Exposure Data
BERYLLIUM AND BERYLLIUM eOMPOUNDS Beryllium and beryllium compounds were considered by previous Working Groups, In 1971,1979 and 1987 (lARe, 1972, 1980, 1987a). New data have since become available, and these are included in the present monograph and have been taken into consideration In the evaluation. The agents considered herein Include (a) metallic beryllium, (b) beryllium- aluminium and -copper alloys and (c) some beryllum compounds. 1. Exposure Data 1.1 Chemical and physical data and analysis 1.1.1 Synonyms, trade names and molecular formulae Synonyms, trade names and molecular formulae for beryllium, beryllum-aluminium and -copper alloys and certain beryllium compounds are presented in Thble 1. The list is not exhaustive, nor does it comprise necessarily the most commercially important beryllum- containing substances; rather, it indicates the range of beryllum compounds available. 1. 1.2 Chemical and physical properties of the pure substances Selected chemical and physical properties of beryllium, beryllum-aluminium and -copper alloys and the beryllium compounds covered in this monograph are presented in Thble 2. The French chemist Vauquelin discovered beryllium in 1798 as the oxide, while analysing emerald to prove an analogous composition (Newland, 1984). The metallc element was first isolated in independent experiments by Wöhler (1828) and Bussy (1828), who called it 'glucinium' owing to the sweet taste of its salts; that name is stil used in the French chemical literature. Wöhler's name 'beryllum' was offcially recognized by IUPAe in 1957 (WHO, 1990). The atomic weight and corn mon valence of beryllum were originally the subject of much controversy but were correctly predicted by Mendeleev to be 9 and + 2, respectively (Everest, 1973). -

FEDERAL LAW AND VERTEBRATE PEST CONTROL By: Justus C. Ward, Director, Pesticides Regulation Division, Agricultural Research Service, U.S. Department of Agriculture Presented at the Vertebrate Pest Control Conference, Sacramento, California, February 6 and 7, 1 962 Shortly after the passage of the Federal Insecticide Act of 1910> mammal control specialists in the Bureau of Biological Survey began to consider a similar law to cover the chemicals with which they were concerned. Work on the project went slowly a nd spasmodically, but reached the point of having a Federal Rodenticide Act available for study and possible revision in 1928. At this time, the mammal control chemicals in use were limited to strychnine -- alkaloid and sulphate -arsenic, barium carbonate, th allium sulphate, phosphorus, s odium and calcium cyanide, carbon disulphide, and red squill. -
Toxicological Profile for Beryllium
BERYLLIUM 19 3. HEALTH EFFECTS 3.1 INTRODUCTION The primary purpose of this chapter is to provide public health officials, physicians, toxicologists, and other interested individuals and groups with an overall perspective on the toxicology of beryllium. It contains descriptions and evaluations of toxicological studies and epidemiological investigations and provides conclusions, where possible, on the relevance of toxicity and toxicokinetic data to public health. A glossary and list of acronyms, abbreviations, and symbols can be found at the end of this profile. 3.2 DISCUSSION OF HEALTH EFFECTS BY ROUTE OF EXPOSURE To help public health professionals and others address the needs of persons living or working near hazardous waste sites, the information in this section is organized first by route of exposure (inhalation, oral, and dermal) and then by health effect (death, systemic, immunological, neurological, reproductive, developmental, genotoxic, and carcinogenic effects). These data are discussed in terms of three exposure periods: acute (14 days or less), intermediate (15–364 days), and chronic (365 days or more). Levels of significant exposure for each route and duration are presented in tables and illustrated in figures. The points in the figures showing no-observed-adverse-effect levels (NOAELs) or lowest-observed-adverse-effect levels (LOAELs) reflect the actual doses (levels of exposure) used in the studies. LOAELS have been classified into "less serious" or "serious" effects. "Serious" effects are those that evoke failure in a biological system and can lead to morbidity or mortality (e.g., acute respiratory distress or death). "Less serious" effects are those that are not expected to cause significant dysfunction or death, or those whose significance to the organism is not entirely clear. -
"Beryllium Oxide Digestion Optimization at the Savannah River Site"
"Beryllium Oxide Digestion Optimization at the Savannah River Site" by Davin Jagnandan November, 2002 ==' ¥---- ; A paper submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Master of Public Health in the School of Public Health Abstract Chronic beryllium disease (CBD) is a debilitating lung disorder affecting an estimated 4.6% of past nuclear weapons and beryllium manufacturing workers. The Chronic Beryllium Disease Prevention Program, as set up by the U.S. Department of Energy (DOE), establishes guidelines for maintaining acceptable exposure levels in all beryllium manufacturing facilities. These exposure levels are based on the measuring of total beryllium which includes beryllium metal, beryllium salts, beryllium alloys and beryllium oxide. The most sensitive detection instruments used in industrial hygiene sampling measure beryllium in a solubilized form . Beryllium oxide, in particular, has been shown to resist solubilization unless it is performed in the presence of strong acid(s). This poses a problem for industrial hygienists because beryllium oxide has been shown to have a high level oftoxicity due to its small size and moderate solubility. The current Ip digestion method (EPA 3050B) for all metals at the Savannah River Site 1 involves the use of nitric and hydrochloric acids. It was hypothesized that 1 this method was inadequate for the complete digestion of beryllium oxide. This study examines this issue by comparing method 3050B with two other acid digestion methods. Once the most effective of the three methods was determined, optimization factors such as settling time, heating/reflux time, and hydrogen peroxide addition were examined. -
Study of Phosphorus Behaviour in Levitated Silicon-Iron Droplets
STUDY OF PHOSPHORUS BEHAVIOUR IN LEVITATED SILICON-IRON DROPLETS by Katherine Le A thesis submitted in conformity with the requirements for the degree of Master of Applied Science Department of Materials Science and Engineering University of Toronto © Copyright by Katherine Le 2016 ii Study of Phosphorus Behaviour in Levitated Si-Fe Droplets Katherine Le Master of Applied Science Department of Materials Science and Engineering University of Toronto 2016 Abstract While the treatment of relatively inexpensive ferrosilicon alloys is a potential refining route in order to generate solar grade silicon, phosphorus is one of the more difficult impurities to remove by conventional processing. In this project, electromagnetic levitation was used to investigate the dephosphorization of ferrosilicon alloy droplets exposed to H2-Ar gas mixtures under various experimental conditions including, refining time, temperature (1450°C-1720°C), H2-Ar gas concentrations and flow rate, iron alloying content, and initial phosphorus concentration. Reaction rates increased with higher refining times, temperatures, and H2 gas concentrations. With unknown parameters associated with the kinetics of gas phase reactions, the approach involved comparison of apparent activation energies derived for the chemical reaction and gas diffusion steps of the dephosphorization process. The phosphorus removal rate is thought to be controlled by the interfacial reaction step; further work is required to confirm this conclusion. iii Acknowledgements I would like to express my gratitude and respect to my supervisor, Prof. Alex McLean for the opportunity to work on this research. I am thankful for his guidance, wisdom and encouragement throughout the course of my studies. He is a truly inspiring person, and a great enabler of new learning opportunities. -
