Aluminum, the abundant mineral found in the earth’s crust, plays a significant role in both animal and plant tissues. It is also commonly present in natural water sources. Being a highly reactive trivalent cation, aluminum readily forms compounds with various elements. In its natural state, aluminum is typically combined with oxygen, silicon, and fluorine. However, when excessive levels of aluminum accumulate in the body, it can lead to a condition known as aluminum toxicity or aluminum poisoning.
Aluminum Exposure: Inevitable and Widespread
When it comes to aluminum exposure, it is nearly impossible to completely avoid. This mineral can be found in various sources, making it a common element in our daily lives. For instance, tap water often contains aluminum due to the use of aluminum sulfate in water purification facilities. Additionally, suspended particles of dust in the air also contain traces of aluminum.
The levels of airborne aluminum can vary depending on factors such as weather conditions, location, and the presence of urban or industrial activities. While most individuals inhale minimal amounts of aluminum, studies have detected small traces of this mineral in lung tissue and nearby lymph nodes.
Aluminum in Consumable Sources
Aluminum can be found in various orally ingested sources. Manufacturers often incorporate aluminum into flour, baking powder, and food coloring agents during the processing stage. Additionally, table salt commonly contains aluminum as an anti-caking agent. On average, adults consume approximately seven to nine milligrams of aluminum daily. Other potential sources of aluminum intake include aluminum cans, food containers, and cooking utensils. Certain medications and antacids may also contain high levels of aluminum, with some doses containing up to 600 milligrams. While it is possible to absorb aluminum through the skin via antiperspirants, most medical experts consider this type of exposure to be minimal and insignificant.
