Animal toxicity Nickel carbonyl [nickel tetracarbonyl, Ni(CO)4] is a colorless liquid-metal compound (boiling point, 43) and was discovered by Mond and co- workers in 1890. Agency for Toxic Substances and Disease Registry Division of Toxicology ToxFAQs TM August 2005 This fact sheet answers the most frequently asked health questions (FAQs) about nickel. Elevated incidences of lung and The core of the earth contains 8.5% nickel, deep-sea nodules 1.5%; meteorites have been found to contain 5–50% nickel (5). Acute animal tests in rats have shown nickel compounds to exhibit acute toxicity values ranging from low to high. Our knowledge on the molecular mechanisms of nickel toxicity and carcinogenicity is sketchy. The toxicity of nickel compounds appears to be related to the solubility of the compound. Some fatal cases were noted following exposure to nickel carbonyl, and by the early 1930s, nickel was a recognized cause of contact dermatitis. It is highly volatilized and readily dissociates in air. (6) Chronic Effects (Noncancer): Page 5 of 10 Component Exposure Limits . NICKEL CARBONYL 13463-39-3 ACGIH: 0.05 ppm Ceiling as Ni NIOSH: 0.001 ppm TWA ; 0.007 mg/m3 TWA 2 ppm IDLH General toxicity The main target organ for nickel induced toxicity in animals is the respiratory tract [3]. Nebeker et dl. The findings suggest that nickel be identified as a toxic air contaminant which may disproportionately impact children, pursuant to Health and Safety Code, Section 39669.5(c). With both species, hardness was the only significantly correlated parameter. The toxic effects of nickel on the lung were recog-nized first by Agricola in the 16th century. These mechanisms are likely to involve binding of nickel cation to tissue and cellular components, detrimental to their structure and function, and disruption of the homeostasis of essential metals. The toxic effects of nickel result from its ability to replace other metal ions in enzymes, proteins or bind to cellular compounds (Cempel and Nikel, 2005), and among animals, micro-organisms and plants, nickel is reported by Nielsen (1980a) to interact with at least … Nickel is widely distributed in nature, forming about 0.008% of the earth’s crust. The natural background levels of nickel in water are relatively low, in open ocean water 0.228– Nickel is one of the most potent human allergens. This fact sheet is one in a series Inhalation N ickel contam ination of intravenous fluids warrants concern, owing to three specific toxic effects o f Ni2+: (a) cardiac toxic ity , especially increased coronary artery resistance, (b ) oxytocic action on th e u terus, and (c) allergic reactions, since nickel is a common allergen. The key values are summarized below. overall toxicity profile of nickel and its compounds, but do not contribute to the derivation of the RELs are described in Appendix A. Nickel and Inorganic Nickel Compounds Page i DSD History Effective Date Reason June 1, 2011 Original DSD posted as final July 26, 2017 DSD text revised to allow the values derived in this DSD to be used conservatively for some organic nickel compounds, if applicable. Nickel as NiCl 2 was applied to the soil in solution form @ 0mgL-1(Control), 25mg L-1, 50mg L-1, 100mg L-1 and 150mg L-1. (1985) reported that rainbow trout were more sensitive when 12-months old than when 3-months Several acute animal studies have reported soluble nickel sulphate as being the most toxic and insoluble nickel oxide the least toxic [2].

(Chickpea) varieties were observed. hardness and TOC on the acute toxicity of nickel to both Daphnia pulicaria and the fathead minnow (Table 6).
