GLOSSARY

Ambient:
Surrounding. For example, ambient air is usually outdoor air (as opposed to indoor air).


Carcinogen:
A substance that may cause cancer.


Comparison Value:
Estimated chemical concentrations in specific environmental media that are not likely to cause adverse health effects considering exposure for a specified duration. The comparison values are calculated from scientific literature available on exposure and health effects. The Agency for Toxic Substances and Disease Registry, Environmental Protection Agency, and many state governments have calculated comparison values to use for health assessments and risk assessments.


Concentration:
The amount of a specified substance in a specific medium such as air or water.


Contaminant:
Any substance of material that enters a system (the environment, human body, food, etc.) where it is normally not found.


Dose:
The amount of a substance to which a person is exposed.


Exposure:
Contact with a chemical by swallowing, breathing, or direct contact (with skin or eyes). Exposure may be short term or long term.


Ingestion:
The act of swallowing such as when drinking or eating.


Inhalation:
The act of breathing. Exposure to a hazardous substance may occur from inhaling contaminants in the air. These contaminants can enter the bloodstream or get into the lungs or both.


Media (Environmental):
Environmental media are the specific parts that make up the environment, such as soil, sediment, water, and air, that could contain contamination.


No Apparent Public Health Hazard:
A category applied to sites where human exposure to contaminated media is occurring or has occurred in the past, but the exposure is below a level of health hazard.


Petitioned Public Health Assessment:
A public health assessment conducted at the request of a member of the public. When a petition is received, a team of environmental and health scientists is assigned to gather information to determine, using standard public health criteria, whether there is a reasonable basis for conducting a public health assessment. Once ATSDR confirms that a public health assessment is needed, the process for a petitioned public health assessment is essentially the same as for any other public health assessment.


Public Health Assessment:
A document that includes an evaluation of environmental data and information on the release of hazardous substances into the environment in order to assess any current of future impact on public health, to develop health advisories or to make other recommendations to determine if adverse health effects are associated with the environmental contamination.
