In this research work we attempt to improve the purity of polymetallic ores in Mongolia whilst developing practical applications of its refinement processes and this paper presents the results of chemical research of extracting transition metal titanium oxides, ferrous oxide and rare earth oxides from polymetallic ore. Thereby, chemical and mineral analysis of polymetallic ore is carried out basis of responses to the support process at various degrees of water whereas transition metal sulphates solubility differ. As a result of sulphate and resulphurization process we have extracted anatase with 62.5 percent titanium dioxide and brookite mineral with 89.6 percent of titanium dioxide as well as mineral with 83.8 percent of ferrous oxide hematite and rare earth oxides with 57.6 percent of cerium oxide. These oxides are identified under various conditions in the thermal processing. The morphology structure and chemical content compound of the mineral has been verified as a result of the XRF, XRD, SEM-EDX analysis.

II Thesis abstract The convulsant alkaloid strychnine is a selective and highly potent antagonist at postsynaptic receptor for the inhibitory neurotransmitter glycine . These properties have led to the extensive use of strychnine as a ligand to probe the postsynaptic glycine receptor. Despite the recent increased understanding of the molecular structure of this receptor protein there is still much dispute as to the nature of the interaction between glycine and strychnine.

    Arsinothricin, an Arsenic-Containing Non-Proteinogenic Amino Acid Analog of Glutamate, Is a Broad-Spectrum Antibiotic

    ARTICLE https://doi.org/10.1038/s42003-019-0365-y OPEN Arsinothricin, an arsenic-containing non-proteinogenic amino acid analog of glutamate, is a broad-spectrum antibiotic Venkadesh Sarkarai Nadar1,7, Jian Chen1,7, Dharmendra S. Dheeman 1,6,7, Adriana Emilce Galván1,2, 1234567890():,; Kunie Yoshinaga-Sakurai1, Palani Kandavelu3, Banumathi Sankaran4, Masato Kuramata5, Satoru Ishikawa5, Barry P. Rosen1 & Masafumi Yoshinaga1 The emergence and spread of antimicrobial resistance highlights the urgent need for new antibiotics. Organoarsenicals have been used as antimicrobials since Paul Ehrlich’s salvarsan. Recently a soil bacterium was shown to produce the organoarsenical arsinothricin. We demonstrate that arsinothricin, a non-proteinogenic analog of glutamate that inhibits gluta- mine synthetase, is an effective broad-spectrum antibiotic against both Gram-positive and Gram-negative bacteria, suggesting that bacteria have evolved the ability to utilize the per- vasive environmental toxic metalloid arsenic to produce a potent antimicrobial. With every new antibiotic, resistance inevitably arises. The arsN1 gene, widely distributed in bacterial arsenic resistance (ars) operons, selectively confers resistance to arsinothricin by acetylation of the α-amino group. Crystal structures of ArsN1 N-acetyltransferase, with or without arsinothricin, shed light on the mechanism of its substrate selectivity. These findings have the potential for development of a new class of organoarsenical antimicrobials and ArsN1 inhibitors. 1 Department of Cellular Biology and Pharmacology, Florida International University, Herbert Wertheim College of Medicine, Miami, FL 33199, USA. 2 Planta Piloto de Procesos Industriales Microbiológicos (PROIMI-CONICET), Tucumán T4001MVB, Argentina. 3 SER-CAT and Department of Biochemistry and Molecular Biology, University of Georgia, Athens, GA 30602, USA.

It also is found in many sewer gases. It is a by-product of many industrial processes. Trace amounts of dis- solved H2S are found in wastewaters in equilibrium with dissolved sulfides and hydrosulfides. It also is found in volcanic eruptions, hot springs and in troposphere. The average concentration of H2S in the air is about 0.05 ppb. The most important applications of hydrogen sulfide involve the production of sodium sulfide and other inorganic sulfides. Hydrogen sulfide obtained as a by-product often is converted into sulfuric acid. It also is used in organic syn- thesis to make thiols or mercaptans. Other applications are in metallurgy for extracting nickel, copper, and cobalt as sulfides from their minerals; and in classical qualitative analytical methods for precipitation of many metals (see Reactions). It also is used in producing heavy water for nuclear reactors. Physical Properties Colorless gas; characteristic odor of rotten eggs; odor threshold 1ppm; sweetish taste; fumes in air; flammable gas, burns with a pale blue flame; refractive index at 589.3nm, 1.000644 at 0°C and 1 atm; density 1.539 g/L at 0°C; critical temperature 100.4°C; critical pressure 88.9 atm; liquefies at –60.7°C; solidifies at –85.5°C; velocity of sound 289 m/sec in H2S gas; slightly soluble in water (0.4% at 20°C); pH of a saturated aqueous solution 4.5; slight- ly acidic; diffusivity in water at 16°C, 1.77x105 cm2/sec; soluble in carbon disulfide, methanol, acetone; very soluble in N-methylpyrrolidinone and alka- nolamines (salt formation occurs: salt dissociates on heating); liquid H2S dis- solves sulfur and SO2.

    . 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.

    Multi-Residue Determination of Organic Arsenical Drugs in Feeds by LC-MS/MS

    Multi-Residue Determination of Organic Arsenical Drugs in Feeds by LC-MS/MS Geneviève Grenier, Melanie Titley & Lise-Anne Prescott AAFCO Laboratory Methods and Services Committee meeting 2016-01-18 Background • Animal Feed Division of CFIA identified a high priority need for the determination of three organic arsenicals (arsanilic acid, roxarsone and nitarsone) at residue levels in animal feed • These are withdrawal drugs and are priority food contaminants • Current test methods are at guarantee levels greater than 10% minimum use rate • Therefore, current methods not well suited for residue or traceback testing • Requested feed residue LOQ of 1 mg/kg for all three organic arsenicals 2 Background • UHPLC-PDA Challenges • Extract were very dirty • Tried sample clean-up using Oasis MAX SPE • Still very dirty • HPLC Challenges • Compounds elute too easily • Analytical column must : retain and separate compounds, and give good peak shape • Analytical column : Phenomenex Onyx Monolithic C18 100 X 3.0mm 3 Background • LC/MS/MS method (positive mode) • Column: Phenomenex Onyx Monolithic C18 100 X 3.0mm • Linearity problems with Internal Standard (IS) • Internal standard – 4-hydroxyphenylarsonic acid • Peak area of the internal standard increased with increasing analyte concentration • Cause • 4-hydroxyphenyl arsanic acid co-elute with Arsanilic acid and have similar m/z 4 New method - summary • Liquid chromatography combined with atomic and molecular mass spectrometry for speciation of arsenic in chicken liver.
