食物及根周土含氟量测定

Determination of Contents of Fluorine In Foods and Soil Round Their Roots

本文报告了1986～1989年没有氟污染的长丰、滨湖,逐丰、永丰、三工村(饮水含氟平均为0.21、0.54、1.12、2.47、3.72μg/L),采集食物及根周土各1220份。用保护性灰化、标准添加、电极法测定食物氟;电极法测定土壤溶解性氟。结果表明:食物含氟与根周土含氟没有显著的相关关系。当地产粮食、蔬菜不致成为地方性氟中毒的高氟来源。

This article reports that thene is no Fluorine pollution in Chang Fen,Bin Hu, Zhu Feng, yong Fen and San Gong Villages ( Their average contents of Fluorine in drinking water are 0.21, 0.54, 1.12, 2.47, 3.72μg/L ) fron 1988 to 1989. 1220 samples hane been collected in both foods and soil round their roots. It zhowed that thene is no relation between contents of fluorine in fooels and in soil round their roots by methods of the protectine incineration, the standard addition and electrade method to determine contents of fluorine in soils solubility. According to determining fluorine contents in foods.It proves that it is imporrible to become the high source of the endemic Fluorine poironing by eating foodls and vegetable in changji ne-gion.
