Determination of total strontium in Uruguayan rice by inductively coupled plasma optical emission spectrometry (ICP-OES)
Resumen:
The alkali earth metal strontium has four naturally occurring isotopes: Sr-84, -86, -87, and -88. Twelve other isotopes are radioactive and Sr-90 (half-life 28.78 years) is of greatest importance. In 1986, the world's worst nuclear power accident occurred at Chernobyl in the former USSR (now Ukraine), introducing a large amount of 90 Sr into the environment Strontium -90 presents a health problem since its substitutes for calcium in bone, and prevents its removal from the body. Owing to its chemical and biochemical similarities to calcium, more than 99% of Sr is efficiently incorporated into bone tissue and teeth. Therefore, knowledge about total Sr in foods is of extreme importance to prevent and control contamination
