Hydrogen Sulfide Flux Measurements And Dispersion Modeling From Constr
… gas emission rates from landfills is the flux chamber method. Typically the flux chamber is a cylindrical enclosure device with a spherical top which limits the gas emission area. Pure zero grade air is introduced into the chamber, allowed to mix with emitting gases captured from the …

Metal fluxes across the sediment water interface in a drinking water reservoir
… into the water column, I conducted sediment flux chamber experiments to directly quantify Fe and Mn fluxes at the sediment-water interface of a small, eutrophic drinking water reservoir (Falling Creek Reservoir, Vinton, VA). The experiments were conducted twice during the 2018 summer …

Mercury air surface exchange flux: A field study in the Bay Saint-Francois wetlands, Quebec, Canada.
… of the study was about atmospheric Hg exchange fluxes with water, soil and vegetation on water. Mercury air-surface exchanges with these compartments were measured using a dynamic flux chamber coupled with a Tekran RTM analyzer. Mercury flux measured over these components exhibits a consistently …

Field Emissions of Methane and Nitrous Oxide from California Landfills
… for extensive ground testing using the static flux chamber method, conducted over a year-long time period. At the five sites for ground testing, between five and seven cover systems were tested at each site during the wet and dry season. Daily, intermediate, and final covers were tested to …

Ground vegetation gross primary production dynamics of a drained peatland forest ecosystem
… is another relevant component concerning C fluxes between the land and the atmosphere. Thus, to explore ground vegetation gross primary production (GPPGV) dynamics, its affecting factors, and impacts of the partial harvest; forest floor net exchange (NEFF) and respiration (RFF) were measured …

Direct Volatilization of Naphthalene at a Creosote-Contaminated Site with a Phytoremediation System
… influence this direct volatilization. A flux chamber was designed and constructed to measure naphthalene fluxes from the soil. Factors that influence direct volatilization include the groundwater level, soil moisture, precipitation, pressure changes, temperature and humidity, the most …

Gas Exchange Of Hg Over Wetlands, Effect Of Biochar And Activated Carbon On Hg Emissions From Soil, And Seasonal Concentrations Of Hg In Rain
… cycling of Hg, we investigated Hg0 fluxes over natural wetlands (Sky Lake) and artificial wetlands (UM Field Station) using a dynamic flux chamber and an Hg vapor analyzer based on atomic fluorescence (Chapter 1). We also examined the effect of activated carbon and biochar on Hg …
