摘要
福州市区温泉型地方性氟中毒病区呈点状分布,范围局限,明显不同于我国北方氟中毒病区片状的分布。本文从水文地质方面分析我省温泉型氟中毒点状病区的成因,为改换水源降低水氟含量的预防措施提供科学依据。
Fuzhou has a great area of hot spring,which accounts for almost one seventh of the city.We sur- vey the fluorine content of 15 drinking water wells in fluorosis neighbourhood committee in hot spring region,8 wells exceed hygiene standard,and 7 wells don’t exceed.The distance between high fluorine well and low one is so close,some only 50m.This is the causes of ftuorosis area likes a dot distribu- tion.We analyze the condition by hydrology and geology.The dot like distribution of fluorosis makes that the preventive measures is easy to carry out by cut down water fluorine taking.
