title: [The depletion of chemical disinfectants during their use (local consumption)].
abstract: The concentration of chemical disinfectants decreases in the contact volume, where bacteria and the chemical disinfectant meet. This can be described quantitatively if one assumes that the latter is consumed in proportion to the number of bacteria killed. The local consumption is controlled by diffusion and hence depends on the thickness of the contact volume which determines the concentration gradient. Local consumption may drastically affect quantitative tests of chemical disinfectants if no precaution is taken.
