References & Citations On Ozone Gas Hazards, Ozone Generators & Control of Odors and Mold Removal in Buildings

- Technical references, citations, studies on Ozone gas
- The effects of using ozone in buildings to "purify air" or to "kill mold"
- The toxicity of ozone gas and ozone gas exposure limits
- The hazards of ozone generators in buildings
Ozone is widely promoted by ozone generating equipment companies and cleaning services for use in indoor building environments to deodorize, disinfect, "kill" mold, and for "general health". Ozone generators are also promoted for use to reduce the level of airborne particles, pollen, animal dander, and allergens, ostensibly to improve indoor air quality for asthmatics and people with allergies.
While there are some important uses of ozone (such as for medical disinfection under controlled conditions), in general this is an idea which ranges from bad to dangerous in the home.
This article explains the effects of using ozone in buildings for these purposes and warns consumers about misapplication of and health risks from ozone in buildings.
Because at least some of these claims are based on marketing desire, not good science, and because ozone exposure can be both dangerous and ineffective indoors, I have collected some information and references on this topic. © Copyright 2009 Daniel Friedman, All Rights Reserved.
