Knowledge of stable strontium did not advance significantly until extensive studies were undertaken on the effects of radioactive strontium. It is an element naturally occurring in the food chain and is applied in various areas of technology. However, diet and water are the main sources of human exposure to strontium. Consequently, the levels in drinking water and foodstuffs are of great interest from the toxicological and nutritional points of view. Worldwide, the strontium intake of adults varies between 0.1 and 4 mg/day which is normal and without any risk for the population. Occupational exposure to strontium or its compounds is rare and negligible. A review of worldwide alimentary strontium intake is given. In summa, strontium is a very inconspicuous element in scientific research, whether in toxicology, nutrition or environmental science.
