ChemID Adds the EPA Master Testing List to SUPERLIST

A new list has been added to the ChemID file regenerated in March of this year. SUPERLIST is the term used in ChemID to designate a collection of lists of chemical substances maintained by key federal and state regulatory agencies, as well as by selected scientific organizations concerned with health and environmental hazards. See the article on pages 25-30 of the July-August 1990 Technical Bulletin for a complete description of SUPERLIST. A list, such as "MTL" (Master Testing List), which is part of SUPERLIST, will contain the value SUPERLIST in the Locator (LO) field and will also have the individual list acronym in the List Locator (LLO) field. For information about SUPERLIST and all the individual lists contained within it, go to the NLM Web site: http://sis.nlm.nih.gov and click on Chemical and Drug Information and then click on Superlist.

Master Testing List

The Master Testing List (SUPERLIST acronym "MTL") is produced by the Environmental Protection Agency (EPA) and lists EPA chemical testing priorities, as well as those of other Federal Agencies, including the Toxic Substances Control Act (TSCA) Interagency Testing Committee and the Organization for Economic Cooperation and Development (OECD). The EPA has determined that the chemicals selected for the MTL present significant potential health and/or environmental concerns and need to be tested. The MTL provides a single designation for what EPA has consolidated into a listing of chemicals being tested for toxicity.

Searching for and Displaying List Information

List information is shown as part of the Name of Substance (NM) field and in the List Locator (LLO) field; both of these fields are displayed with the basic PRINT command. You can see more detailed information obtained from the List source in the Classification Code (CC) field. For MTL List records, testing status information is displayed in the CC field. Enter the command PRINT INCLUDE CC to view this field. See Figure 1 for a sample display of a record containing MTL List information. All records associated with a List name may be retrieved by searching on the List name qualified by LO or LLO, because the LLO field data is also contained in the LO field.
