Aluminum is the third most abundant element in earth’s crust, but its chemical properties have prevented its presence in the biological cycle of living organisms. Nevertheless, the acidification of the environment due mainly to human intervention has facilitated its solubilitation, thus increasing its bioavailability. Toxic effects of aluminum in the human body have been reported, and this element has been related with neurodegerentative diseases such as Alzheimer Disease. Aluminum has also been claimed to exert an important pro-oxidant activity.
