Atmospheric CO2 Concentrations in Caves Protected as Nature Reserves and Related Gas Hazard
نویسندگان
چکیده
Atmospheric CO2 concentrations can reach high levels inside natural caves, representing a hazardous condition for both humans frequenting the underground environment and its safeguard due to corrosion of speleothems induced by acidification atmospheric moisture. These issues are particularly critical eco-sustainable management caves protected as nature reserves undergoing touristic exploitation. In this paper we present results C6 project, which was activated in 1999 monitoring air quality three Sicily (Italy). Near-real-time spot measurements temperature concentration have been carried out since year 2000, giving opportunity evaluating gas hazard visitors potential impact on environments, well influence meteorological hydrological conditions driving carbon dioxide accumulations. The analysis data acquired hypogeal atmosphere, their comparison with analogous epigeal measures, indicates that accumulation is controlled complex interaction among cave topography, dynamics, gaseous exchanges between groundwaters human fruition. This last factor, under particular conditions, surprisingly diminishing concentrations.

Effects of elevated atmospheric CO2 concentrations on soil microorganisms.
Effects of elevated CO(2) on soil microorganisms are known to be mediated by various interactions with plants, for which such effects are relatively poorly documented. In this review, we summarize and synthesize results from studies assessing impacts of elevated CO(2) on soil ecosystems, focusing primarily on plants and a variety the of microbial processes. The processes considered include chan...
متن کاملMeasuring the Marginal Impact of Co2 Emissions on Atmospheric Concentrations
The response of atmospheric CO2 concentrations to an incremental increase in emissions is usually measured using an impulse response function. These functions are then used in calculating Global Warming Potentials, marginal climate damages, and CO2 timescales. It is shown here that the impulse response method implicitly double counts the effects of emissions on concentration by not properly acc...

A record of atmospheric carbon dioxide (CO2) concentration during the transition from the Last Glacial Maximum to the Holocene, obtained from the Dome Concordia, Antarctica, ice core, reveals that an increase of 76 parts per million by volume occurred over a period of 6000 years in four clearly distinguishable intervals. The close correlation between CO2 concentration and Antarctic temperature ...
