As carbon dioxide is absorbed by the ocean, the pH, in turn, lowers. II. Introduction. Carbon Dioxide. The average carbon dioxide concentration in Earth''s atmosphere is 330 ppm. Carbon dioxide is released into the air by the burning of coal, oil, natural gas, or any fossil fuel. In our atmosphere, carbon dioxide levels rise 1 ppm per year on average.

A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2). It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chambers. Carbon dioxide scrubbers are also used in controlled atmosphere (CA) storage.
