Barium Chloride Dihydrate
NATIONAL TOXICOLOGY PROGRAM Technical Report Series No. 432 TOXICOLOGY AND CARCINOGENESIS STUDIES OF BARIUM CHLORIDE DIHYDRATE (CAS NO. 10326-27-9) IN F344/N RATS AND B6C3Fl MICE (DRINKING WATER STUDIES) U.S. DEPARTMENT OF HEALTE AND HUMAN SERVICES Public Health Service National Institutes of Health FOREWORD The National Toxicology Program (NTP) is made up of four charter agencies of the U.S. Department of Health and Human Services (DHHS): the National Cancer Institute (NCI), National Institutes of Health; the National Institute of Environmental Health Sciences (NIEHS), National Institutes of Health; the National Center for Toxicological Research (NCTR), Food and Drug Administration; and the National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control. In July 1981, the Carcinogenesis Bioassay Testing Program, NCI, was transferred to the NIEHS. The NTP coordinates the relevant programs, staff, and resources from these Public Health Service agencies relating to basic and applied research and to biological assay development and validation. The NTP develops, evaluates, and disseminates scientific information about potentially toxic and hazardous chemicals. This knowledge is used for protecting the health of the American people and for the primary prevention of disease. The studies described in this Technical Report were performed under the direction of the NIEHS and were conducted in compliance with NTP laboratory health and safety requirements and must meet or exceed all applicable federal, state, and local health and safety regulations. Animal care and use were in accordance with the Public Health Service Policy on Humane Care and Useof Animals. The prechronic and chronic studies were conducted in compliancewith Food and Drug Administration(FDA) Good Laboratory Practice Regulations, and all aspects of the chronic studies were subjectedto retrospective quality assurance audits before being presented for public review. -

The first version, prepared by the United Nations Economic and Social Council's Committee of Experts on the Transport of Dangerous Goods, was published in 1956 (ST/ECA/43-E/CN.2/170). In response to developments in technology and the changing needs of users, they have been regularly amended and updated at succeeding sessions of the Committee of Experts pursuant to Resolution 645 G (XXIII) of 26 April 1957 of the Economic and Social Council and subsequent resolutions. -
RFC: IRIS Barium and Compounds Substance File
October 29, 2002 Information Quality Guidelines Staff Mail Code 28221T U.S. EPA 1200 Pennsylvania Ave., N.W. Washington, DC, 20460 Subject: Request for Correction of the IRIS Barium and Compounds substance file - Information disseminated by EPA that does not comply with EPA or OMB Information Quality Guidelines Dear Madam or Sir; Chemical Products Corporation (CPC), a Georgia corporation which produces Barium and Strontium chemicals at its Cartersville, Georgia facility, hereby submits this Request for Correction (RFC) concerning EPA’s Integrated Risk Information System Barium and Compounds Substance File (IRIS Ba File). The influential information contained in this file fails to comply with the OMB “Guidelines for Ensuring and Maximizing the Quality, Objectivity, Utility, and Integrity of Information Disseminated by Federal Agencies”. The information disseminated in EPA’s IRIS Barium and Compounds file directly contradicts the information published by EPA in the January 3, 1997 Federal Register and, therefore, cannot represent an EPA consensus position. The IRIS Ba File was revised in 1998 and 1999, yet it contains no mention of the toxicological evaluation conducted by EPA’s Office of Pollution, Pesticides, and Toxic Substances reported in 62 FR 366-372 (No. 2, January 3, 1997). There is no explanation of how a radically different interpretation of the same data could be justified. The NOAEL employed to calculate the Oral Reference Dose in the IRIS Ba File is 0.21 mg/kg/day; there is no LOAEL associated with this NOAEL. The NOAEL reported in 62 FR 366-372 is 70 mg/kg/day in rats and 165 mg/kg/day in mice; these values are taken from a National Toxicology Program technical report and are associated with a LOAEL of 180 mg/kg/day. -

Study of Various Aqueous and Non-Aqueous Amine Blends for Hydrogen Sulfide Removal from Natural Gas
processes Article Study of Various Aqueous and Non-Aqueous Amine Blends for Hydrogen Sulfide Removal from Natural Gas Usman Shoukat , Diego D. D. Pinto and Hanna K. Knuutila * Department of Chemical Engineering, Norwegian University of Science and Technology (NTNU), 7491 Trondheim, Norway; [email protected] (U.S.); [email protected] (D.D.D.P.) * Correspondence: [email protected] Received: 8 February 2019; Accepted: 8 March 2019; Published: 15 March 2019 Abstract: Various novel amine solutions both in aqueous and non-aqueous [monoethylene glycol (MEG)/triethylene glycol(TEG)] forms have been studied for hydrogen sulfide (H2S) absorption. The study was conducted in a custom build experimental setup at temperatures relevant to subsea operation conditions and atmospheric pressure. Liquid phase absorbed H2S, and amine concentrations were measured analytically to calculate H2S loading (mole of H2S/mole of amine). Maximum achieved H2S loadings as the function of pKa, gas partial pressure, temperature and amine concentration are presented. Effects of solvent type on absorbed H2S have also been discussed. Several new solvents showed higher H2S loading as compared to aqueous N-Methyldiethanolamine (MDEA) solution which is the current industrial benchmark compound for selective H2S removal in natural gas sweetening process. Keywords: H2S absorption; amine solutions; glycols; desulfurization; aqueous and non-aqueous solutions 1. Introduction Natural gas is considered one of the cleanest forms of fossil fuel. Its usage in industrial processes and human activities is increasing worldwide, providing 23.4% of total world energy requirement in 2017 [1]. Natural gas is half of the price of crude oil and produces 29% less carbon dioxide than oil per unit of energy output [2]. -
