Ozone

     Triatomic oxygen, O3, is most commonly known as ozone.  It has a
resonance structure, and can be drawn in two different ways:
          O=O-                                   O-O=O
     It is a bluish, explosive gas at room temperature, and has a boiling point
of -119°C.  It has a melting point of -193°C, and is a blue liquid.  It's
critical temperature and pressure are -12.1°C and 53.8 atm, respectively.  It
has a pleasant odor in concentrations of less than 2 ppm, and is irritating and
injurious in higher concentrations.  The density of ozone gas is 2.144 g/L, and
the density of ozone as a liquid is 1.614 g/mL.   It is extremely unstable, and
solutions containing ozone explode upon warming.  It is found in varying
proportions on Earth, but it is about 0.05 ppm at sea level.
     Ozone absorbs harmful ultraviolet radiation in the upper atmosphere, and
protects humans from skin cancer.  But ozone is also the main ingredient of smog,
and causes serious health effects and forest and crop damage in the lower
atmosphere.  Ozone is formed through the chemical reaction of volatile organic
compounds and nitrogen dioxide, in the atmosphere, in the presence of sunlight.
This reaction is called a photochemical reaction, because sunlight is required.
The product is known as smog.  The notorious brownish color of smog is due to
nitrogen dioxide of the mixture.  Increased temperature stimulate the reaction,
which is why ozone conditions are worse in the summer.  It is an oxidant,
meaning it takes electrons away from other molecules, and disrupts key
structures in cells by starting chain reactions.
     Ozone is a serious national problem.  Half of the largest urban areas in
the United States exceed the ozone standards.  The worst regions in the US
include California and the Texas Gulf coast, and the northeast and the Chicago-
Milwaukee area during the summer.  The ozone condition varies from year to year,
as the temperature and weather fluctuate.  This fluctuation also occurs
throughout the day, as emissions from morning traffic builds up, the levels rise.
Ozone emissions come from many things, such as automobiles, gas stations, power
plants, dry cleaners, paint shops, chemical manufacturing pants, oil refineries,
and other business that release volatile organic compounds.
     The health effects of ozone are chest pain, coughing, wheezing, lung and
nasal congestion, labored breathing, sore throat, nausea, rapid breathing, and
eye and nose irritation.  The symptoms oc...
