what is aluminium toxic amount on a human's general physiological system? and what is the usual amount aluminium injested?thankyou
It is estimated that the normal person takes in between 3 and 10 milligrams of aluminum per day. Aluminum is the most abundant metallic element produced by the earth. It can be absorbed into the body through the digestive tract, the lungs and the skin, and is also absorbed by and accumulates in the bodies tissues. Aluminum is found naturally in our air, water and soil. It is also used in the process of making cooking pots and pans, utensils and foil. Other items such as over the counter pain killers, anti-inflammatory products, and douche preparations can also contain aluminum. Aluminum is also an additive in most baking powders, is used in food processing, and is present in antiperspirants, toothpaste, dental amalgams, bleached flour, grated cheese, table salt, and beer, (especially when the beer is in aluminum cans). The biggest source of aluminum, however, comes from our municipal water supplies. Aluminum is excreted by the kidneys, therefore toxic amounts can impair kidney function. Aluminum can also accumulate in the brain causing seizures and reduced mental alertness. The brain is normally protected by a blood-brain barrier, which filters the blood before it reaches it. Elemental aluminum does not pass easily through this barrier, but certain compounds contained within aluminum, such as aluminum fluoride do. Interestingly, many municipal water supplies are treated with both aluminum sulfate and aluminum fluoride. These two chemicals can also combine easily in the blood. Aluminum fluoride is also poorly excreted in the urine.
