Study on Deep Groundwater with High-flouride in Lubei Plain
摘要
Abstract
In Lubei plain, long-term consumption of deep groundwater with high-flouride will cause endemic fluorosis, which affects the health of local people seriously.The enrichment of fluorine in groundwater is a complicated process.According to the analysis of samples, the content of flouride in deep groundwater takes on an ascend trend from south to north and from east to west in the study area.Even in the same position, the content of fluoride is not the same for different lithology.Content of fluoride in clay is higher than that in silty sand generally.High-flouride groundwater used to be weak alkalinity water, and the ratio of Na/Ca is higher.High-flouride water and the ratio of Na/Ca is a logarithm relation, and they correlated well.The hydrochemical type is generally HCO3·Cl-Na in high-flouride water.From the aspects of geological environment, hydrogeological environment and hydro geochemistry in Lubei plain, hydro-geochemical cause of underground with high-flouride in Lubei plain has been studied.It is concluded that the accumulation and distribution law of high-flouride water are mainly affected by depositional environment, runoff condition and yield.Such reasons make the content of fluoride rise gradually as different sources of sediments, different hydrochemical characteristics, exploitation of deeper groundwater which make the clay layer consolidated to release more water and the increase of clay layer in amount/total thickness from south to north resulting to slower groundwater runoff.All the reasons mentioned above lead to the quite different distribution characteristics of fluoride between south and north parts.关键词
