北京市昌平区小汤山地区地热资源丰富,温泉水含氟量高,是较为典型的地热水和温泉高氟地区,居民长期饮用高氟水造成地方性氟中毒的流行,导致氟斑牙和氟骨症,曾是历史重病区。卫生部门从上世纪90年代开始监测学龄儿童氟斑牙患病情况,但是对于患病的本底数据,即改水前人群患病情况掌握的不够完整。本次调查的主要目的是了解改水前人群患病情况和目前的防治现状,评价本地区改水降氟的效果,为进一步巩固防治成绩提出建议。
The Xiaotangshan area in Changping District of Beijing is rich in geothermal resources and high in fluorine content in hot spring water. It is a typical geothermal water and hot spring high-fluoride area. The endemic fluorosis is caused by long-term consumption of high-fluorine water by residents, leading to dental fluorosis Fluorosis, was a history of serious illness. Health departments from the 90s of last century to monitor the incidence of dental fluorosis in school-age children, but for the prevalence of background data, that is, before the water diversion to grasp the situation is not complete enough.
