A method for determining exposure of a test sample to hydrogen peroxide in an atmosphere includes placing a substrate into the atmosphere, contacting the substrate with the hydrogen peroxide, reacting the hydrogen peroxide with a dye intermediate to produce a chromophore indicative of the integrated exposure of hydrogen peroxide in the atmosphere; and correlating the chromophore to the integrated exposure of hydrogen peroxide in the atmosphere. The dye intermediate may be a dye-couple of 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) and 3-dimethylaminobenzoic acid (DMAB). The intensity of the chromophore is indicative of an integrated hydrogen peroxide exposure.
