Silicon is the most abundant and stable element in the lithosphere.
It is necessary for normal growth and bone development. The highest
levels are found in connective tissues such as the aorta, trachea,
tendons, bones, and skin. The silicon concentration in these tissues
declines with age, and the level in the arterial wall has been
shown to decrease with the development of atherosclerosis. Silicon
toxicity is almost invariably associated with silicosis due to
continued inhalation of silica particles in mining. It is monitored
in occupational exposure to asbestos and for silicone implant
leakage. Elevated levels are found in renal dialysis patients.
