Chemical Characterization and Thermal Stressing Studies of Perfluorohexane Fluids for Space-Based Applications
Chemical Characterization and Thermal Stressing Studies of Perfluorohexane Fluids for Space-Based Applications William A. Arnold, Ph.D.1 ZIN Technologies, Inc., Brook Park, Ohio, 44142, USA Thomas G. Hartman, Ph.D.2 CAFT, Cook College, Rutgers the Sate University of New Jersey, New Brunswick, NJ, 08901 USA John McQuillen,3 NASA Glenn Research Center, Cleveland, Ohio, 44135, USA Perfluorohexane (PFH), C6F14, is a perfluorocarbon fluid. Several PFH fluids with different isomer concentrations were evaluated for use in an upcoming NASA space experiment. Samples tested included two commercially obtained high-purity n-perfluorohexane (n-PFH) fluids and a technical grade mixture of C6F14 branched and linear isomers (FC-72). These fluids were evaluated for exact chemical composition, impurity purity and high temperature degradation behavior (pyrolysis). Our investigation involved simulated thermal stressing studies of PFH fluids under conditions likely to occur in the event of an atmospheric breach within the International Space Station (ISS) and subsequent exposure of the vapors to the high temperature and catalyst present in its Trace Contaminant Control Subsystem (TCCS). Exposure to temperatures in the temperature range of 200-450°C in an inert or oxidizing atmosphere, with and without the presence of catalyst was investigated. The most aggressive conditions studied were exposure of PFH vapors to 450°C in air and in the presence of TCCS (palladium) catalyst. Gas chromatography-mass spectrometry (GC-MS) and gas chromatography (GC) analyses were conducted on the perfluorohexane samples before and after pyrolysis. The FC-72 and n-PFH samples showed no significant degradation following pyrolysis even under the most aggressive study conditions. -

Abstract Trihalomethanes (THMs) are disinfection byproducts formed through the reaction of chlorine and organic matter. There are four forms of Trihalomethanes: chloroform, bromoform, dibromochloromethane and bromodichloromethane. Studies have shown that chloroform, a principal disinfection byproduct, is carcinogenic in rodents. Although the presence of these hazardous materials are constantly being monitored by Water Treatment Plant and the Environmental Protection Agency (EPA), they continue to be present at an unpredictable levels and the full effects of these byproducts are not fully understood. -

Toxicological Profile for Bromodichloromethane
BROMODICHLOROMETHANE 89 CHAPTER 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW Bromodichloromethane has been identified in at least 238 of the 1,854 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (ATSDR 2017). However, the number of sites in which bromodichloromethane has been evaluated is not known. The number of sites in each state is shown in Figure 5-1. Of these sites, 233 are located within the United States, 2 are located in the Virgin Islands, and 3 are located in Puerto Rico (not shown). Figure 5-1. Number of NPL Sites with Bromodichloromethane Contamination • The most likely route of exposure for the general public to bromodichloromethane is through ingestion, inhalation, and dermal contact of chlorinated drinking water. • A median bromodichloromethane intake of 2.8–4.2 µg/day from drinking water has been estimated; inhalation and dermal exposure would add to this daily intake. BROMODICHLOROMETHANE 90 5. POTENTIAL FOR HUMAN EXPOSURE • Bromodichloromethane is formed as a byproduct of water disinfection methods using chlorination. This is the primary source of bromodichloromethane in the environment. • Its principal use is as a chemical intermediate for organic synthesis and as a chemical reagent. • Volatilization is an important fate process. Bromodichloromethane evaporates from sources and enters the environment as a gas, which is slowly broken down in air. Residual bromodichloromethane may be broken down slowly by bacteria. • In the atmosphere, bromodichloromethane is thought to undergo slow degradation through oxidative pathways, with a half-life of about 2–3 months. 5.2 PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL 5.2.1 Production The principal anthropogenic source of bromodichloromethane is its unintentional formation as a byproduct during the chlorination of water containing organic materials and bromide. -

Summary of Information for ABC for Polycyclic Aromatic Hydrocarbons
Air Toxics Science Advisory Committee Summary of Information for ABC for Polycyclic Aromatic Hydrocarbons September 16, 2015 ATSAC Meeting #10 Presenter: Sue MacMillan, DEQ ATSAC lead Sue MacMillan | Oregon Department of Environmental Quality 26 Individual PAHs to Serve as Basis of ABC for Total PAHs Acenaphthene Cyclopenta(c,d)pyrene Acenaphthylene Dibenzo(a,h)anthracene Anthracene Dibenzo(a,e)pyrene Anthanthrene Dibenzo(a,h)pyrene Benzo(a)pyrene Dibenzo(a,i)pyrene Naphthalene Benz(a)anthracene Dibenzo(a,l)pyrene has separate Benzo(b)fluoranthene Fluoranthene ABC. Benzo(k)fluoranthene Fluorene Benzo( c)pyrene Indeno(1,2,3-c,d)pyrene Benzo(e)pyrene Phenanthrene Benzo(g,h,i)perylene Pyrene Benzo(j)fluoranthene 5-Methylchrysene Chrysene 6-Nitrochrysene Use of Toxic Equivalency Factors for PAHs • Benzo(a)pyrene serves as the index PAH, and has a documented toxicity value to which other PAHs are adjusted • Other PAHs adjusted using Toxic Equivalency Factors (TEFs), aka Potency Equivalency Factors (PEFs). These values are multipliers and are PAH-specific. • Once all PAH concentrations are adjusted to account for their relative toxicity as compared to BaP, the concentrations are summed • This summed concentration is then compared to the toxicity value for BaP, which is used as the ABC for total PAHs. Source of PEFs for PAHs • EPA provides a range of values of PEFs for each PAH • Original proposal suggested using upper-bound value of each PEF range as the PEF to use for adjustment of our PAHs • Average PEF value for each PAH is a better approximation of central tendency, and is consistent with the use of PEFs by other agencies • Result of using average, rather than upper-bound PEFs: slightly lower summed concentrations for adjusted PAHs, thus less apt to exceed ABC for total PAHs Documents can be provided upon request in an alternate format for individuals with disabilities or in a language other than English for people with limited English skills. -
