Zinc

formula: Zn; CAS Registry Number: 7440-66-6

Rather common element which occurs mainly in ores

Other applications include those in electrical industry (batteries), in building industry, in chemical and in pharmaceutical industries.

It enters soils and waters through weathering of rocks, atmospheric deposition, waste water, sewage sludge, and landfill.

Zinc is essential for all organisms and body concentrations are efficiently regulated by homoeostasis in higher animals to prevent deficiency.
However, it also has toxic properties and can affect the development of organisms.

Several plants and animals are capable to accumulate zinc.
