thiocyanic acid
A hydracid that is cyanic acid in which the oxygen is replaced by a sulfur atom.
Acetate
A monocarboxylic acid anion resulting from the removal of a proton from the carboxy group of acetic acid. Acetate, also known as acetic acid or ethanoate, is a member of the class of compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Acetate is soluble (in water) and a weakly acidic compound (based on its pKa). Acetate can be found in a number of food items such as pitanga, soursop, green bean, and beech nut, which makes acetate a potential biomarker for the consumption of these food products. Acetate is a non-carcinogenic (not listed by IARC) potentially toxic compound. An acetate is a salt formed by the combination of acetic acid with an alkaline, earthy, or metallic base. "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C2H3O2−. The neutral molecules formed by the combination of the acetate ion and a positive ion (called a cation) are also commonly called "acetates" (hence, acetate of lead, acetate of aluminum, etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion CH3CO2−, or CH3COO− . In cases of skin or eye exposure, the area should be flushed with water and burns covered with dry, sterile dressings after decontamination. If ingested, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution. Watch for signs of respiratory insufficiency and assist respiration if necessary (A569) (T3DB).
Cobalt
Cobalt has a molecular weight of 58.9 and an atomic number of 27. In the Periodic Table, close to other transition metals, it is situated in group 8, together with rhodium and iridium and it can occur in four oxidation states (0, +2, +3 and +4). The +2 and the ground state are the most common. Cobalt occurs in the minerals cobaltite (Co, Fe) AsS, smaltite (CoAs2), and erythrite Co3(AsO4)2.8H2O, and is often associated with nickel, silver, lead, copper, and iron ores, from which it is most frequently obtained as a by-product. Depending on the considered species, cobalt has multiple industrial applications including the production of alloys and hard metal, diamond polishing, drying agents, pigments and catalysts. Hard metal or cemented carbide is a powder metallurgical product consisting of hard, wear-resistant carbide particles bound together (cemented) with a ductile metal binder (i.e. metallic Co) by liquid phase sintering. Tungsten carbide (WC) is produced by mixing tungsten powder with pure carbon powder at high temperature; hereafter WC is mixed with Co powder to which paraffin is added as a binder. Depending on specific requirements related to their use, hard metals might additionally contain small quantities of chromium, niobium, molybdenum, titanium, tantalum or vanadium carbides. Inhalation and skin contact are the main occupational exposure routes. Occupational exposure to cobalt may result in adverse health effects in different organs or tissues, including the respiratory tract, the skin, the hemapoietic tissues, the myocardium or the thyroid gland. In addition, teratogenic and carcinogenic effects have been observed in experimental systems and/or in humans. For the general population, the diet constitutes the main route of exposure to cobalt, since it is an essential component of Vitamin B12 (hydroxycolalamin). Cobalt functions as a co-factor in enzyme catalysed reactions and is involved in the production of erythropoietin, a hormone that stimulates the formation of erythrocytes. This last property of cobalt was applied in the past as a therapy for anaemia. The carcinogenic potential of cobalt and its compounds was evaluated in 1991 by the International Agency for Research on Cancer (IARC), which concluded that there was inadequate evidence for carcinogenicity in humans (lung cancer) but sufficient evidence in experimental animal studies. In most experimental studies considered, the routes of exposure were, however, of questionable relevance for cancer risk assessment in humans for example, local sarcomas after intra-muscular injection. The general conclusion was that cobalt and its compounds are possibly carcinogenic to humans (group 2B). Since this evaluation, additional data have been accumulated which generally indicate that, depending on the considered cobalt species, different outcomes regarding toxicity, mutagenicity and carcinogenicity can be observed. Physiologically, it exists as an ion in the body. Co(II) ions are genotoxic in vitro and in vivo, and carcinogenic in rodents. Co metal is genotoxic in vitro. Hard metal dust, of which occupational exposure is linked to an increased lung cancer risk, is proven to be genotoxic in vitro and in vivo. Possibly, production of active oxygen species and/or DNA repair inhibition are mechanisms involved. Given the recently provided proof for in vitro and in vivo genotoxic potential of hard metal dust, the mechanistic evidence of elevated production of active oxygen species and the epidemiological data on increased cancer risk, it may be advisable to consider the possibility of a new evaluation by IARC.(PMID: 14643417).
