The aim of the research was to study and compare iodine concentration in natural waters originating from aquifers of different ages, primarily residents use for drinking purposes. The analysis was based on the original data on the samples collected during the fieldwork in the Bryansk region (2013-2017) and in the Oryol region (2016-2017). In addition to iodine concentration, the main geochemical parameters (salinity, etc.) were determined in the selected waters. The results showed a significant variation of iodine in waters from both regions (Bryansk region-from 0.7 to 41.2 µg/l; Oryol region-from 1.12 to 36.8 µg/l), the difference being apparently due to different ages and origins of the sampled aquifers (Quaternary, Upper Devonian and Cretaceous deposits). The overall low provision of surface water with iodine was found both in the Bryansk region (median for shallow wells-5.82 µg/l, median for surface water-6.76 µg/l) and in the Oryol region (median for shallow wells-2.96 µg/l, median for surface water-7.4 µg/l). The data obtained deserve attention during organization of monitoring and implementation of measures preventing thyroid diseases.
该研究的目的是研究和比较源自不同年代含水层的天然水中的碘浓度，这些水主要供居民饮用。分析基于在布良斯克地区（2013 - 2017年）和奥廖尔地区（2016 - 2017年）实地考察期间采集的样本的原始数据。除了碘浓度外，还测定了所选水体中的主要地球化学参数（盐度等）。结果表明，两个地区水体中的碘含量存在显著差异（布良斯克地区为0.7至41.2微克/升；奥廖尔地区为1.12至36.8微克/升），这种差异显然是由于采样含水层（第四纪、上泥盆统和白垩纪沉积物）的年代和来源不同所致。布良斯克地区（浅井中位数为5.82微克/升，地表水中位数为6.76微克/升）和奥廖尔地区（浅井中位数为2.96微克/升，地表水中位数为7.4微克/升）的地表水碘含量总体较低。在组织监测和实施预防甲状腺疾病的措施时，所获得的数据值得关注。
