This Public Health Statement is the summary chapter from the Toxicological Profile for Aluminum. It is one in a series of Public Health Statements about hazardous substances and their health effects. A shorter version, the ToxFAQsâ¢, is also available.This information is important because this substance may harm you.ood. You cannot avoid exposure to aluminum because it is so common and widespread in the environment. Exposure to the levels of aluminum that are naturally present in food and water and the forms of aluminum that are present in dirt and aluminum pots and pans are not considered to be harmful.
Aluminum being the most abundant metal in the earthâs crust (at 8.2% of the total metals) is never found free in nature. Aluminum is reactive and will react spontaneously with water and/or air to form aluminum oxide.Aluminum oxide, Al2O3, forms a stable passive layer that protects aluminum from corrosion or further oxidation.This layer is about 4 nm thick and will provide corrosion protection as long as this oxide layer is stable. Aluminum is an amphoteric metal and can react with an acid as well as a base.The protective layer of aluminum oxide will deteriorate in environments with high or low pH or even in environments where aggressive ions are present.luminum is reactive and will react spontaneously with water and/or air to form aluminum oxide. Aluminum oxide, Al2O3, forms a stable passive layer that protects aluminum from corrosion or further oxidation.
