Halocarbons: are chemicals that have been used for a variety of applications, such as refrigerants and fire retardants (such as chlorofluorocarbons (CFCs))  They are potent greenhouse gases. CFCs also damage the ozone layer. The production of most CFCs is now banned, so their concentrations are starting to decline.

Ozone: (O3) Is a kind of oxygen that has three oxygen atoms per molecule instead of two. There are two different types of ozone. Stratospheric ozone, which is produced naturally in the stratosphere (the layer 6 to 30 miles above the Earth's surface) and Tropospheric ozone (or ground-level ozone) which is a noxious pollutant. Stratospheric ozone forms a shield that prevents the sun's harmful ultraviolet rays from reaching the earth's surface.. It has been found that CFCs, HCFCs, and halons deplete the ozone in the stratosphere, causing seasonal holes over the poles, especially the South Pole.
Tropospheric ozone (or ground-level ozone) creates smog, it is formed when volatile organic compounds (VOCs), oxygen and nitrogen oxides react in the presence of sunlight. Though ozone is beneficial in the stratosphere, ground-level ozone is a respiratory irritant and air pollutant.

Early on it was labeled 'objectionably toxic' and PCB production was banned in the U.S. in 1979 and in 2001 by the Stockholm Convention. The only North American producer was Monsanto who produced over 600,000 tons between 1930 and 1977. PCBs are persistent in the environment to this day and accumulate in animal tissue. General Electric released up to 1,300,000 pounds of PCBs into the Hudson River between 1947 and 1977.
