Rapid methane oxidation in a landfill cover soil.
Methane oxidation rates observed in a topsoil covering a retired landfill are the highest reported (45 g m day) for any environment. This microbial community had the capacity to rapidly oxidize CH(4) at concentrations ranging from <1 ppm (microliters per liter) (first-order rate constant [k] = -0.54 h) to >10 ppm (k = -2.37 h). The physiological characteristics of a methanotroph isolated from t...
متن کاملLimits and dynamics of methane oxidation in landfill cover soils.
In order to understand the limits and dynamics of methane (CH(4)) oxidation in landfill cover soils, we investigated CH(4) oxidation in daily, intermediate, and final cover soils from two California landfills as a function of temperature, soil moisture and CO(2) concentration. The results indicate a significant difference between the observed soil CH(4) oxidation at field sampled conditions com...
متن کاملModeling of Methane Migration and Oxidation in Biochar-amended Landfill Cover Soil
The global warming potential (GWP) of methane (CH4) is 25 times the GWP of carbon dioxide (CO2); as such, controlling CH4 emissions at municipal solid waste (MSW) landfills is an urgent task. Oxidation of CH4 using soil covers and bio-enhanced covers as a CH4 mitigation strategy is receiving great attention from environmental professionals. Biochar-amended soil covers are proposed to effectivel...
متن کاملAnaerobic methane oxidation and denitrification as methane sink
Early social exposure is important for developing appropriate, species-specific adult behaviors. Carson Murray et al. (pp. 18189–18194) followed wild chimpanzees, habituated to human observers, in Gombe National Park, Tanzania, and analyzed maternal subgrouping patterns to investigate why adult males tend to be more gregarious than adult females. Mothers accompanied by their sons were more greg...
متن کاملEffect of land use on methane flux from soil.
The precise effects of natural and disturbed terrestrial systems on the atmospheric CH4 pool are uncertain. This study was conducted to quantify and compare CH4 fluxes from a variety of ecosystems in central Iowa. We investigated agricultural systems under different management practices, a hardwood forest site, native and restored prairies, and a municipal landfill. Flux measurements were obtai...
