The north east of Tunisia ore deposits (Hammam Zriba) contain a large amount of fluorides constituting a risk of environmental pollution as well as risks to human and animal health. The aim of our work was to assess the levels of fluorides in the water and blood of sheep in the east of Tunisia region. This analysis study included 78 water samples and 60 blood samples taken during 3 days in the year 2019, from a sheep herd at Hammam Zriba delegation. The determination of fluorine concentration in the samples was carried out by potentiometry with a selective electrode type ISE combined Fluoride perfectION™. High Fluoride concentrations were found at a mean of 1.62 ± 1.18, 1.45 ± 0.98, and 2.65 ± 1.61 mg/l, respectively, in running, deep, and stagnant waters. In addition, 83.3% of the animals reared within 400 m of the study area had elevated fluoride levels in the blood exceeding the usual values (fluoremia> 0.15 mg/l). The concentration of fluoride in the blood of the animals decreases with increasing distance from the mine.
突尼斯东北部的矿床（哈马姆兹里巴）含有大量氟化物，对环境污染以及人类和动物健康构成风险。我们工作的目的是评估突尼斯东部地区绵羊的水和血液中的氟化物水平。这项分析研究包括2019年3天内从哈马姆兹里巴代表团的一个羊群采集的78份水样和60份血样。使用选择性电极类型ISE组合Fluoride perfectION™通过电位测定法对样品中的氟浓度进行测定。在流动水、深井水和滞水中分别发现高氟浓度，平均值分别为1.62±1.18、1.45±0.98和2.65±1.6I毫克/升。此外，在研究区域400米范围内饲养的动物中，83.3%的动物血液中的氟化物水平升高，超过正常值（血氟>0.15毫克/升）。动物血液中的氟化物浓度随着与矿山距离的增加而降低。
