Aluminium
Food is the main source of aluminum. Drinking water has more aluminum than solid foods. aluminum in food may be absorbed more than aluminum from water. Major sources of human exposure by mouth to aluminum include food (because of its use in food additives, food and beverage packaging, and cooking utensils), drinking water (because of its use in water treatment), and medicines that have aluminum in it. Very high exposure of aluminum are mostly limited to miners, aluminum production workers, and dialysis patients.
