| 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 . |
| carcinogen classification | default_key: No indication of carcinogenicity to humans . |
