Salient Features of Mercury Mercury is a heavy and silvery-white metal. Mercury usually available inin liquidliquid state; inin normal condition, itit isis only thethe fewfew metallic element that remains in liquid state at room temperature. Mercury is the poor conductor of heat, but it is a good conductor of the electricity.. The freezing point of mercury is −38.830C and the boiling point is 356.730C. Mercury poisoning caused because of thethe ingestingingesting any formform of mercury.. ItIt isis also caused by inhalation of mercury vapor.. https://www.tutorialspoint.com/chemistry_part2/chemistry_mercury.htm 1/3 1/24/2021 Chemistry - Mercury - Tutorialspoint Mercury dissolves many metals including gold and silver to form amalgams. Occurrence of Mercury Mercury is one of the rarest element in the earth’s crust. The richest mercury ores carry about 2.5 percent mercury (in terms of mass). Mercury isis foundfound either as a native (natural) element) or inin corderoite, cinnabar,, livingstonite,livingstonite, etc.etc. minerals.minerals. Mercury iis foundfound thethe region of young mountain belt; thethe belt thatthat keep forcingforcing thethe denser rocks to the crust of the earth. For example, volcanic region or even hot spring regions. Alloys of Mercury Amalgam is the major alloy of mercury.. Compounds of Mercury Following are the major compounds of Mercury − Mercury (II) chloride - HgCl2 Mercury (II) oxide - HgO Mercury sulfide - HgS Mercury (I) – chloride - Hg2Cl2 Dimethylmer - C2H6Hg Mercury (II) nitrate - Hg(NO3)2 Mercury (II) acetate - C4H6O4Hg Mercury (II) sulfate - HgSO4 Mercury (I) iodide - Hg2II2 Mercury selenide - HgSe Mercury (II) fulminate - Hg(CNO)2 Mercury (II) bromide - HgBr2 Mercury (II) iodide - HgI2 Mercury (I) oxide - Hg2O Mercury (I) fluoride - Hg2F2 Mercuric amidochloride - ClH2HgN Diethylmercury - C4H10Hg https://www.tutorialspoint.com/chemistry_part2/chemistry_mercury.htm 2/3 1/24/2021 Chemistry - Mercury - Tutorialspoint Uses of Mercury Mercury is largely used in chemical industries.

It is cycled in the environment and undergoes transformations of its chemical forms. Although the number of chemical species encountered in environmental and biological samples is not large, the range of matrices and the toxicological significance of mercury, with a consequent need for ultra-trace determination, have resulted in a considerable analytical literature. Sensitive and selective methods for mercury determination, micro methods for the determination of mercury species, the occurrence of mercury species in the various environmental compartments, and analytical considerations, including the availability of certified reference materials, are reviewed.

Annex 1. Management Criteria for Substances of Environmental Concern (Automobile Products)
Annex 1. Management Criteria for Substances of Environmental Concern (Automobile Products) 1. Substances subject to management and management classifications We have adopted GADSL for our Management Criteria for Substances of Environmental Concern (Automobile Products). The management classifications and definitions for "prohibited substances" and "declarable substances" are shown in Table 1. [Precautions for use] The specific chemical substances within GADSL only enumerate some of the chemical substances that fall under their class of chemical substances. It does not regulate every chemical substance that falls under said class of chemical substances. The Japanese translation has been included for reference purposes, but there are some substances which do not have official Japanese names. The latest information on GADSL must be obtained and confirmed from the following website. [GADSL] The Global Automotive Declarable Substance List (GADSL) released by the Global Automotive Stakeholder Group (GASG) http://www.gadsl.org/ Table 1. Stanley's management classifications and definitions The reported substances contained within vehicle materials and parts have been indicated as either "P" or "D" via the following definitions.

MERCURY iii UPDATE STATEMENT A Toxicological Profile for Mercury–Draft for Public Comment was released in September 1997. This edition supersedes any previously released draft or final profile. Toxicological profiles are revised and republished as necessary, but no less than once every three years. For information regarding the update status of previously released profiles, contact ATSDR at: Agency for Toxic Substances and Disease Registry Division of Toxicology/Toxicology Information Branch 1600 Clifton Road NE, E-29 Atlanta, Georgia 30333 . MERCURY vii QUICK REFERENCE FOR HEALTH CARE PROVIDERS Toxicological Profiles are a unique compilation of toxicological information on a given hazardous substance. Each profile reflects a comprehensive and extensive evaluation, summary, and interpretation of available toxicologic and epidemiologic information on a substance. Health care providers treating patients potentially exposed to hazardous substances will find the following information helpful for fast answers to often-asked questions. Primary Chapters/Sections of Interest Chapter 1: Public Health Statement: The Public Health Statement can be a useful tool for educating patients about possible exposure to a hazardous substance. It explains a substance’s relevant toxicologic properties in a nontechnical, question-and-answer format, and it includes a review of the general health effects observed following exposure. Chapter 2: Health Effects: Specific health effects of a given hazardous compound are reported by route of exposure, by type of health effect (death, systemic, immunologic, reproductive), and by length of exposure (acute, intermediate, and chronic).
