Aluminium is the most abundant metal in the Earth’s crust. As a soft and very light metal, it is easily malleable and is used, amongst other things, in lightweight construction and packaging.Aluminium oxide is hard and temperature- stable. It is often used for abrasives, bone substitutes, melting pots and watch glasses and a variety of other applications. Aluminium oxide is a proven remedy for heartburn: it helps to balance stomach acid.<\/p>\n

Aluminium occurs naturally in small quantities in many foods. In addition, it can leach into food from packaging, tins, cling film or cookware – particularly in acidic or salty foods such as tomato sauce, fruit, sauerkraut or marinades. Aluminium is also found in some antiperspirants and medicines, such as antacids.<\/p>\n

Aluminium dust can be generated during grinding, welding, milling or aluminium production and may be inhaled.<\/p>\n

When used as an abrasive (e.g. in sandpaper, where it is usually referred to as corundum), aluminium oxide can produce dust that may be inhaled. It is therefore advisable to wear a respirator and\/or use an extraction system.<\/p>\n

<\/h5>\n
Is there any risk from this material to humans and the environment?<\/h5>\n

Aluminium is not normally absorbed through intact skin upon contact with objects, packaging or jewellery. The tolerable weekly intake (TWI) has been set at 1 mg\/kg body weight.<\/p>\n

Aluminium oxides are among the less hazardous substances. They are only toxic<\/span> in large quantities.<\/p>\n

 <\/p>\n

Conclusion<\/h5>\n

Aluminium has no natural function in the human body. In everyday life, the human body comes into contact with only small amounts of aluminium oxide (nano)particles; consequently, there is no risk to health.<\/p>\n
