Evaluation of the effectiveness of gaseous chlorine dioxide.
Int J Occup Environ Health 2009 Apr; 15(2):230
The HHE Program responded to a management request from an urban rehabilitation company. The request concerned evaluating the effectiveness of using gaseous chlorine dioxide (CIO2) treatments to reduce microbial contamination in a house under renovation. HHE Program investigators collected air samples, sticky tape samples from surfaces, and wipe samples before and after CIO2 treatment. Investigators found that culturable bacteria and fungi concentrations were significantly decreased after the CIO2 treatment. There were no significant differences in airborne endotoxin and beta-glucan concentrations before and after CIO2 treatment. Investigators also found that microscopic analyses of tape samples collected after treatment showed that fungal structures were still present on surfaces. HHE Program investigators recommended that managers use additional cleanup techniques, such as using high efficiency particle air filter vacuums in order to reduce concentrations of spores and microbial components before re-occupancy is permitted.
