Abstract |
The Toxic Substances Control Act (TSCA) of 1976 tasks the Environmental Protection Agency to maintain an inventory of chemical substances (with certain exclusions) that are in United States commerce. This Inventory was gathered from reports on substances that were produced or imported in 1975-1978. An updated version of the Inventory, from which the data in these tapes were drawn, was published in October 1985. The TSCA Chemical Substances Inventory: Reissued Inventory Production Information File contains production information for more than 50,000 chemicals. Each segment on the Production File contains data relevant to one submitter, identified by a Manufacturer's ID, for one chemical substance, identified by a CAS Registry Number. The data elements present on the Production File are: CAS Registry Number, Production Volume, Activity, Manufacturer's ID and Processor Activity. The file, with the TSCA Plantside Information, Preferred Name and Synonym files, provides the complete Toxic Substances Control Act Inventory. |
