RSEI Data Dictionary: Elements Data

The following tables provide descriptions for each field in each table. Note that for the Geographic Microdata, "Other Geographies" includes block groups, census tracts, and ZIP code files.  For more information, see the RSEI methodology document and the RSEI Microdata documentation. 

                                                               Tables in the RSEI Data Dictionary
Facility Chemical Disaggregated Grid Cell Geographic Microdata Aggregated Grid Cell Geographic Microdata for States
Off-site MCL Aggregated Grid Cell Geographic Microdata Water Geographic Microdata
Submissions Releases Disaggregated Geographic Microdata for Other Geographies Grid Shapefiles
Elements Media Aggregated Geographic Microdata for Other Geographies Census Crosswalks
NAICS Category Geographic Microdata Shapefiles for Other Geographies Population Data

The Elements table contains the calculated results for each release. There can be multiple elements records for each release. 

The Submission, Releases , and Elements tables are too large for spreadsheet format.

This table is from RSEI Version 2.3.12 (RY 2022) and cannot be used with tables from any other version.

Elements Data

Variable Description
ElementNumber Unique internal identifier.

ReleaseNumber

Unique internal identifier (links to Releases table).
PoundsPT Total pounds after any treatment by POTWs or other offsite facilities.
ScoreCategory Codes corresponding to the medium into which the chemical is released. Examples of the information include: direct air releases from the stack using a “rural” air dispersion model, fugitive air releases, releases to an onsite landfill. [See Category table for descriptions]
Score
(RSEI Score)
Total Indicator Element score- modeled surrogate dose multiplied by toxicity weight and by population, using the higher cancer/noncancer toxicity weight for each air/water pathway.
Population Total population exposed.
ScoreA Score for children 0 through 9 years of age (inclusive).
PopA Number of exposed children 0 through 9 years of age (inclusive).
ScoreB Score for children 10 through 17 years of age (inclusive).
PopB Number of exposed children 10 through 17 years of age (inclusive).
ScoreC Score for adults 18 through 44 years of age (inclusive).
PopC Number of exposed adults 18 through 44 years of age (inclusive).
ScoreD Score for adults 45 through 64 years of age (inclusive).
PopD Number of exposed adults 45 through 64 years of age (inclusive).
ScoreE Score for adults 65 years old and greater.
PopE Number of exposed adults 65 years old and greater.
NCScore (Noncancer Score) Indicator Element score, limited to chemicals with non-cancer endpoints.
CScore (Cancer Score) Indicator Element score, limited to chemicals with cancer endpoints.
Hazard
(RSEI Hazard)
Toxicity weight times PoundsPT, using the higher cancer/noncancer toxicity weight for each air/water pathway.
HazardC
(Cancer Hazard)
Toxicity weight times PoundsPT, limited to chemicals with cancer endpoints.
HazardNC
(Noncancer Hazard)
Toxicity weight times PoundsPT, limited to chemicals with non-cancer endpoints.
