GLI Clearinghouse Chemical and Data Field Lists

Chemical List

The GLI Clearinghouse currently has data on 423 chemical substances, which are listed by:

  • chemical name
  • number, either:
    • Chemical Abstracts Service Registry number (CASRN or CAS number)
    • or EPA Identifier (EPA ID)
      • EPA IDs begin with "E"
      • EPA gives them to substances without a CAS number
  • and systematic name.

To search the list for a specific name or CAS number: once you've opened the spreadsheet, press CTRL+F.

If you don't know the CAS number, you can look it up in EPA's Substance Registry Services.

Data Field Lists

The Clearinghouse provides data only to the extent that they were included in the State/Tribal fact sheets or similar support documents. Therefore, the number of data fields available for a given query varies by both agency and use. The complete set of data fields for each designated use is shown below. If you need more data than what is displayed with a criterion result, view the original source link listed with the criterion result.
