| 中文摘要 | The levels of fluorine in sediment cores obtained from Changyi County (PZ core) and Laizhou County (TS core) are used to discuss the fluorine sources in groundwater and its enrichment dynamics. The sediments in the aquifer are mainly constituted of granite gravels. The levels of fluorine in the PZ and TS cores range from 130 to 468 mg/kg, 139-528 mg/kg, with average values of 324, 348 mg/kg, respectively, which show relatively lower levels than the national average of fluorine in the soil or sediment. Thus, the fluorosis in this area should not be attributed to the levels of fluorine in sediments. The average fluorine concentrations in the aquifer from top to bottom are 154, 139, 200, 222 mg/kg for the TS core, and 154, 130, 266, 272 mg/kg for the PZ core, respectively, which are the lowest of the cores and extremely lower levels than the fresh granites. Such a fact indicates that a vast amount of fluorine has been leached into the groundwater. Moreover, the fluorine leachability is estimated to be approximately 70 %, although the previous documents showed fluorine contents of the granite surrounding Laizhou Bay were almost equal to or even lower than the average levels of fluorine in fresh granites. Meanwhile, a simulation experiment also reveals that fluorine release from rocks increases with the addition of seawater and brine water. Therefore, the seawater intrusion may potentially enhance the fluorine leachability, and should be an important dynamic of fluorine enrichment. |
