Anthropogenic CO2-flux into cave atmosphere and its environmental impact: A case study in the Cisarska Cave (Moravian Karst, Czech Republic)
Abstract:
The evolution of CO2 levels was studied in the ventilated and unventilated Nagel Dome chamber (the Cisarska Cave) with- and without human presence. Based on a simplified dynamic model and CO2/Rn data (222Rn considered as a conservative tracer), two types of CO2-fluxes into the chamber were distinguished: (1) the natural input of (2-4) x 10- 6[no-break space]m3 s- 1, corresponding to a flux of (8.5-17) x 10- 10[no-break space]m3 m- 2 s- 1 and (2) an anthropogenic input of (0.6-2.5) x 10- 4[no-break space]m3 s- 1, corresponding to an average partial flux of (4.8-7.7) x 10- 6[no-break space]m3 s- 1 person- 1. The chamber ventilation rates were calculated in the range from 0.033 to 0.155[no-break space]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 supersaturation with respect to calcite (dripwater saturation index defined as SIcalcite = aCa2? / 10- 8.4 varied in the range from 0.76 to 0.86). The pCO2[DW] values, however, would easily be exceeded if the period of person stay in the chamber had been slightly extended (from 2.85 to 4[no-break space]h under given conditions). In such case, the dripwater CO2-degassing would be inverted into CO2-dissolution and dripwater supersaturation would decrease. Achieving the threshold values at which water become aggressive to calcite (log pCO2[EK] ~ - 1.99, - 2.02, and - 1.84) would require extreme conditions, e.g., simultaneous presence of 100 persons in the cave chamber for 14[no-break space]h. The study should contribute to a better preservation of cave environment
