BACKGROUND The East African Rift Valley (EARV) area is characterized by an intense volcanic activity, which largely influences the nature of soils, ground and surface waters causing a transfer of fluoride from volcanic emissions to the environment. Field experiments were conducted in F-contaminated areas of Ngarenanyuki (Arumeru district) in North Tanzania. In order to evaluate the potential fluoride exposure from the diet and the related health risk for the local population, the content of fluoride in soil and plant tissues was assessed, focusing on the edible portions (leaves, fruits or seeds) of the main cultivated and consumed food crops in the area. RESULTS Average fluoride contents of 8.0, 11.4, 11.3 and 14.2 mg kg-1 of dry matter were observed respectively for maize (Zea mays L.), tomato (Lycopersicon esculentum Mill.), bean (Phaseolus vulgaris L.) and kale (Brassica sp. pl.) edible parts. The cumulative estimated average daily dose (EADD) ranged from 0.026 to 0.165 mg F d-1 kg-1 among different rural population groups and considering two different hypotheses of absorption fraction (75% or 100%), i.e. the amount of fluoride that is absorbed during the digestion process. The associated hazard index (HI) values varied from 0.43 to 2.75. CONCLUSIONS Considering the dietary habits of the local population, the outcomes of the present study suggest that the investigated crops can substantially contribute to fluoride related diseases, especially in earlier ages.

在富含氟的土壤中生长的粮食作物的氟化物吸收和转运

背景东非大裂谷(EARV)地区的特点是火山活动剧烈,这在很大程度上影响了土壤、地下水和地表水的性质,导致氟化物从火山排放物转移到环境中。田间试验在坦桑尼亚北部 Ngarenanyuki(Arumeru 区)受 F 污染的地区进行。为了评估饮食中潜在的氟化物暴露以及当地居民的相关健康风险,我们评估了土壤和植物组织中氟化物的含量,重点是主要栽培和植物的可食用部分(叶子、果实或种子)。消耗了该地区的粮食作物。结果 分别观察到玉米 (Zea mays L.)、番茄 (Lycopersicon esculentum Mill.)、干物质平均氟化物含量为 8.0、11.4、11.3 和 14.2 mg kg-1。豆 (Phaseolus vulgaris L.) 和羽衣甘蓝 (Brassica sp. pl.) 可食用部分。考虑到两种不同的吸收率假设(75% 或 100%),即吸收的氟化物量,不同农村人群的累积估计平均日剂量 (EADD) 范围为 0.026 至 0.165 mg F d-1 kg-1在消化过程中被吸收。相关的危险指数 (HI) 值从 0.43 到 2.75 不等。结论 考虑到当地人口的饮食习惯,本研究的结果表明,所调查的作物可能会导致氟化物相关疾病,尤其是在早期。本文受版权保护。版权所有。165 mg F d-1 kg-1 在不同农村人群中,并考虑吸收分数(75% 或 100%)的两种不同假设,即在消化过程中吸收的氟化物量。相关的危险指数 (HI) 值从 0.43 到 2.75 不等。结论 考虑到当地人口的饮食习惯,本研究的结果表明,所调查的作物可能会导致氟化物相关疾病,尤其是在早期。本文受版权保护。版权所有。165 mg F d-1 kg-1 在不同农村人群中,并考虑吸收分数(75% 或 100%)的两种不同假设,即在消化过程中吸收的氟化物量。相关的危险指数 (HI) 值从 0.43 到 2.75 不等。结论 考虑到当地人口的饮食习惯,本研究的结果表明,所调查的作物可能会导致氟化物相关疾病,尤其是在早期。本文受版权保护。版权所有。结论 考虑到当地人口的饮食习惯,本研究的结果表明,所调查的作物可能会导致氟化物相关疾病,尤其是在早期。本文受版权保护。版权所有。结论 考虑到当地人口的饮食习惯,本研究的结果表明,所调查的作物可能会导致氟化物相关疾病,尤其是在早期。本文受版权保护。版权所有。
