    Anthropogenic CO2-flux into cave atmosphere and its environmental impact: A case study in the Císařská Cave (Moravian Karst, Czech Republic)

  • Original language description

    The evolution of CO2 levels was studied in the ventilated and unventilated Nagel Dome chamber (the Císařská Cave) with- and without human presence. Based on a simplified dynamic model and CO2/Rn data (222Rn considered as a conservative tracer), two typesof CO2-fluxes into the chamber were distinguished: (1) the natural input of (2-4)x10-6 m3 s-1, corresponding to a flux of (8.5-17)x10-10 m3 m-2 s-1 and (2) an anthropogenic input of (0.6-2.5)x10-4 m3 s-1, corresponding to an average partial flux of (4.8?7.7)x10-6 m3 s-1 person-1. The chamber ventilation rates were calculated in the range from 0.033 to 0.155 h-1. Comparison of the chamber CO2-levels with chamber dripwater chemistry indicates that the peak CO2-concentrations during stay of persons (log pCO2 -2.97, -2.89, and -2.83) do not reach the theoretical values at which dripwater carbonate species and air CO2 are at equilibrium (log pCO2(DW) -2.76 to -2.79). This means that CO2-degassing of the dripwaters will continue, increasing
