Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life.Some metals are toxic when they form poisonous soluble compounds. . Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain for
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel. [4] It is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. [5] The mineralogical form of NiO, bunsenite, is very rare.
The major source of nickel exposure is oral consumption, as nickel is essential to plants. [126] Typical background concentrations of nickel do not exceed 20 ng/m 3 in air, 100 mg/kg in soil, 10 mg/kg in vegetation, 10 μg/L in freshwater and 1 μg/L in seawater. [127] Environmental concentrations may be increased by human pollution.
Nickel is both naturally abundant – it is the fifth most common element on earth – and widely used in industry and commercial goods. [2] Workplace nickel exposure is common in many industries, and the performance of normal work tasks can result in nickel skin levels sufficient to elicit dermatitis. [2]
Nickel oxide may refer to: Nickel(II) oxide, NiO, green, well-characterised oxide; Nickel(III) oxide, Ni 2 O 3, black, not well-characterised oxide; Nickel(IV) oxide;
Nickel (III) oxide is the inorganic compound with the formula Ni 2 O 3. It is not well characterized, [1] and is sometimes referred to as black nickel oxide. Traces of Ni 2 O 3 on nickel surfaces have been mentioned. [2] [3] Nickel (III) oxide has been studied theoretically since the early 1930s, [4] supporting
