Found in nature as silica (e.g. in quartz and sand) it is not known whether silicon is an essential element in the human body, but it is found mainly in the skin, tendons, bones and artery walls. In body fluids, silicon is found mainly in the form of silicic acid. Work with animals has shown that silicon is needed for connective tissue metabolism and bone development. In the diet, silicon is found mainly in association with fibre, particularly in the husks of grains. Oats, barley, millet and soy beans are especially rich sources of silicon.
Silicon may also be present in drinking water. Consumption of 2 litres/day of water could result in consuming up to 10 mg silicon per day.
Exposure to high levels of airborne silica occurs in occupations such as quarry workers, miners, foundry workers and sand blasters. Silica deposited in the lungs can be slowly absorbed.
