Document Summary
We live in the troposphere where most of the weather occurs, such as rain, It"s ironic that at ground level, ozone is a health hazard - it is a major. Up in the stratosphere it absorbs some of the potentially harmful ultraviolet constituent of photochemical smog. (uv) radiation from the sun which can cause skin cancer and damage vegetation, among other things. Stratosphere , dissociating (or splitting) oxygen molecules (o 2 ) to atomic oxygen (o). the atomic oxygen quickly combines with other oxygen molecules to form ozone: Dramatic loss of ozone in the lower stratosphere over antarctica was first noticed in the 1970s. Cfcs (chlorofluorocarbons) , but also compounds containing bromine, other related . Cfcs are a common industrial product, used in refrigeration systems, air conditioners, aerosols, solvents and in the production of some types of packaging. nitrogen oxides are a byproduct of combustion processes, e. g, aircraft emissions. Springtime arctic ozone losses in several recent years.
