The chemical element aluminum occurs almost exclusively in compounds in nature, whereby it is one of the most common elements of the earth's crust. Aluminum is used as a material in the manufacture of a wide variety of products, such as aluminum foil, grill trays or car rims. Small amounts of aluminum are also ingested through food, with the majority of the ingested element being excreted in healthy people. If kidney function is impaired, however, it can accumulate in the body, so that toxic concentrations can be reached, which can lead to, among other things, death of the brain cells and impairment of cognitive abilities. Aluminum salts can also be absorbed through the skin and pose a health risk that should not be underestimated with regular contact (e.g. through some deodorants).
