近几年来,国内有报告说水氟或土壤氟能明显提高植物和粮食含氟量,有的被作为对自来水加氟防龋提出异议的依据之一,为此,我们利用广东省丰顺县和河源县两个天然氟区,对这些关系进行了调查。这两个天然氟区属亚热带丘陵地,气候湿润,都有高氟温泉水,地表土层被浸染。年平均气温约21℃,居民饮用数米深的浅井水,以大米和甘薯为主粮。
In recent years, China has reported that fluorine or soil fluoride can significantly increase the fluoride content of plants and grains, and some have been used as a water fluoride fluoride anti-caries objections based on one of the reasons, we use the Guangdong Province Fengshun County And Heyuan County, two natural fluorine area, conducted a survey of these relations. These two natural fluorine areas are subtropical hilly areas with humid climates and high-fluoride hot spring water. The surface soil is soaked. The average annual temperature is about 21 ℃, residents drink shallow wells several meters deep water, mainly rice and sweet potato.
