Ozone gas was recently tested by the EPA in conjunction with the Department of Homeland Security to evaluate the effectiveness of ozone inactivating specific anthrax spores. This is potentially very exciting research for the ozone industry. Read excerpt from the EPA website:
Decontamination of Materials with Ozone Gas in the Presence of Vaporous Organic Compounds
Purpose/Objective:
The U.S. Environmental Protection Agency’s (EPA’s) National Homeland Security Research Center (NHSRC) helps to protect human health and the environment from adverse impacts of terrorist acts by carrying out performance tests on homeland security technologies. In previous testing for NHSRC, ozone gas (O3) was used for inactivation of spores of Bacillus anthracis and other organisms. Unsaturated organic compounds are known to react rapidly with O3 to produce highly reactive species (e.g., hydroxyl radicals, OH•) and reaction products (e.g., formaldehyde), both of which may be effective sporicides. Consequently, mixtures of O3 and reactive organic compounds may be more effective sporicides than O3 by itself. This study investigated the effectiveness of O3 combined with a reactive gas phase organic compound for inactivating spores of B. anthracis (Ames) and the surrogate organism Bacillus subtilis on three representative test materials.
In this research ozone showed very promising results. Other gasses were also mixed with the ozone to evaluate synergistic effects of both.
