(PAC) Rev 24 Based on Applicable Aegls, Erpgs, Or Teels (Chemicals Listed by CASRN) PAC Rev 24 – August 2008
Table 3: Protective Action Criteria (PAC) Rev 24 based on applicable AEGLs, ERPGs, or TEELs (Chemicals listed By CASRN) PAC Rev 24 – August 2008 Table 3 presents a listing of chemicals and PAC data based on the Chemical Abstract Service Registry Numbers (CASRNs)1 of the chemicals. Chemicals without an identified CASRN number are issued an identification number, preceded by the letter “z,” for purposes of the PAC data set. The columns presented in Table 3 provide the following information: Heading Definition No. The ordered numbering of the chemicals as they appear in this listing by CASRN. Chemical Name The common name of the chemical. CASRN The Chemical Abstract Service Registry Number for this chemical. TEEL-0 This is the threshold concentration below which most people will experience no appreciable risk of health effects. This PAC is always based on TEEL-0 because AEGL-0 or ERPG-0 values do not exist. PAC-1 Based on the applicable AEGL-1, ERPG-1, or TEEL-1 value. PAC-2 Based on the applicable AEGL-2, ERPG-2, or TEEL-2 value. PAC-3 Based on the applicable AEGL-3, ERPG-3, or TEEL-3 value. Units The units for the PAC values (ppm or mg/m3). Additional information on the chemicals presented here is provided in PAC Tables 1, 2, and 4. Table 3, other PAC Tables, introductory/explanatory material (including a glossary of acronyms and abbreviations), definitions of PAC values, and alternative methods of displaying PAC information are available electronically at: http://www.hss.energy.gov/HealthSafety/WSHP/chem_safety/teel.html. -
Zinc Fluoride Product Stewardship Summary February 2011
Zinc Fluoride Product Stewardship Summary February 2011 ZnF2 Chemical Name: Zinc Fluoride Chemical Category (if applicable): Metal Halide Synonyms: Zinc difluoride; ZnF2 CAS Number: 7783-49-5 CAS Name: Zinc fluoride EC (EINECS) Number: 232-001-9 Document Number: GPS0041 V1.0 Zinc fluoride (ZnF2) is used in the manufacture of metals, in fluxes, chemical synthesis, and in the manufacture of special glasses.. Exposure can occur at either a ZnF2 manufacturing facility or at other manufacturing, packaging or storage facilities that handle ZnF2. Persons involved in maintenance, sampling and testing activities, or in the loading and unloading of ZnF2 packages are at risk of exposure, but worker exposure can be controlled with the use of proper general mechanical ventilation and personal protective equipment. Workplace exposure limits for fluoride ion have been established for use in worksite safety programs. When ZnF2 is a component of consumer products, users should follow manufacturer’s use and/or label instructions. ZnF2 dusts released to the atmosphere and deposited in soil or surface water in the vicinity of production sites have negligible impact on the environment. Please see the MSDS for additional information. ZnF2 s a nonflammable solid that is stable under normal conditions. Contact of ZnF2 with water or extended skin contact under moist conditions can produce hydrofluoric acid (HF), a very dangerous acid. Breathing ZnF2 dust can irritate the nose, throat, and lungs. Short-term exposure to high concentrations of ZnF2 may cause nausea, vomiting, loss of appetite and weakness. Long-term exposure to ZnF2 may cause deposits of fluorides in bones and teeth, a condition called fluorosis, which may result in pain, disability and discoloration or mottling of teeth. -
Evaluation of Antibacterial and Cytocompatible Properties Of
Dental Materials Journal 2020; : – Evaluation of antibacterial and cytocompatible properties of multiple-ion releasing zinc-fluoride glass nanoparticles Erika NISHIDA1, Hirofumi MIYAJI1, Kanako SHITOMI1, Tsutomu SUGAYA1 and Tsukasa AKASAKA2 1 Department of Periodontology and Endodontology, Faculty of Dental Medicine, Hokkaido University, N13 W 7, Kita-ku, Sapporo, Hokkaido 060- 8586, Japan 2 Department of Biomedical Materials and Engineering, Faculty of Dental Medicine, Hokkaido University, N13 W 7, Kita-ku, Sapporo, Hokkaido 060- 8586, Japan Corresponding author, Hirofumi MIYAJI; E-mail: [email protected] Zinc-fluoride glass nanoparticles (Zinc-F) release several ions, such as fluoride, zinc and calcium ions, through acid-base reactions. The aim of this study was to evaluate the antibacterial and cytotoxic properties of Zinc-F. Antibacterial tests showed that a Zinc-F eluting solution significantly reduced the turbidity and colony-forming units ofStreptococcus mutans and Actinomyces naeslundii, compared to that of calcium-fluoroaluminosilicate glass nanoparticles without zinc ions. In live/dead staining, Zinc-F eluate significantly decreased green-stained bacterial cells, indicating live cells, compared with the control (no application). Human dentin coated with Zinc-F showed suppressed S. mutans and A. naeslundii biofilm formation. Additionally, Zinc-F eluate showed low cytotoxic effects in osteoblastic and fibroblastic cells. Therefore, our findings suggested that Zinc-F exhibits antibacterial and biocompatible properties through multiple-ion release. Keywords: Actinomyces naeslundii, Biocompatibility, Dentin, Streptococcus mutans, Zinc-fluoride glass nanoparticles calcium and silicon and a phosphoric acid solution. It is INTRODUCTION assumed that Zinc-F aggregates on the dentin surface to Root caries has become a major problem in elderly close dentinal tubules and release zinc, fluoride, calcium people with exposed tooth roots caused by aging or and silicon ions through acid-base reactions, such as periodontal disease. -
Appendix H EPA Hazardous Waste Law
Appendix H EPA Hazardous Waste Law This Appendix is intended to give you background information on hazardous waste laws and how they apply to you. For most U.S. Environmental Protection Agency (EPA) requirements that apply to the University, the Safety Department maintains compliance through internal inspections, record keeping and proper disposal. In Wisconsin, the Department of Natural Resources (DNR) has adopted the EPA regulations, consequently EPA and DNR regulations are nearly identical. EPA defines This Appendix only deals with "hazardous waste" as defined by the EPA. hazardous waste as Legally, EPA defines hazardous waste as certain hazardous chemical waste. This hazardous chemical Appendix does not address other types of regulated laboratory wastes, such as waste; radioactive, infectious, biological, radioactive or sharps. Chapter 8 descibes disposal procedures infectious and biohazardous waste for animals. Chapter 9 describes disposal procedures for sharps and other waste that are regulated by can puncture tissue. Chapter 11 discusses Radiation and the Radiation Safety for other agencies. Radiation Workers provides guidelines for the disposal of radioactive waste. Procedures for medical waste are written by the UW Hospital Safety Officer. The Office of Biological Safety can provide guidance for the disposal of infectious and biological waste. EPA regulations focus on industrial waste streams. As a result, many laboratory chemical wastes are not regulated by EPA as hazardous chemical waste. However, many unregulated chemical wastes do merit special handling and disposal If a waste can be procedures. Thus, Chapter 7 and Appendix A of this Guide recommend disposal defined as: procedures for many unregulated wastes as if they were EPA hazardous waste. -
