Abstract

peer reviewedMore than 600 measurements of carbon dioxide in cave air in Belgium lead to the conclusion that the main factors of its distribution are: (1) a flow originating from the biomass and diffusing in the soil and the voids of bedrock; (2) a trend to go down by density; (3) in some caves, draughts caused, for instance, by a swift underground stream. Results in Belgium are compared to other countries. l'usage d'un masque absorbant le CO2Special attention is paid to human contamination and the use of a CO2-absorbing mask in defined situations is stressed.Plus de 600 mesures du CO2 dans l'air des grottes de Belgique conduisent à la conclusion que les principaux facteurs de sa distribution sont: (1) un flux venant de la biomasse et dif...
