The contents of. soil total fluorine (TF) and water-soluble fluorine (WF) were measured in fluorite ore areas located in Jinhua City. The single factor index, geoaccumulation index and health risk assessment were used to evaluate fluorine pollution in soil in four fluorite ore areas and one non-ore area, respectively. The results showed that the TF contents in soils were 28. 36-56 052. 39 mg.kg-1 with an arithmetic mean value of 8 325.90 mg.kg-1, a geometric mean of 1 555. 94 mg.kg-1, and a median of 812. 98 mg.kg-1. The variation coefficient of TF was 172. 07% . The soil WF contents ranged from 0. 83 to 74. 63 mg.kg-1 with an arithmetic mean value of 16. 94 mg.kg-1, a geometric mean of 10. 59 mg.kg-1, and a median of 10. 17 mg.kg-1. The variation coefficient of WF was 100. 10%. The soil TF and WF contents were far higher than the national average level of the local fluorine epidemic occurrence area. The fluoride pollution in soil was significantly affected by human factors. Soil fluorine pollution in Yangjia, Lengshuikeng and Huajie fluorite ore areas was the most serious, followed by Daren fluorite ore area, and in non-ore area there was almost no fluorine pollution. Oral ingestion of soils was the main exposure route. Sensitivity analysis of model parameters showed that children's weight exerted the largest influence over hazard quotient. Furthermore, a significant positive correlation was found among the three kinds of evaluation methods.
对金华市萤石矿区土壤中的全氟（TF）和水溶性氟（WF）含量进行了测定。分别采用单因素指数、地累积指数和健康风险评估法对4个萤石矿区和1个非矿区土壤中的氟污染状况进行了评价。结果表明，土壤中TF含量为28.36～56052.39mg·kg-1，算术平均值为8325.90mg·kg-1，几何平均值为1555.94mg·kg-1，中位数为812.98mg·kg-1。TF的变异系数为172.07%。土壤WF含量为0.83～74.63mg·kg-1，算术平均值为16.94mg·kg-1，几何平均值为10.59mg·kg-1，中位数为10.17mg·kg-1。WF的变异系数为100.10%。土壤TF和WF含量远高于当地氟病区的全国平均水平。土壤氟污染受人为因素影响显著。杨家、冷水坑和花街萤石矿区的土壤氟污染最为严重，其次是大仁萤石矿区，非矿区几乎不存在氟污染。经口摄入土壤是主要暴露途径。模型参数敏感性分析表明，儿童体重对危害商数的影响最大。此外，三种评价方法之间存在显著正相关。
