What good things does ozone do?

The ozone in the earth's upper atmospheric, the stratosphere, moderates and reduces ultraviolet light. preventing much of it from getting to the ground level. When this ozone is depleted, more ultraviolet light passes to the ground level.

On one hand, long wave ultraviolet light striking the skin produces natural vitamin D in the body, which helps metabolize calcium into bone tissue. On the other hand, short wave ultraviolet light is ionizing radiation which can produce skin cancer.

It may be that the dosage of ultraviolet light that constitutes benefical exposure, and what constitutes excessive exposure may be overlapping. Both the benefits and risks may be present at the same time. It can be seen that both less ozone and more ozone in the upper atmosphere have detriments and benefits simultaneously.

On the ground level ozone is a respiratory irritant, and can aggravate the respiratory tract and also asthmatic conditions.

Ozone will do everything that oxygen will do, and it will do it eight times faster.

Conventional medicine considers ozone to be an air pollutant and a poisonous gas, and it is a major contributor to the production of smog.

There are some adherents to alternative medicine who claim many "cures" using ozone.

However, there appear to be legitimate medical uses for ozone; see this link:

Other uses

It purifies water--most of the bottled water you see says "purified by ozonation" on it. They use an air stone to bubble ozone through the water, and the ozone kills any organisms that might be living there. Eductors are today more commonly used to apply ozone, since eductors do not provide tiny difficult to clean pores in a drinking water system like diffuser stones do. They also provide the possibility of applying ozone into pressurized systems.

Ozone is applied into sewer manholes, where is dissolves grease (along with water vapor) and destroys odors (however briefly).

Ozone is applied to municipal water (in some cases), where it will destroy pharmaceuticals, destroy taste and odor, make organic molecules easier for activated cabon to destroy, sterilize the water, and act as a flocculant (agglomeration of contaminant molecules that cane settle or filter more easily).
