Quantitative method to determine sporicidal decontamination of building surfaces by gaseous fumigants, and issues related to laboratory-scale studies

The sporicidal efficacies of the two fumigants, chlorine dioxide gas and vaporous hydrogen peroxide sterilant, on six building structural materials are studied. A high-throughput quantitative method is developed for determining the efficacies of fumigants and the spore recoveries from five porous materials and on nonporous material.
