甘肃省地方性氟中毒流行概况及防制对策

目的 提出甘肃省地方性氟中毒防治对策。方法 按《地方性氟中毒防治手册》进行。结果甘肃省地方性氟中毒属我国北方典型的干旱、半干旱饮水型地方性氟中毒病区，病区分布：河西走廓高氟区；陇中黄土高原高氟区；高氟温泉、矿泉点。针对不同病区，全省以打深井，引江河水、水窖为主要防制手段。已建成的改水工程，有效地控制了地氟病的发生和流行，但据我们调查改水工程，水氟含量超标占６０％以上，报废停用占５０％以上，能坚持学

Epidemic situation and preventive stratagy of endemic fluorosis in Gansu province

Objective To propose suitable prevention measures for endemic fluorosis.Methods Abide by the Endemic Fluorosis Prevention Manual.Results Endemic fluorosis of Gansu province is typical drinking water region of north China.Endemic fluorosis region distribution:The fluoride high region of the west River Passageway;fluoride high region of plateau in mid Gansu and hot spring.Major prevention measures are deep well,drawing river water and storage water cellgar.Keep on drinking fluoride low water,the water induced fluorosis will be effectively controlled.According to our investigation,the content of water fluoride by over 60% altering water resources works have exceeded quota.Over 50% works have been discarded as useless, 1/3 works could be used throughout year.Conclusions To increase income and strengthen administer are tasks which brooks no delay.
