Abstrakt
The chemical elimination of "lampflora" (mosses and algae growing around lights in caves) by hydrogen peroxide was studied. A threshold peroxide concentration in cave environment was found to be 15 vol. %. Such peroxide solution slightly attacks limestoneand sinter surface. Therefore, it is strongly recommended an adding of few limestone fragments into peroxide ten hours before application in order to reach a preliminary saturation with respect to calcite.
