Footnotes to Data Tables

CAS Number: This number, the Chemical Association Service number, is used by scientists around the world. Each chemical is given a unique number that allows scientist to ensure that they are talking about the same chemical regardless of chemical name.

ND : "Non-Detect" - The laboratory establishes Detection Limits for sampling events for each chemical included in this study. The Detection Limit is the minimum amount that the laboratory could detect accurately. When a data entry contains the non-detect or 'ND' tag, it means the chemical compound in the sample was below the Detection Limit.

NC: "Not Collected" - Indicates that a sample was not collected at a particular date and location.

NA: "Not Available" - Some chemicals do not have established risk-based concentrations. This could be for a variety of reasons. US EPA may not have adequate information about the health effects of the chemical or data are not available to make determinations about cancer risks.

Detection Limit: The lowest amount that can be distinguished from the normal "noise" of an analytical instrument or method as established by the laboratory.

Units: This represents the unit of measure that the chemical concentration is reported in. Four different units of measure are commonly used to represent concentrations of compounds in air:

ppb: Part per billion - One part per billion is 1 part in 1,000,000,000.
ug/scm: Micrograms per standard cubic meter of air - One microgram is 10^-6 of a gram.
ng/scm: Nanograms per standard cubic meter of air – One nanogram is 10^-9 of a gram.
pg/scm: Picograms per standard cubic meter of air – One picogram is 10^-12 of a gram.
