以日摄氟量作为评价环境氟对人体健康影响的指标,比单一用空气、饮水和食物等的含氟量进行分析要合理。日摄氟量的计算各家不一,我们是将各点大气、饮水、粮食、蔬菜的实测含氟量分别乘大气12m~3、饮水3L、粮食0.6kg、蔬菜0.5kg,其和即是。研究结果表明:(1)成人的尿氟与日摄量呈非常显著的正相关(r=0.8809,P<0.01)。(2)成人的牙齿,各调查点的斑釉率和斑釉指数均随日摄氟量的增加而上升,二者分别与日摄氟量呈高度显著和显著的正相关(r=0.9048,p<0.01;r=0.8154,p<0.05)。(3)成人的胫腓骨、尺挠骨和骨盆的X线改变,以骨质增生、骨质的密度、结构改变和骨周肌腱韧带附着处钙化为主要表现,其改变的总阳性率与日摄氟量有一定的关系。
Taking the daily fluoride intake as an index to evaluate the effect of environmental fluorine on human health, it is reasonable to analyze the fluoride content of air, drinking water and food, etc., separately. Calculate the amount of fluoride on a daily basis different from each other, we are the point of the atmosphere, drinking water, food, measured fluoride, respectively, by atmospheric air 12m ~ 3, drinking water 3L, grain 0.6kg, vegetable 0.5kg, and that is . The results showed that: (1) There was a significant positive correlation between urinary fluoride and daily intake of adults (r = 0.8809, P <0.01). (2) Adult teeth, spot glaze index and spot glaze index increased with the increase of daily fluoride exposure, both of which had a highly significant and significant positive correlation (r = 0.9048, p <0.01; r = 0.8154, p <0.05). (3) X-ray changes of tibiofibula, ulnar radius and pelvis in adults are mainly manifested as hyperplasia of bone, density of bone, structural change and calcification of peri-tendon ligament attachment. The total positive rate of change is similar to that of day Fluoride intake has a certain relationship.
