This publication evaluates possible sources of ambient air contamination and the role of the ASU in controlling and eliminating these contaminants.

The ASU contaminant evaluation includes:

– identifying potential contaminants;

– physical and chemical properties of the contaminants;

– ASU impact on contaminants;

– oxygen concentration factors;

– concentration levels of contaminants remaining in oxygen;

– particulates; and

– conclusions/data evaluation by a third party toxicologist and by industry.
