'Safe' ozone levels unhealthy for some, small study finds

Ozone levels considered safe under current standards can have a negative effect on lung function in healthy people, say U.S. researchers.

The National Ambient Air Quality Standard allows for ozone concentrations of up to 75 parts per billion over an eight-hour period. But a new study "found that 6.6 hours exposure to mean ozone concentrations as low as 70 parts per billion have a significant negative effect on lung function," Edward Schelegle, of the University of California, Davis, said in a news release from the American Thoracic Society.

He and his colleagues studied lung function in 31 healthy nonsmokers who were exposed to ozone concentrations of 60, 70, 80 and 87 parts per billion, or filtered air, while doing moderate exercise. They found that significant decreases in lung function and respiratory symptoms occurred at ozone concentrations of 70 parts per billion or more, beginning after 5.6 hours of exposure.

The study appears in the August 1 issue of the American Journal of Respiratory and Critical Care Medicine.

off a cliff, or safe levels of being trapped underwater. This falls right in with the previously acceptable levels of mercury for the developing brain. See my sig.

The study is great and all for showing the Ozone helps remive toxic crud inside the lungs, but the next step would be to determine if their is any long term damage.

Of course, that is not the purpose of this study. All it does is show that Ozone can affect the crappy scum that builds up in the lungs, which causes sysmptoms.

I use and Ozone generator 24 hours a day, and it only affects me significantly directly after exposure to a dusty, dirty environment, which tells me that I've inhaled a few too many particles that my lungs are going to have to deal with anyway.

This is another study meant to spread Fear Uncertainty and Doubt about the Corporate Profit Killing properties of Ozone.

I'll be happy to volunteer myself to these researchers for tests, but I doubt their Corporate sponsors would actually allow that to ever happen.

Again, irritation and discomfort are not the same as breathing unburnt Hydrocarbons or fine particulates.

As soon a people see through the veil of these so called "Scientific Papers", they'll begin to actually do the research for themselves and see how they've been manipulated for the last 50 years.

This is the same kind of thing they did with Fluoride, only they were able to convince the entire country that Fluoride, a highly toxic compound, was actually good for you.

While they have been successful in keeping Chlorine as the king of the heap disinfectant, all of Europe and Asia have been using Ozone for decades, and just because Corporate owned media refuses to allow the American Public to know that Ozone is widely used everywhere other than the US, doesn't change the facts that nobody ever died as a direct result for Ozone exposure, unless they were already compromisied with reduced lung function. People with reduced lung function of other lung diseases can die from many other stresses as well..

My mom survived TB, and uses Ozone.. She's in her mid 80's and is strong as an OX. Still has a clear, active mind, and despite her age, is more productive then most 20 years olds.

I am unable to review the complete paper online, but I'm going to go over this carefully as soon as I can.
