| Abstract: | 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. |

| Keywords: | endemic fluorosis regional differentiation safety threshold dose effect environmental risk assessment |
