 were carried out to investigate the CH4 flux across water-gas interface in Xiangxi Bay of Gorges Reservoir, China. The average was much less than that reported from reservoirs tropic temperate regions. photosynthesis phytoplankton dominated gas fluxes alga bloom spring summer. maximum occurred 2010 corresponded lowest water level. Water temperature, sediment temperature TOC did not have significant...
Abstract. Biogenic greenhouse gas emissions, e.g., of methane (CH4) and carbon dioxide (CO2) from inland waters, contribute substantially to global warming. In aquatic systems, dissolved gases are highly heterogeneous in both space time. To better understand the biological physical processes that affect sources sinks CH4 CO2, their concentrations need be measured with high spatial temporal resolution. achieve this goal, we developed Fast-Response Automated Gas Equilibrator (FaRAGE) for...
To discuss the causes and characteristics of occasional severe winter pollution in Wuhan, Hubei Province, China amidst continuous improvement atmospheric environment, this research utilizes air quality monitoring data from various cities Province during winters 2015–2023, analyzing changes using PM2.5 concentration values as an indicator. We employ Convergent Cross Mapping (CCM) method, Wuhan other examples, to reveal causal impact within on a causality perspective. The results indicate...
Estuaries play a crucial role in the global nitrous oxide (N2O) budget, but significant uncertainties remain estimating their emissions due to anthropogenic impacts, particularly wastewater discharge. Using advanced high-resolution, real-time measurements, this study reveals that Pearl River Estuary is substantial N2O emission source, estimated at 1.05 Gg yr-1 (range: 0.92-1.23 yr-1) with pronounced spatial heterogeneity. Wastewater discharge significantly enhances by introducing abundant...
