本文就我国目前试行的《地方性氟中毒防治工作标准》中所规定的氟病区划分方面的有关问题进行了研究和探讨,认为:《标准》中规定的轻病区(饮水含氟量在1.1—2.0mg/L)不应按病区对待,只视为是“氟斑牙流行区”,而将饮水含氟量为2.1—4.0mg/L 的地区定为轻病区,将4.1—7.0mg/L 的地区定为中病区,将7.1mg/L 以上地区定为重病区。氟病区的划分除考虑饮水含氟量这一因素外,其主要依据应为有无氟骨症及各型所占的比例。
In this paper, the current trial of “endemic fluorosis prevention and treatment of work standards,” the provisions of the fluorine ward division related issues were studied and discussed that: “standard” in the light ward (drinking water fluorine content in 1.1-2.0mg / L) should not be treated as a ward, only as a “dental fluorosis area”, and drinking water fluoride content of 2.1-4.0mg / L of the area as a light ward, the 4.1- 7.0mg / L as the ward area, 7.1mg / L above the area as a ward. In addition to considering the fluoride content of fluoride drinking water this factor, the main basis for the presence of fluorine-free bone and the proportion of each type.
