4.3.3.6 Zinc

Оглавление

Zinc (Zn) is a 3D block element which is found in the Earth's crust. Generally, Zn is found in +2 oxidation states and it forms compounds with the anions, amino acid, and organic acid. Zn is soluble in water bodies at neutral and acidic pH values. At basic pH, it makes the carbonate and hydroxide compounds, which are insoluble in water. The anthropogenic and natural sources release the Zn contamination in ground as well as surface water. Zn is an essential element for the human body in limited quantities. The exposure to high concentrations of Zn is harmful for many age groups (Hashim et al. 2011).
