(1) High in the atmosphere this is not a problem as ozone blocks the harmful rays from the sun.(2) Although CO2 is by far the most well known green house gas, we humans also produce others in the form of methane, CFC's, ozone and nitrous oxide.(3) Even though it's made of only three little molecules of oxygen, ozone can be a pretty big topic.(4) The four usual agents of deterioration in the air apart from oxygen and water are sulphur dioxide, hydrogen sulphide, ozone and nitrogen dioxide.(5) Public water systems treat water with chlorine, ultraviolet light or ozone to kill E. coli.(6) So, as we learn more about stratospheric ozone and climate change, what were once two separate problems have become more and more entwined.(7) Because of wind patterns, most ozone blows east to Fountain Hills.(8) In the upper atmosphere, or the stratosphere, ozone is very good, as it acts as a shield to protect life on Earth from harmful Ultraviolet sunlight.(9) Nitrogen Oxides, primarily from automobile exhaust, ramp up ozone production to toxic levels.(10) Standard vertical profiles of pressure, temperature, relative humidity and ozone density are selected, according to the U.S. Standard Atmosphere.(11) No one disputes that stratospheric ozone recovery is one of the environmental movement's great success stories.(12) Tropospheric ozone can permanently damage people's lungs and prohibit plants from producing and storing food.(13) Carbon monoxide is not only a hazardous air pollutant itself, it is also a chemical compound that produces ozone , a greenhouse gas that is a human health hazard.(14) Already used to control bacteria in some pools and aquariums, ozone gas causes oxidizing reactions that damage tissue.(15) Part I of The Ozone Layer relates the history of our understanding of stratospheric ozone .(16) Water vapour, carbon dioxide, ozone , methane, nitrous oxide, and the chlorofluorocarbons are known as Greenhouse Gases.
