Geochemistry of Iodine with special reference to Bihar state of India.

Iodine deficiency is an important global health problem. 8 person out of every hundred, suffer from goiter in India. by Dr. Nitish Priyadarshi Halogens are present and are volatile trace elements in most geological samples. Among them, iodine has the lowest abundance; less than 0.1 ppm in igneous rocks and less than several ppm in sedimentary rocks. Iodine is least abundant of the halogens and is lithophile element. It is typically a dispersed element and is never concentrated enough in rocks or sediments to form independent minerals. The content of iodine is higher in air masses of marine origin than in those over the continents (Rankama and Sahama, 1950). The content of iodine seems to have some relationship to the salinity of the sea water as it is found to increase to the rise in salinity. Iodine is carried away from the atmosphere partly by rainwater and partly by direct adsorption into the soil and into plants. High solubility of iodine makes it enriched in soil and its highest c...
