Zinc has been popularly used as zinc gluconate or zinc acetate lozenges for treating the common cold, [12] and therefore the safety of usage at about 100 mg/day level is a relevant question. Unlike iron, the elimination of zinc is concentration-dependent. [13]
Zinc is also used in contemporary pipe organs as a substitute for the traditional lead/tin alloy in pipes. [134] Alloys of 85–88% zinc, 4–10% copper, and 2–8% aluminium find limited use in certain types of machine bearings. Zinc has been the primary metal in American one cent coins (pennies) since 1982.

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 ...
Diethylzinc (C 2 H 5) 2 Zn, or DEZ, is a highly pyrophoric and reactive organozinc compound consisting of a zinc center bound to two ethyl groups. This colourless liquid is an important reagent in organic chemistry. It is available commercially as a solution in hexanes, heptane, or toluene, or as a pure liquid.
RDA for pregnancy is 11 mg/day. RDA for lactation is 12 mg/day. For infants up to 12 months, the RDA is 3 mg/day. For children ages 1–13 years, the RDA increases with age from 3 to 8 mg/day. As for safety, the IOM sets Tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of zinc the adult UL ...
Pyrometallurgy processing reduces zinc oxide with carbon or carbon monoxide at 950 °C (1,740 °F) into the metal, which is distilled as zinc vapor. [81] The zinc vapor is collected in a condenser. [80] Electrowinning processing leaches zinc from the ore concentrate by sulfuric acid. [82] After this step electrolysis is used to produce zinc ...
The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. [9]
Zinc production and proven reserves exist at a higher scale than lithium metal due to zinc’s use in galvanization and its broad geographic availability. [12] Other benefits of zinc metal as an anode material include its compatibility with both aqueous and non-aqueous electrolytes and its higher safety and lower environmental toxicity compared ...
