Aluminium (Al) is the most widely distributed metal in the environment and is extensively used in daily life that provides easy exposure to human beings. The exposure to this toxic metal occurs through air, food and water[23,25]. However, there is no known physiological role for aluminium within the body—no known diseases are linked to aluminum shortages—and hence this metal may produce adverse physiological effects[7,25,31].
Aluminum causes problems in the body largely by competing with several other elements with similar characteristics. If you are deficient in such minerals as magnesium, calcium, or iron, then aluminum is always there to take their place inside your cells. Although the body tries to excrete most of the aluminum it takes in, any excess is deposited in various tissues including bone, brain, liver, heart, spleen, and muscle. In certain tissues with relatively low turnover—such as the brain—aluminum is difficult to remove once it's in place, resulting in long-term damage.
In different researches, scientists have identified Aluminum's toxicity to human body in various ways:
- Al is associated with Alzheimer’s Disease (AD)[2,3-6,12-16]
- Apoptotic pathway is believed to represent an important mechanism for the physiological or pathological neural cell death.
- It has been reported that aluminum (Al) can induce apoptosis in neural cells of rodent models and is associated with Alzheimer’s Disease (AD).
- Those neurofibrillary tangles associated with Alzheimer's disease contain aluminum.
- The available data suggest that Al can induce DNA damage by modifying the structure of chromatin through the induction of reactive oxygen species or by damaging lysosomal membranes and liberating DNase.
- The study points toward oxidative stress or liberation of DNase as the major source of DNA damage induced by Al.
- The estrogen-like effects of Al salts have led to their classification as a metalloestrogen
- Aluminium increases estrogen-related gene expression in human breast cancer cells cultured in the laboratory[9,19]
- Some researchers have expressed concerns that the aluminium in antiperspirants may increase the risk of breast cancer[8,22]
