Toxicity
Zinc is an essential element in the growth of human beings and animals, and is not normally considered
toxic. However zinc in excess can affect the blood, brain, eyes, kidney, pancreas, and throat. Symptons of
zinc toxicity include nausea, vomiting and fever. Recent research indicates zinc toxicity could contribute to
neuronal loss in the brain.
Very toxic for water organisms.
Applications
Plating of screws and other metal components.
The metal is employed to form numerous alloys with other metals. Steel, brass, nickel silver, commercial
bronze, spring bronze, German silver, soft solder, and aluminum solder are some of the more important
alloys. Large quantities of zinc are used to produce die castings, used extensively by the automotive, electrical,
and hardware industries.
It is widely used in the manufacture of paints, rubber products, cosmetics, pharmaceuticals, floor coverings,
plastics, printing inks, soap, storage batteries, textiles, electrical equipment, and other products.
