地方性氟中毒是我国分布较广,危害较大的一种地方病。现已查明,全国除上海市以外,其它28个省区市都分布有程度不同的病区,台湾也有。大量的调查表明,我国病区的主要类型有饮水型(包括来自浅层地下水,深层地下水、泉水)和生活用煤污染型(包括受氟污染的空气和粮食、蔬菜等食物)。此外还有因饮茶和用高氟食盐而导致出现氟中毒病区的报道。关于地方性氯中毒的科研、防治工作,近年来虽然已取得了很大的进展,但仍存在着不少亟待阐明和解决的问题,有的问题还有争议。比如我国南方一些病区的氟来源及其作用途径问题,氟的作用阈浓度及其卫生标准问题,以及发病机理,氟骨症的诊断依据和标准(包括临床、X 线、检验等)、更有效的防治方法和食品氟等的检测技术等等。为了进一步推动本病防治科研工作的深入开展,本期集中地编排了一组有关地方性氟中毒的专题笔读。关于专题笔谈,我们还是第一次尝试,对此还缺乏经验,无论在选题上或内容写法上肯定还有不少缺点。但是我们希望这种刊出形式对读者能够确实有所帮助,工作上能够有所借鉴。如果是这样的话,那么今后我们不仅办地氟病的,而且也办其它地方病种的。希望地方病防治科研人员对这种办刊形式多提意见,踊跃供稿,共同把本刊办得更加实用,以更好地为地方病防治科研服务。 Endemic fluorosis is a endemic disease that is widely distributed and harmful in China. It has been found that in addition to Shanghai, the rest of the 28 provinces, autonomous regions and municipalities in the country all have wards of varying degrees, and Taiwan also has them. A large number of surveys show that the main types of ward in our country are drinking water (including from shallow groundwater, deep groundwater and spring water) and living coal pollution (including air contaminated with fluorine and food such as grain and vegetables). In addition there are reports of fluorosis caused by drinking tea and drinking high fluoride salt. In recent years, great progress has been made in the scientific research and prevention and control of endemic chlorine poisoning. However, there are still many problems to be elucidated and solved urgently. Some issues are still debated. For example, some wards in southern China, the source of fluoride and its role in ways, the threshold concentration of fluoride and its health standards, as well as the pathogenesis of skeletal fluorosis diagnostic criteria and standards (including clinical, X-ray, test, etc.) Effective control methods and food fluorine detection technology and so on. In order to further promote the prevention and treatment of this disease in-depth development of scientific research, the current focus on the preparation of a series of thematic fluorosis reading. On the topic of writing, we are the first attempt, which is still lack of experience, both in the selection of topics or content, there are certainly many shortcomings. However, we hope this type of publication will really help the readers and help them learn from their work. If so, then in the future we will not only cure the disease, but also do other endemic diseases. It is hoped that researchers in endemic diseases prevention and treatment will make more comments on this type of publication and actively contribute articles so as to make it more practical to better serve the endeavor prevention and treatment of scientific research.
