Abstract (in english)
   Comparing the CO2-peaks at staying of persons in cave with cave drip water chemistry suggests that cave CO2 do not reach the concentrations, at which both the carbonate species in drip water and in cave air are in equilibrium. Under given conditions, the drip waters will continue (1) in further CO2-degassing and (2) in increasing of the current supersaturation. The threshold values, at which water would became aggressive with respect to calcite, log pCO2[soil] about -2, were not reached. Generally, a reversion of speleothem growth into speleothem dissolution by human breath impact is highly improbable; it would need really extreme conditions.
