3.   Ozone is a highly reactive form of oxygen gas.

4.   High-altitude ozone is a heavy form of oxygen gas that protects animal and plant life from harmful solar rays.

5.   Instead, Pantano has proposed bathing the flowers in a charged stream of oxygen gas that combines with the organic matter in dust to produce carbon dioxide and steam.

6.   NO The inhalation of pure oxygen gas has been proven beneficial in humans suffering from illnesses that compromise the function of lungs and the cardiovascular system.

7.   One is to bathe the models in a charged oxygen gas that would react with the organic dirt, creating a harmless cloud of carbon dioxide and steam.
