Classes of contaminants		Brownfields Profile Glossary	Glossary and Key Word List	Definition: Classes of contaminants indicates which categories of contaminants have been identified through the assessment activities. Includes each and every class of contaminants that have been detected. The eight specific classes listed are defined below. To the extent available, the Chemical Abstract Services (CAS) numbers are also provided below. If contaminants are identified that do not fall into one or more of these classes, they are indicated as "other."
Contaminants		RCRA Orientation Manual 2008 Glossary	Glossary and Key Word List	Definition: Any element, substance, compound, or mixture that, after release into the environment and upon exposure, ingestion, inhalation, or assimilation into any organism, will or may reasonably be anticipated to cause illness, death, or deformation in any organism.
