Abbreviations - Honeywell AUTOMATIC CONTROL Engineering Manual

Radon: A colorless, odorless, radioactive gas emitted during
the disintegration of radium. Radon can be a serious
indoor air contaminant in building areas which are in
contact with or are penetrated by gases emitted from
radium containing bedrock or building stones.
Respirable Suspended Particles (RSP): Inhalable particulate
matter; particles less than 10 micrometer in diameter.
Sick building: A building in which the IAQ is considered to be
unacceptable to a majority of occupants.
Sick Building Syndrome (SBS): A term used to refer to the
condition in which a majority of building occupants
experience a variety of health and/or comfort effects
linked to time spent in a particular building, but where
no specific illness or causative agent can be identified.
Symptoms often include headaches, eye irritation, and
respiratory irritation.
Sink: A material with the property of absorbing a chemical or
pollutant with the potential of subsequent reemission;
sometimes called a sponge.

INDOOR AIR QUALITY FUNDAMENTALS
Source control: A preventive strategy for reducing airborne
contaminant levels through the removal of the material
or activity generating the pollutants.
Stressor: Any biological, chemical physical psychological, or
social factor that contributes to a complaint.
Threshold: The contaminant dose or exposure level below
which there is no expected significant effect.
Total Volatile Organic Compounds (TVOCs): A measure
representing the sum of all VOCs present in the air.
Toxicity: The nature and degree of a given agent's adverse
effects on living organisms.
Volatile Organic Compound (VOC): One of a class of
chemical components that contain one or more carbon
atoms and are volatile at room temperature and normal
atmospheric pressure. In indoor air, VOCs are
generated by such sources as tobacco smoke, building
products, furnishings, cleaning materials, solvents,
polishes, cosmetics, deodorizers, and office supplies.
