Ozone
This gas is toxic and a health
hazard when it occurs at ground level (ground level ozone), but high
up in the atmosphere it fills a vital role as a filter
of harmful UV radiation.
Ground-level ozone (also known as tropospheric ozone), is ozone near
the earth's surface.
In the stratosphere, at over ten kilometer´s altitude, ozone
protects against the sun's dangerous ultraviolet rays, but it is
harmful to plants and animals living in the lowest part of the
atmosphere.
Ozone
prevents the photosynthesis from taking place and damages the water
balance of plants, and reacts with the mucous membranes of the
respiratory tracts.
Ground level ozone is for instance formed when sunlight meets
exhaust fumes from cars.
It also
produced in photocopiers.
Ozone is a natural greenhouse gas needed to purify the air at ground
level.
In the photochemical process, for example, when the sun's UV rays
hit oxygen (O2), free oxygen is produced (O), and ozone (O3).
Ozone
oxidizes contaminants very quickly and often breaks them down into
carbon dioxide and water.
The decrease of ozone in the atmosphere (due partly to the increased
industrial emissions) has in recent decades led to the so-called
ozone holes appearing over the earth's polar regions (Arctic and
Antarctic).
Technical use
Ozone is chemically very aggressive and has a relatively high
technical use.
It can be used, for instance, to achieve extremely fast and
effective bleaching of chemical pulp, and for sterilization of
water. One problem with the technological use of ozone is its
instability.
It must therefore be produced on site.
Ozone is sometimes used to remove odors.
Common uses are:
-
Preparation of drugs and synthetic lubricants, where the function of
the ozone is to break the carbon-carbon bonds.
-
Bleaching of pulp and textiles.
-
Disinfection of air and water since the ozone kills mold spores,
bacteria and microorganisms.
-
In many parts of the world use ozone instead of chlorine is used to
purify municipal drinking water.
-
Ozone forms no organic chlorine compounds and is not left in the
water after the cleaning
process.
-
Disinfection of washing in hospitals, medical facilities and in the
food industry.
-
Killing of bacteria, yeast, mold and insects on food
as well as in stores for corn.
-
Elimination of odors in furniture that has survived fires but still
smells of smoke. In such cases a so-called ozone chamber is used.
