A 2005 study of the efficacy of chlorine dioxide gas to counter the growth of sick building syndrome-related fungi was shown to successfully diminish mold growth
In the original study, Stachybotrys chartarum, Chaetomium globosum, Penicillium chrysogenum, and Cladosporium cladosporioides were placed in gas chambers containing chlorine dioxide gas.
When the subject was tested for growth, results showed that chlorine dioxide gas inactivated all organisms with the exception of C. globosum colonies which were inactivated an average of 89%.
Chlorine dioxide was proven to be an effective fumigant. A remaining question is how to best implement this as a practical solution safely in real life situations.
