摘要
淮河流域盱眙段浅层地下水的45个监测点水质分析表明,本区浅层地下水氟含量较低,平均值在0.412 mg/L,为低氟水;沿淮河方向,浅层地下水氟含量总体有降低的趋势,但变化幅度小;垂直河流方向氟含量总体表现出距淮河越远有增高的变化趋势;其成因主要与本区水文地球化学条件、气候因素及地下水径流条件有关。下游低氟区需要注意在饮食中适量补充氟。
45 samples in shallow groundwater in Xuyi County were collected and analyzed. The results showed that the concentration of fluoride in the shallow groundwater was 0. 412 mg/L on the average, which belongs to a low-fluorine water, The concentration of fluoride ion in shallow groundwater in this region was proportional to the distance from the Huaihe River, and the river had a greater impact on the content of fluoride ion in shallow groundwater near riparian areas. Climatic conditions, the nature of rock, the acidity and conductivity of groundwater, the oxidation and reduction environment of groundwater, and the runoff conditions of groundwater were the main causes of low--fluorine.
