Iodine In Soil Map. However where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables iodine added to salt provides the small but essential amount needed by humans. For example it appears to play a role in immune response and might have a beneficial effect on mammary dysplasia and fibrocystic breast disease. Therefore we investigated iodide and iodate sorption by four different reference soils for contact times up to 30 days. Determination of the soil iodine content requires a sensitive analytical method because soils contain only 10 -1 mg kg -1 of iodine in the case of low concentration.
Iodine is a naturally occurring chemical element like oxygen and iron. Young author of Thyroid Guardian of Health Iodized salt is an important component to the American diet because much of the soil in the United States is deficient in iodine. Iodine binds to organic matter in the soil and also to some oxides of aluminium and iron. 320 141 pixels 640 283 pixels 1024 452 pixels 1280 565 pixels 2560 1130 pixels 940 415 pixels. In the case of the study areas except for the samples from non-farm lands the concentration of iodine. Of iodine appear to range from 01 to 15 ppm while anomalous concentrations appear to range from approximately 35 to 105 ppm which would be one to two standard deviations from the mean.
Atmospheric precipitation is by far the most important source of soil iodine Fuge and.
It should be noted that because an entire state is marked in red this does not indicate. One survey has been reported from the Thrace. Iodine surveys have been conducted in many regions of the US including. This map shows the areas in the United States where the soils are deficient in iodine. If the iodine is not bound to the soil a large fraction of added 129I is volatilised after a rather short period. It should be noted that because an entire state is marked in red this does not indicate.
