Regulatorische Informationen	Chemical: Thiosulfuric acid (H2S2O3), calcium salt (1:1)Thiosulfuric acid (H2S2O3), calcium salt (1:1) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Thiosulfuric acid (H2S2O3), calcium salt (1:1) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA).

It is not approved for use as a chemical in its own right.
Gefahrenübersicht	The oral lethal dose for humans of thiosulfate salts is probably 0.5-5 g/kgSodium thiosulfate is toxic by ingestion causing gastrointestinal disturbance[HSDB] May cause irritationIntraperitoneal LD50 (mouse) = 115 mg/kg[MSDSonline] See Ammonium thiosulfate. See Calcium.
FDA-Anforderungen	Manufacturers, packers, and distributors of drug and drug products for human use are responsible for complying with the labeling, certification, and usage requirements as prescribed by the Federal Food, Drug, and Cosmetic Act, as amended (secs 201-902, 52 Stat. 1040 et seq., as amended21 U.S.C. 321-392).
FIFRA-Anforderungen	As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Calcium thiosulfate is found on List D. Case No: 4057Pesticide type: insecticide, fungicide, herbicideCase Status: None of the active ingredients in the case are being supported for reregistration by their registrants. All are unsupported, or some are unsupported and some are cancelled. Cases described as "unsupported" generally are being processed for cancellation.Active ingredient (AI): Calcium thiosulfateData Call-in (DCI) Date(s): 10/13/95AI Status: Registrants of the pesticide have not made or honored a commitment to seek reregistration, conduct the necessary studies, or pay the requisite fees, or they have asked EPA to cancel their product registrations. Unless some other interested party supports them, products containing the pesticide will be cancelled.
