Zinc toxicity is a medical condition involving an overdose on, or toxic overexposure to, zinc. Such toxicity levels have been seen to occur at ingestion of greater than 50 mg of zinc. [1] [unreliable medical source?] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria ...
When two metals touch each other and water is present, electrolysis occurs. [2] One well known example is the reaction between zinc (Zn) and iron (Fe). Zinc atoms will lose electrons in preference to the iron as they are more electropositive and therefore zinc is oxidized and corrodes. Zn(s)→ Zn 2+ (aq) +2e (oxidation)

[2] [3] There is often cross-sensitization, where a person allergic to one metal may become allergic to another, but monosensitization, reacting to just one metal, is also possible. [4] For instance, many people allergic to nickel are often also allergic to cobalt (a similar element often found in the same places as nickel) and palladium.
Zinc is more reactive than iron or steel and thus will attract almost all local oxidation until it completely corrodes away. [125] A protective surface layer of oxide and carbonate (Zn 5 (OH) 6 (CO 3) 2) forms as the zinc corrodes. [126] This protection lasts even after the zinc layer is scratched but degrades through time as the zinc corrodes ...
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.
Zinc, problematic for high vacuum and higher temperatures, present in some construction alloys, e.g. brass and some brazing alloys. Tends to poison hot cathodes and form conductive deposits on surfaces. [3] Any materials that have been zinc-coated by galvanization should be avoided, or they have the coating removed first.

Roughly one quarter of all zinc output in the United States (2009) is consumed in the form of zinc compounds, a variety of which are used industrially. [ 92 ] Cadmium has many common industrial uses as it is a key component in battery production, is present in cadmium pigments , [ 102 ] coatings, [ 90 ] and is commonly used in electroplating ...
