Aluminum Toxicity Winchester Hospital

Aluminum toxicity occurs when a person ingests or breathes high levels of aluminum into the body. Aluminum is the most plentiful metal in the earth s crust. It is present in the environment combined with other elements such as oxygen silicon and fluorine. Exposure to aluminum is usually not harmful but exposure to high levels can cause serious health problems.
