Zinc

GENERAL INFORMATION
Zinc is an essential trace metal with very low toxicity in humans. Zinc can occur naturally in drinking water. Zinc contamination can result from corrosion of galvanized pipes by soft, acidic water. Zinc is used in fertilizers and may be found in landfill leachate or in industrial wastes.

HEALTH EFFECTS
Harmful effects generally begin at levels 10-15 times higher than the amount needed for good health. Large doses taken by mouth even for a short time can cause stomach cramps, nausea, and vomiting. Taken longer, it can cause anemia and decrease the levels of your good cholesterol.
