  • Nanomaterial Safety
    Nanomaterial Safety What are Nanomaterials? Nanomaterials or nanoparticles are human engineered particles with at least one dimension in the range of one to one hundred nanometers. They can be composed of many different base materials (carbon, silicon, and various metals). Research involving nanomaterials ranges from nano-particle synthesis to antineoplastic drug implants to cell culture work. Material Scientists, Chemists, Biologists, Biochemists, Physicists, Microbiologists, Medical-related disciplines and many engineering disciplines (Mechanical, Chemical, Biological and Environmental, etc.) perform research using nanomaterials. Naturally created particles of this size range are normally called ultra-fine particles. Examples are welding fumes, volcanic ash, motor vehicle exhaust, and combustion products. Nanomaterials come in many different shapes and dimensions, such as: • 0-dimensional: quantum dots • 1-dimensional: nanowires, nanotubes, • 2-dimensional: nanoplates, nanoclays • 3-dimensional: Buckyballs, Fullerenes, nanoropes, crystalline structures Nanoparticles exhibit very different properties than their respective bulk materials, including greater strength, conductivity, fluorescence and surface reactivity. Health Effects Results from studies on rodents and in cell cultures exposed to ultrafine and nanoparticles have shown that these particles are more toxic than larger ones on a mass-for-mass basis. Animal studies indicate that nanoparticles cause more pulmonary inflammation, tissue damage, and lung tumors than larger particles Solubility, shape, surface area and surface chemistry are all determinants of nanoparticle toxicity There is uncertainty as to the levels above which these particles become toxic and whether the concentrations found in the workplace are hazardous Respiratory Hazards: • Nanoparticles are deposited in the lungs to a greater extent than larger particles • Based on animal studies, nanoparticles may enter the bloodstream from the lungs and translocate to other organs and they are able to cross the blood brain barrier.

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 Use of Animals.

  • Spectrophotometric Determination of Thiocyanate In
    Investigative Forensic Sciences © All rights are reserved by Buddha D. Paul and Thomas Research Article Open Access Spectrophotometric Determination of Thiocyanate in Human Saliva by a Unique Iodine-Azide-Chromogenic Substrate Reaction and its Application in Distinguishing Tobacco Smokers from Non-Smokers† Buddha D. Paul and Thomas Bosy Division of Forensic Toxicology, Office of the Armed Forces Medical Examiner, Dover AFB, Delaware, USA. Abstract A method to detect thiocyanate (SCN) in human saliva is presented. Thiocyanate concentrations appear to be diagnostic when classifying smokers or non-smokers, and in determining some clinical conditions. The method involves the reaction of SCN with excess iodine and azide, and spectroscopic detection of unreacted iodine by a chromogenic substrate, ABTS. The calibration was linear over the range of 12.5-150 µmol/L (slope = 0.0086 delta-Abs/SCN µmol/L, intercept = -0.0160 delta-Abs, R2 0.9998). The method was applied to analyze 29 saliva specimens. The results were similar to those obtained from a gas chromatography-mass 2 spectrometry method (slope = 0.9595, R 0.9790). Based on Grubbs equation applied to specimens from non-smoking subjects, a threshold concentration of 1100 µmol/L for SCN was determined to distinguish smokers from the non-smokers. The SCN concentrations in 18 out of 20 saliva specimens collected from 2 smokers were above this threshold. The specimens from smokers were also examined for nicotine and cotinine by a GCMS method. While nicotine concentrations were found to vary, the cotinine concentrations remained stable, 134+29 ng/mL. Generally, the presence of nicotine/cotinine in specimens only indicates exposure to tobacco products, but the presence of any of these compounds with elevated SCN, is an indication of smoking.

  • The Atmospheric Chemical Vapour Deposition of Coatings on Glass
    The Atmospheric Chemical Vapour Deposition Of Coatings On Glass. by Kevin David Sanderson, B.Sc. A thesis submitted to Imperial College of Science Technology and Medicine for the degree of Doctor of Philosophy January, 1996 The copyright of this thesis rests with the author and no quotation from it or information derived from it may be published without the prior written consent of the author. Some of the material presented in this thesis is of a confidential nature. It is therefore requested that anyone reading this thesis maintains this confidentiality until the thesis becomes publicly available. Abstract: The deposition of thin films of indium oxide, tin doped indium oxide (ITO) and titanium nitride for solar control applications have been investigated by Atmospheric Chemical Vapour Deposition (APCVD). Experimental details of the deposition system and the techniques used to characterise the films are presented. Results from investigations into the deposition parameters, the film microstructure and film material properties are discussed. A range of precursors were investigated for the deposition of indium oxide. The effect of pre-mixing the vaporised precursor with an oxidant source and the deposition temperature has been studied. Polycrystalline In203 films with a resistivity of 1.1 - 3 x 10-3 ) cm were obtained with In(thd)3 , oxygen and nitrogen. The growth of ITO films from In(thd)3, oxygen and a range of tin dopants is also presented. The effect of the dopant precursor, the doping concentration, deposition temperature and the effect of additives on film growth and microstructure is discussed. Control over the preferred orientation growth of ITO has been achieved by the addition of acetate species during film growth.

  • Used at Rocky Flats
    . TASK 1 REPORT (Rl) IDENTIFICATION OF CHEMICALS AND RADIONUCLIDES USED AT ROCKY FLATS I PROJECT BACKGROUND ChemRisk is conducting a Rocky Flats Toxicologic Review and Dose Reconstruction study for The Colorado Department of Health. The two year study will be completed by the fall of 1992. The ChemRisk study is composed of twelve tasks that represent the first phase of an independent investigation of off-site health risks associated with the operation of the Rocky Flats nuclear weapons plant northwest of Denver. The first eight tasks address the collection of historic information on operations and releases and a detailed dose reconstruction analysis. Tasks 9 through 12 address the compilation of information and communication of the results of the study. Task 1 will involve the creation of an inventory of chemicals and radionuclides that have been present at Rocky Flats. Using this inventory, chemicals and radionuclides of concern will be selected under Task 2, based on such factors as the relative toxicity of the materials, quantities used, how the materials might have been released into the environment, and the likelihood for transport of the materials off-site. An historical activities profile of the plant will be constructed under Task 3. Tasks 4, 5, and 6 will address the identification of where in the facility activities took place, how much of the materials of concern were released to the environment, and where these materials went after the releases. Task 7 addresses historic land-use in the vicinity of the plant and the location of off-site populations potentially affected by releases from Rocky Flats.
