水-岩(土)间氟迁移释放的影响因素分析
|
摘要
氟是人体的重要微量元素之一,对平衡人体机能具有重要作用。随着近年来饮水型氟中毒现象的加重,研究水-岩(土)间氟迁移释放规律具有重要意义。本文对水-岩(土)作用过程中氟迁移释放影响因素进行综合分析;地下水中的氟主要来自岩(土)中的含氟矿物,不同岩(土)氟含量深刻影响地下水氟含量;地下水高TDS、高pH、Na+、Mg2+、CO32-、HCO3-、高温度等对地下水中氟富集具有显著的促进作用。一些特殊地球化学过程如海水入侵、特殊气候条件对地下水氟富集具有明显的影响。地下水氟富集是多因子共同作用的结果,且不同的环境下影响因素也不相同。
Fluorine is one of the important trace elements in human body, which plays an important role in maintaining human function. With the aggravation of drinking-water fluorosis in recent years, it is significant to detect the laws of fluorine migration and release during water-rock interaction. The influencing factors of fluorine migration and release during water-rock(soil) interaction are comprehensively analyzed. The groundwater fluorine mainly origins from the fluorine-bearing minerals in rocks(soil), and the fluorine contents in different rocks(soil) have profound impact on the groundwater fluorine levels. High TDS, pH, Na+, Mg2+, CO32-, HCO3-, and temperature in groundwater significantly promote fluorine enrichment in groundwater. Some special geochemical processes, such as seawater intrusion and special climatic conditions, have also obvious effect on groundwater fluorine enrichment. Groundwater fluorine enrichment is the results of multiple factors, and the influencing factors differ under different environments.
