中文摘要 |
概述了我国地方性氟中毒的4个流行区域及其环境特征,揭示地方性氟中毒的流行与地球化学环境密切相关,研究了不同氟中毒病区氟从外环境到人体的传输途径及其剂量-效应关系.选择氟斑牙检出率5%作为病区划分标准,确定了不同病区环境氟的安全阈值,为氟的环境风险评价提供科学依据. |
英文摘要 |
Four endemic fluorosis regions in China and their environmental epidemiological characteristics were summarized in this paper. It shows that the epidemiology of endemic fluorosis is closely related to geochemica parameters of local environment. The food web and dose effect relationship of fluoride from environment to human body in different types of endemic fluorosis regions were studied. And the safety threshold of fluoride in different regions was determined. The results have provided a scientific basis for environmental risk assessment of fluoride in China. |
