摘要
河北平原东部第四纪更新世沉积环境决定本区地下水为氟离子富集区。加之地下水严重超采,吸附于粘性土氟离子随着释水进入地下水中,致使地下水含量不断增高。
The high concentration of fluorine anion in groundwater is determined by the Pleistocene sedimentary environment in east Hebei plain. Owing to the severe over-extraction of groundwater, the fluorine anion adhered to the cohesive soil grains are released into the groundwater. This causes the fluorine content in groundwater rising continually.
