Endemic fluorine disease is a chronic fluorine poisoning caused by high level of fluorine in drinking water or foods. Incidence of this disease has been knowu in many parts of the world. In China its occurrence has been observed in the Northeast, Northwest, Southwest and some other localities. Investigation shows that it is closely related to geochemical environment: Major fluorine sources in nature include fluorinerich volcanic rocks, calcareous dolomites, phosphorus-bearing rocks/loess and Quarternary loose sediments. Under special conditions fluorine is concentrated in ground water or soil and seeks its way into human body through diet. Areas With high fluorine concentration responsible for the fluorine disease can be classified into four types, depending on characteristics of geochemical environment: (1) Arid and semiarid calcium-rich soda saline areas; (2) Semiarid, alternatively marine-terrestrial strata with a high degree of salinity; (3) Semihumid iron- and aluminum-rich intermediate-acid soils; (4) Localities where fluorine-rich rocks or deposits are developed;and those with high fluorine content as a result of industrial pollution. Based on medical statistics and chemical analyses, of water, soil, food and other related samplcs,this work will provide a scientific baekground for the prevention and control of fluorine disease.  相似文献   

Fluorosis and arsenicosis： An update     

Lakshmi Narasimharao Kodali Jagadiswararao Ramayanam 《中国地球化学学报》2006,25(B08):65-65

Endemic fluorosis, caused by excess fluoride in water, is widespread in the arid and semiarid tracts of India. This disorder is of recent origin and developed due to certain faulty water management practices. After Eager reported ‘dental mottling＇ among emigrants from Pozzuli in Italy in 1901, several such reports came from all over the world. From 3 works published independently from Pennsylvania, Arizona and South Africa in 1931, it was known that this disorder is caused by drinking water containing over 1 mg/L fluoride during formation of permanent teeth among children.‘Skeletal fluorosis/Osteofluorosis＇, affecting bones and joints among adults was reported by Moeller and Gudjonsson in 1932 due to accumulation of fluoride in hard tissues by drinking water with over 7 mg/L fluoride for several years. In course of time fluorosis has been reported in over 22 countries from all over the world. Fluorosis spreads now among 67 million people in the entire arid and semiarid tracts of India. The work of National Institute of Nutrition of India at Hyderabad in 1977 revealed the spread of endemic ‘genu valgum＇ （knock-knee） crippling lower limbs right from childhood in association with fluorosis in most parts of India. Although preliminary work revealed that genu valgum is caused by drinking waters poor in calcium and rich in molybdenum, efforts these disorders by supplying low-fluoride water should be taken up to know its exact cause to the communities could not so eradicate The governmental efforts to eradicate the problem.  相似文献   

保障饮水安全维护生命健康     

韩子夜 《水文地质工程地质》2005,32(4):i001-i001

我国是地方病流行较为严重的国家，地方病分布广泛，受害人口较多。由于自然环境影响。地方性砷中毒、地方性氟中毒、克山病、大骨节病以及地方性甲状腺肿等．在“老少边穷”地区及部分农村地区仍很严重。无疑，地方病严重影响了当地人民群众的生命健康和正常生活．并严重阻碍了建设小康社会的步伐。  相似文献

新疆境内地方病种类多、分布广、危害重。但属于水文地球化学成因的则主要有地甲、克汀、氟中毒、砷中毒和伽师病。地甲病遍布全疆,据1982年统计,85个县中仅有11个县患病率低于3%属非病区,其余的县分别属中、重、特重病区。地理位置几乎都在山前倾斜平原  相似文献

环境氟与人体健康——致世界卫生组织的一封公开信   总被引：5，自引：0，他引：5  

李端生 《吉林地质》2002,21(3):99-105

总结了环境中的氟与人体健康的关系。呼吁人们不可忽视微量元素氟对人体的生理功能，摄入不足轻则臻龋齿，重则导臻大骨节病的发生；在全面认识氟的基础上，发现了卤素和人体健康有氟主骨，氯主心，溴主神和碘主智的重要关系。同时提出“元素丰欠皆致病”和“多祛少补乃原则”的地方病发病机制和治疗原则；地方病的防治提倡食疗和饮疗，最后建议地方病以摄入的元素多少来命名，因为它既能反映致病原因，又明确了治疗方法，医患皆知。  相似文献

对邢台山前平原浅层高氟地下水中Ｆ，Ｃａ，Ｍｇ的组分存在形式与地方性氟病患病率之相关性研究结果表明，Ｆ，Ｃａ，Ｍｇ元素对地方性氟病之影响不仅取决于Ｆ，Ｃａ，Ｍｇ的总浓度，而且与各种元素在地下水中的组分存在形式密切相关。元素的给分存在形式不同，对地方性氟病的影响不也不。根据患病率与ａＭｇＦ＾＋成正相关，与ａＦ＾－／ａＭｇＦ＾＋成负相关，以及浅层高氟地下水中ＭｇＦ＾＋活度高的异常情况可以说明ＭｇＦ＾＋对  相似文献
