地方病是一种具有某种地域特征的特异性疾病。这类地域特征与某些环境化学元素分布不均衡有关,如某些元素过多、过少或比例失调,致使在该环境中生活的人群体内微量元素代谢不平衡而患病。地方性氟中毒就是由于人体长期接触环境中过量的氟引起的一种地球化学性疾病。这种疾病的发生具有明显的地域性。我国地方性氟中毒的病区主要有两种类型,一种是饮用高氟水而引起的饮水型病区;另一种是燃用高氟煤,污染室内空气和食物而引起的燃煤污染型病区。这两类病区具有明显的地域差异和独特的环境特征。为了进一步探讨我国地方性氟中毒的环境致病因素,笔者在过去工作的基
Endemic disease is a kind of specific disease with some regional characteristics. Such geographical features are related to the imbalanced distribution of some environmental chemical elements. For example, too many elements, too few or a certain proportion of them are imbalanced, resulting in imbalanced metabolism of trace elements in the population living in this environment. Local fluorosis is a geochemical disease caused by long-term human exposure to fluoride in the environment. The occurrence of this disease has obvious geographical. There are two main types of endemic fluorosis in our country. One is drinking-water ward caused by drinking high-fluorine water and the other is coal-burning pollution caused by burning high-fluorine coal, polluting indoor air and food Type ward. These two types of wards have obvious geographical differences and unique environmental characteristics. In order to further explore the environmental risk factors of endemic fluorosis in China, I work in the past based
