河北省沧州地区是新发生的地方性氟中毒重病区。从七十年代以来,本区大景开采深层地下水,当地人民喝上了淡水,但相继出现了氟中毒的现象。因此,研究并解除高氟水的危害,成了该地区人民的迫切要求,本文从水文地球化学的角度,初步探讨了沧州地区地下水中氟的成因及其富集规律,不妥之处,敬希指正。一、地下水中氟与相关离子的分布规律根据区内已有500多个地下水含氟量的测定资料表明,浅层淡水及成水中一般含氟最较低,而深层地下水含氟量较高。 1.浅层淡水地表以下30～40米的淡水,即第Ⅰ含水
Cangzhou in Hebei Province is a new endemic fluorosis area. Since the 1970s, deep water has been exploited in the great area of the area, and fresh water has been consumed by the local people. However, fluorosis has appeared one after another. Therefore, to study and remove the hazards of high-fluorine water has become an urgent requirement of the people in this region. This article has tentatively discussed the causes and enrichment rules of fluorine in groundwater in Cangzhou from the perspective of hydrogeochemistry. Hope correct. I. Distribution of Fluorine and Related Ions in Groundwater Based on the measured data of more than 500 fluorine contents in groundwater in the region, it shows that the fluorine content in shallow freshwater and into water is generally the lowest while the fluorine content in deep groundwater is high. 1. Freshwater below the surface of freshwater 30 to 40 meters, namely, the first water
