大量研究结果证实，人体摄入的碘80%以上来自于食品，因此，碘缺乏病病区的形成应归因于植物含碘量的区域性差异。植物中的碘来自于大气和土壤，至今科学尚不能搞清在不同情况下，哪一部分碘占据主要部分。土壤中的碘与成土母岩中的碘含量基本无关，土壤碘含量主要决定于母岩风化产物对大气干湿沉降碘的吸收和保持能力。限于植物和大气中碘测定的困难，在碘的地球化学与碘缺乏病病区成因的问题上，目前仍有许多未解之谜。笔者提出，土壤中某种形态的碘可能以气态挥发并在近地大气层富集，存在植物吸收利用这一部分碘的条件的地区，不会有碘缺乏病的流行。

Many previous studies have demonstrated that food supplies more than 80% of total iodine intake of human being. Therefore, the development of iodine deficiency disorders (IDD) is a result of various iodine content of different territorial plants. Iodine in plants is from atmosphere and soils, but it is still uncertain that which one is the main source under the various conditions. Iodine content in soils is not determined by the iodine content in the parent rocks but their weathering offspring’s absorption and preservation of the iodine of the dry and wet precipitation from atmosphere. Because it is difficult in analyzing iodine in plants and atmosphere, there are lots of puzzles in the geochemistry of iodine and the causes of IDD development. A possibility of certain speciation of iodine vaporizing and accumulating at the low altitude atmosphere from the soils is proposed. No IDD occurs in the region where plants have the ability to absorb the iodine from low altitude atmosphere.
