The reason health concerns focus on the indoor environment, is that in some buildings with moisture problems, large numbers of molds may grow far larger than the number growing in the same space outdoors. Furthermore, many buildings have limited air circulation, leading to buildup of high concentrations of spores in some areas. A great deal of research has been conducted on ozone devices being used in occupied spaces to date all indicating that this isn't the control strategy to be used. Some ozone generators may produce high enough concentrations of ozone to cause asthma attacks in children. There is limited research on long term effects of exposures to toxigenic molds.
Many people find relief of their symptoms immediately after the exposure stops.
Thank you to all of those in our chat room who have asked such great questions, and we hope you've received some helpful information - even if your specific question was not addressed. And thank you, Dr. Etzel, Dr. Shaughnessy, Dr. Stahl and Mr. Cross, for joining us tonight and answering our questions. In a majority of these cases, schools are deeply concerned about the problems that exist. Parents and communities need to find ways to fund programs that better address the problems. People should remember that a law suit may NOT necessarily be the best course of action for your lives.
