Ozone
(O3) (activated oxygen) (trivalent oxygen) is a natural
component of the air we breathe each and every day.
Ozone
is created when oxygen (O2) molecules are split into
two separate atoms by ultraviolet radiation from the
sun, lightning and electric arcs. The freed atoms recombine
in three-atom groups to form cousins of oxygen -- or
ozone (O3).
Most
people associate ozone with either the beleaguered upper
atmospheric filter layer that protects us from solar
radiation or with ground level air pollution. Ozone
is indeed present in smog, because certain processes
that create pollution also produce ozone. As well, sunlight
shining on industrial and automotive pollution makes
oxygen atoms hive off from pollutant molecules, leaving
baddies like nitrous oxide, nitric acid, sulphur dioxide
and carbon monoxide. Meanwhile, the freed oxygen atoms
bond with free oxygen in the air to form ozone.
The highly reactive ozone, in turn, recombines with
these same pollutants and neutralizes them by breaking
them down into water, carbon dioxide, nitrogen, sulphur
and oxygen.
Consequently,
increased pollution results in high ozone levels, but
ozone specifically, is not the culprit. Because ozone
levels have a direct relationship to levels of chemical
pollutants found in smog, it is used as an index to
monitor outdoor air pollution. This is why there is
a misunderstanding in reference to ozone.
Ozone
generation machines, which produce ozone for use as
air and water purification, have many benefits to offer
mankind.
Ozone
is one of the most powerful natural sanitizers and deodorizers
known to science. Ozone (activated oxygen) doesn't merely
mask odors and harmful substances, it seeks out and
eliminates them at their molecular source.
Average
outdoor ozone levels in unpolluted areas are between
.03 and .05 parts-per-million. The highest naturally-occurring
levels are found at seashore, forest and mountain locales
-- places people go to vacation and feel refreshed.
The fresh, invigorating air after a spring electrical
thunderstorm is ozone. So is the smell of air-dried
laundry on a clothes line.
Unfortunately,
ozone is missing in our modern indoor environments,
but pollutants are not. Ozone reacts with the sources
of unpleasant or hazardous indoor odors and chemicals.
Chemical pollutant sources, about 99 percent of which
are made up of "unsaturated" molecules, can
take on additional molecules such as ozone (cigarette
smoke as an example, with its 3,600 plus chemicals).
The reactive ozone molecule soon breaks the pollutants
down into their basic molecular components, thereby
neutralizing them. Having given up its unpaired third
oxygen atom in the process, the ozone molecule itself
becomes plain oxygen again.
For
example; formaldehyde -- found in plywood, cabinets,
furniture, tobacco smoke, office dividers, new carpets,
new drapes, wallpaper, paneling and particle board.
Formaldehyde
+ Ozone ===> Carbon Dioxide + Water + Oxygen
HCHO
+ 2O3 ===> CO2 + H2O + 2O2
Bacteria,
molds and fungi (mildew), which can cause unpleasant
odors, allergic reactions and sometimes disease, are
killed when they react with ozone. As with chemical
pollutants, the outer membranes or shells of these microorganisms
contain receptors that can absorb ozone, which proceeds
to break them down. Without its protective membrane
or shell, the bacterium, mold or fungus dies. Viruses
are also killed by ozone.
Is
ozone safe? Like virtually everything -- even oxygen
-- ozone can be harmful if you're exposed to too much
for too long. As mentioned, natural outdoor ozone levels
in clean environments vary between .03 and .05 parts-per-million.
The Food and Drug Administration (FDA) declares .05
ppm as the safe level for 24-hour-a-day inhalation.
This is a conservative standard, since natural levels
of ozone often reach .065 ppm -- 25 percent higher than
the FDA's "safety" limit. In mountainous areas
at higher altitudes the naturally occurring level of
Ozone can be up to eight times higher than that (including
places with among the highest life expectancy figures
in the world).
Relatively
high levels of Ozone can be safely employed in environments
where people live and work because Ozone is neutralised
immediately upon oxidising harmful chemicals, pollutants
and bacteria. In addition, unutilised Ozone has a half
life of only twenty minutes... so Ozone levels can be
reduced exponentially when required . It is for these
reasons that timer based systems are very effective
for use when higher levels of Ozone are required in
spaces which must subsequently be occupied. Automatically
turning off a very high output Ozone generator an hour
or so before returning results in an environment which
contains a significantly reduced Ozone level (Ozone
level @ 20 minutes = 50% of initial level; Ozone level
@ 40 minutes = 25% of initial level; Ozone level @ 60
minutes = 12.5% of initial level etc.). In addition,
opening a door or window can provide an immediate reduction
in levels.
For
people who suffer from allergies and environmental sensitivities,
or those who just want to freshen up musty, smelly basements;
"ground level" ozone can be a powerful ally.
Ozone
is one of Mother Natures' most potent and effective
air and water purifiers.
