34 Facts About Ozone

Ozone, or trioxygen, is an inorganic molecule with the chemical formula.

Ozone is formed from dioxygen by the action of ultraviolet light and electrical discharges within the Earth's atmosphere.

Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as 0.

Ozone is a powerful oxidant and has many industrial and consumer applications related to oxidation.

Beaumont, California had as its official slogan "Beaumont: Zone of Ozone", as evidenced on postcards and Chamber of Commerce letterhead.

Ozone is a colourless or pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, in which it forms a blue solution.

Ozone can be used for combustion reactions and combustible gases; ozone provides higher temperatures than burning in dioxygen.

Ozone can be used to remove iron and manganese from water, forming a precipitate which can be filtered:.

Ozone layer has little effect on the longer UV wavelengths called UV-A, but this radiation does not cause sunburn or direct DNA damage, and while it probably does cause long-term skin damage in certain humans, it is not as dangerous to plants and to the health of surface-dwelling organisms on Earth in general (see ultraviolet for more information on near ultraviolet).

Ozone reacts directly with some hydrocarbons such as aldehydes and thus begins their removal from the air, but the products are themselves key components of smog.

Ozone is created naturally in the Earth's stratosphere, but is created in the troposphere from human efforts.

Ozone cracking used to be a serious problem in car tires, for example, but it is not an issue with modern tires.

Ozone has been shown to affect the respiratory, cardiovascular and central nervous system.

Ozone concentration is measured as a maximum daily mean of 8 hour averages and the target should not be exceeded on more than 25 calendar days per year, starting from January 2010.

Ozone can be present in indoor air pollution, partly as a result of electronic equipment such as photocopiers.

Ozone has been implicated to have an adverse effect on plant growth: ".

Ozone cannot be stored and transported like other industrial gases and must therefore be produced on site.

Ozone cracking is the common mode of failure of elastomer seals like O-rings.
