摘要
对中国19个城市的供水氟含量与当地居民尿氟含量进行了检测,并对检测当月的平均气候资料和口腔健康资料与之进行相关分析。研究表明,低于18℃的月平均气温对我国城市居民氟的摄入量基本没有影响;当月平均气温高于18℃时,随着气温的升高,我国城市居民氟的摄入量会随饮水量的增加而上升,反映了我国城市居民主要依靠饮用水摄取氟。对于平均相对湿度来说,月平均相对湿度超过80%会对我国城市居民氟的摄入量产生影响。
In this study fluorine concentrations of drinking water as well as urine of local residents in 19 cities were tested. The meteorological and dental health data were also collected. It has been proved that when air temperature is above 18℃,urban residents will intake more fluorine through drinking water with increasing temperature, when the temperature is below 18℃, no remarkable relationship will be observed between air temperature and the amount of fluorine intake, indicating that the main source of fluorine intake in China is tap water instead of foodstuff. In cities with the monthly average relative humidity exceeding 80%, the amount of fluorine intake will be affected.
