(Co-Principal Investigator) Integrated Laboratory Systems P.O. Box 13501 Research Triangle Park, North Carolina 27709 October 2001 Toxicological Summary for Sodium Hexafluorosilicate [16893-85-9] and Fluorosilicic Acid [16961-83-4] 10/01 Executive Summary Nomination Sodium hexafluorosilicate and fluorosilicic acid were nominated for toxicological testing based on their widespread use in water fluoridation and concerns that if they are not completely dissociated to silica and fluoride in water that persons drinking fluoridated water may be exposed to compounds that have not been thoroughly tested for toxicity. Nontoxicological Data Analysis and Physical-Chemical Properties Analytical methods for sodium hexafluorosilicate include the lead chlorofluoride method (for total fluorine) and an ion-specific electrode procedure. The percentage of fluorosilicic acid content for water supply service application can be determined by the specific-gravity method and the hydrogen titration method. The American Water Works Association (AWWA) has specified that fluorosilicic acid contain 20 to 30% active ingredient, a maximum of 1% hydrofluoric acid, a maximum of 200 mg/kg heavy metals (as lead), and no amounts of soluble mineral or organic substance capable of causing health effects. -

5.157 TABLE 5.29 Van Der Waals' Constants for Gases the Van Der
DEAN #37261 (McGHP) RIGHT INTERACTIVE top of rh PHYSICAL PROPERTIES 5.157 base of rh cap height TABLE 5.29 Van der Waals’ Constants for Gases base of text The van der Waals’ equation of state for a real gas is: na2 ͩͪP ϩ (V Ϫ nb) ϭ nRT for n moles V2 where P is the pressure, V the volume (in liters per mole ϭ 0.001 m3 per mole in the SI system), T the temperature (in degrees Kelvin), n the amount of substance (in moles), and R the gas constant. To use the values of a and b in the table, P must be expressed in the same units as in the gas constant. Thus, the pressure of a standard atmosphere may be expressed in the SI system as follows: 1 atm ϭ 101,325 N · mϪ2 ϭ 101,325 Pa ϭ 1.01325 bar The appropriate value for the gas constant is: 0.083 144 1 L · bar · KϪ1 · molϪ1 or 0.082 056 L · atm · KϪ1 · molϪ1 The van der Waals’ constants are related to the critical temperature and pressure, tc and Pc, in Table 6.5 by: 27 RT22 RT a ϭ ccand b ϭ 64 Pcc8 P Substance a,L2 · bar · molϪ2 b,L·molϪ1 Acetaldehyde 11.37 0.08695 Acetic acid 17.71 0.1065 Acetic anhydride 26.8 0.157 Acetone 16.02 0.1124 Acetonitrile 17.89 0.1169 Acetyl chloride 12.80 0.08979 Acetylene 4.516 0.05218 Acrylic acid 19.45 0.1127 Acrylonitrile 18.37 0.1222 Allene 8.235 0.07467 Allyl alcohol 15.17 0.1036 Aluminum trichloride 42.63 0.2450 2-Aminoethanol 7.616 0.0431 Ammonia 4.225 0.03713 Ammonium chloride 2.380 0.00734 Aniline 29.14 0.1486 Antimony tribromide 42.08 0.1658 Argon 1.355 0.03201 Arsenic trichloride 17.23 0.1039 Arsine 6.327 0.06048 Benzaldehyde 30.30 0.1553 Benzene 18.82 -

Fact Sheet on Fluoridation Products and Fluoride
Published January 14, 2019 Fact Sheet on Fluoridation Products and Fluoride Background NSF International (www.nsf.org) is an independent, global not-for-profit organization that facilitates standards development, and tests and certifies products for the food, water, health sciences and consumer goods industries to minimize adverse health effects and protect the environment. Founded in 1944, NSF is committed to protecting human health and safety worldwide. NSF International is a Pan American Health Organization/World Health Organization (WHO) Collaborating Center on Food Safety, Water Quality and Indoor Environment. NSF/ANSI 60 NSF/ANSI 60: Drinking Water Treatment Chemicals - Health Effects was developed to establish minimum requirements for the control of potential adverse human health effects from products added directly to water during its treatment, storage and distribution. The standard requires a full formulation disclosure of each chemical ingredient in a product to allow for a comprehensive evaluation of the products and their ingredients. The standard requires testing of the treatment chemical products, typically by dosing these in water at 10 times the maximum use level (MUL), so that trace levels of contaminants can be detected. A further evaluation of test results is required to determine if the concentrations of any detected contaminants have the potential to cause adverse human health effects. When health effects criteria have not been established for a given product or contaminant, the standard requires that health effects criteria be derived according to the requirements of Annex A prior to approval under this standard. For More Information on NSF/ANSI 60… Product Certification NSF’s testing and certification program for drinking water treatment products was developed in the late 1980s to ensure that individual U.S. -

4. Chemical and Physical Information
FLUORIDES, HYDROGEN FLUORIDE, AND FLUORINE 187 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY The common synonyms and other information for fluorine, hydrogen fluoride, sodium fluoride, fluorosilicic acid, and sodium fluorosilicate are listed in Table 4-1. The terms “fluorine” and “fluoride” are often used interchangeably in the literature as generic terms. In this document, we will use “fluoride” as a general term to refer to all combined forms of fluorine unless the particular compound or form is known and there is a reason for referring to it. The term “fluorine gas” will sometimes be used to emphasize the fact that we are referring to the elemental form of fluorine rather than a combined form. In general, the differentiation between different ionic and molecular or gaseous and particulate forms of fluorine-containing substances is uncertain and may also be unnecessary. 4.2 PHYSICAL AND CHEMICAL PROPERTIES Fluorine is the lightest member of Group 17 (VIIA) of the periodic table. This group, the halogens, also includes chloride, bromine, and iodine. As with the other halogens, fluorine occurs as a diatomic molecule, F2, in its elemental form. It has only one stable isotope and its valence in all compounds is -1. Fluorine is the most reactive of all the elements, which may be attributed to its large electronegativity (estimated standard potential +2.85 V). It reacts at room temperature or elevated temperatures with all elements other than nitrogen, oxygen, and the lighter noble gases. Fluorine is also notable for its small size; large numbers of fluorine atoms fit around atoms of another element. -

All reported bond distances and angles have been classified as equilibrium (r 0)' average (r,), substitution (r.), or effective (ro) parameters, and have been given a quality rating which is a measure of the parameter uncertainty. The surveyed literature includes work from all of the areas of gas-phase spectroscopy from which precise quantitative struc· tural information can be derived. Introductory material includes definitions of the various types of parameters and a description of the evaluation procedure.
