调查了典型饮水型氟中毒流行区4个不同氟暴露水平地区的人群氟中毒和儿童龋齿患病率,并研究了它们与饮水氟浓度及总摄氟量的关系。提出了我国北方农村的适宜、安全饮水氟浓度分别为0.95mg/L和1.21mg/L;7~15岁儿童适宜、安全总摄氟量为1.9mg和2.1mg/(人·日);成人最大安全总摄氟量为3.4mg/(人·日)。该项研究还对饮水氟和总摄氟量造成的氟中毒的危险性进行了评价。
The prevalence of fluorosis and caries in four population with different levels of fluoride exposure in a typical drinking water fluorosis area was investigated and their relationship with fluorine concentration in drinking water and total fluoride exposure was also investigated. The suitable and safe drinking water fluoride concentrations in the northern rural areas of China were 0.95mg / L and 1.21mg / L, respectively. The appropriate dosage for children aged 7-15 years was 1.9mg and 2.1mg / Day); the maximum safety of adult maximum total fluoride intake of 3.4mg / (person · day). The study also evaluated the risk of fluorosis due to drinking water fluoride and total fluoride exposure.
