Re: OZONE DIFFERENTIATION

[Guest guest]

The author below is right that ozone generated from air contains hazardous

oxides of nitrogen (often seen in EPA pollution reports as NOX). However,

the cost of using an ozone generator for anything other than specific fine

chemical functions with purified oxygen would be very costly.

But the author is dead wrong in claiming that pure ozone is safe. Check

the OSHA and EPA web sites. Recent EPA ozone non-attainment days were

anything above 120 ppb (that's .00000012% of air), with research suggesting

that should be lowered to 80 ppb. These are levels which can cause lung

damage, regardless of nitrogen oxide levels. The only time ozone is safe is

when used in carefully controlled closed reaction vessels, with no exposure

to humans.

According to H. Banks , P.E., author of the article Indoor Air

Quality- A Different Approach, there is both good and bad ozone. " Most of

the ozone standards were developed before 1950 using ozone generators that

were crude when compared to today equipment. The ozone used for their

experiments was generated from air. Since the primary ingredients of air are

oxygen and nitrogen, when ozone is generated from air, the products are

ozone and nitrous oxides. Both nitrogen pentoxide and nitrous oxide are

toxic to the respiratory system but pure ozone is not; therefore if the

nitrogen products are removed from the ozone, the toxicity would be

eliminated. Ozone made from pure oxygen will produce only ozone and oxygen.

Ozone generated from air is called IMPURE OZONE, but ozone made from oxygen

is called PURE OZONE. "
