Zinc is one of the most common elements in the earth's crust. It is found in air, soil, and water, and is present in all foods. Pure zinc is a bluish-white shiny metal. Zinc has many commercial uses as coatings to prevent rust, in dry cell batteries, and mixed with other metals to make alloys like brass, and bronze. A zinc and copper alloy is used to make pennies in the United States. Zinc combines with other elements to form zinc compounds. Common zinc compounds found at hazardous waste sites include zinc chloride, zinc oxide, zinc sulfate, and zinc sulfide. Zinc compounds are widely used in industry to make paint, rubber, dyes, wood preservatives, and ointments.

A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with anemia, short stature, hypogonadism, impaired wound healing, and geophagia. It is identified by the symbol Zn. A newer study suggests implies that an imbalance of zinc is associated with the neuronal damage associated with traumatic brain injury, stroke, and seizures. Understanding the mechanisms that control brain zinc homeostasis is, therefore, imperative to the development of preventive and treatment regimens for these and other neurological disorders. In addition to the above, recent review articles have already demonstrated the important role of zinc in the pathophysiology and treatment of affective disorders, plus discussed the potential value of zinc as a marker of these diseases. Most recently, research has shown that polymorphism of the common polymorphism in zinc transporter SLC30A8/ZnT8 may increase susceptibility to type 2 diabetes provided novel insights into the role of zinc in diabetes.
Zinc is a metabolite found in or produced by Escherichia coli .
Zinc is an essential mineral and heavy metal that is included in most over-the-counter multivitamin and mineral supplements, and is used therapeutically in higher doses because of its ability to block copper absorption as maintenance therapy of Wilson disease. Zinc has not been associated with worsening of serum enzyme elevations during therapy or with clinically apparent liver injury.
Zinc is a natural product found in Artemia salina, Leonurus sibiricus, and other organisms with data available.

hazards summary
Zinc is one of the most common elements in the earth's crust. It is found in air, soil, and water, and is present in all foods. Pure zinc is a bluish-white shiny metal. Zinc has many commercial uses as coatings to prevent rust, in dry cell batteries, and mixed with other metals to make alloys like brass, and bronze. A zinc and copper alloy is used to make pennies in the United States. Zinc combines with other elements to form zinc compounds. Common zinc compounds found at hazardous waste sites include zinc chloride, zinc oxide, zinc sulfate, and zinc sulfide. Zinc compounds are widely used in industry to make paint, rubber, dyes, wood preservatives, and ointments.Zinc is essential to plant and animal life. It is in more than 300 enzymes involved in all aspects of metabolism. Zn is also needed for the proper structural function of proteins. Zn deficiency causes failed growth and development. Zn is necessary for healthy immunity and wound healing. Zn is depleted in some soils. Plant ligands, e.g., phytate and lignin, can interfere with Zn absorption. 20% of the world's people are at risk for Zn deficiency. Zn supplements are the most common source of excess Zn. Excess intake may precipitate copper deficiency. Excess Zn in drinks, up to 2500 mg/L, caused vomiting, diarrhea, and abdominal pain. Zinc oxide fume causes metal fume fever, and zinc chloride fume causes acute pneumonitis. Produces flammable hydrogen when in contact with moisture. Zinc powder or dust are usually coated with zinc carbonate to reduce the risk of spontaneous combustion. Zinc dust is not known to be harmful after inhalation or contact with the skin or eyes. Zinc is a hepatotoxic agent. See Zinc chloride fume. See Zinc oxide.
toxicity summary
Excessive zinc intake alters copper and iron absorption, most likely through competitive binding in intestinal mucosal cells. Stomach acid dissolves metallic zinc, producing zinc chloride, which is a corrosive product damaging the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc.
symptoms
Ingestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation.
health effects
Chronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of HDL cholesterol in the body. It is also believed to cause pancreatic and reproductive damages. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase have been linked to amyotrophic lateral sclerosis .
