high-fluorine
1.Fluorosis is more common than arsenic poisoning because high-fluorine coal is combined with high-fluorine clay to make briquettes.
2.Hydro-geochemical Characteristics of Underground Water with High-fluorine in Southwest of Shandong Province
3.Investigation of Relationship between the Eruption of Deciduous Teeth and Rickets of Nursing Infants in High-fluorine Areas
5.In girls, the heights of 13-years old age group from high-fluorine area is shorter than the same age group from low-fluorine area and the difference is obvious(P<0.05).
6.In boys, the heights of 8-years old children from high-fluorine area is higher than the heights of children from low-fluorine area. The heights of 12-years old and 13-years old group from high-fluorine area is shorter than those of the same age group from low-fluorine area. The three different age groups showed great difference(P<0.05).
8.It is clarified that the Archean?Proterozoic ancient rock series with high fluorine in the Taishan?Yimenshan uplifted region is the material source of soil sediments,and that the Yellow River flood and heap many times (absorption of fluorine by clay minerals)accumulates and adds fluorine content in the soils according to heavy mineral comparative study and topography analysis.
9.Method The mice of test group drink waler with fluorine and the mice of control group drink running water. The significance test was conduced with the t-test . Result The results showed that the SCE frequency of the mice drinking high-fluorine water ware higher than those of control group and the difference was obvious(p <0.05) .
10.This paper describes the process for producing commercial beryllium oxide from non-beryl beryllium ore,especially the method for producing commercial beryllium oxide from high-fluorine beryllium ore and presents production situation of Shuikoushan commercial beryllium oxide.
