| A Tentative Discussion on the Control Factors of Iodine Content in Phreatic Water in Huaihe River Plains of Jiangsu Province |
| Based on an analysis of the distribution of iodine content in phreatic water, soil and hydrogeological conditions and land form, the authors have a new understanding on the control factors of iodine content in groundwater: The previous researchers hold that the iodine content in groundwater is proportional to the organic matter, whereas the authors consider that there is no fixed relationship between the iodine content and organic matter content in groundwater, but the organic matter contributes to the increase of water-soluble iodine content, and they are directly proportional in some areas. Groundwater flow conditions impact significantly the iodine content. The iodine content is often low and in compliance with drinking water standards in hilly land where the runoff conditions are better, whereas the iodine content often exceeds drinking water standards in low-lying areas of poor runoff conditions; The iodine content in groundwater is directly proportional to the content in soil under the same hydrogeological conditions. Another important feature of the iodine concentration in groundwater is that it is very stable and changes very little with time and mining activity. |
