内蒙古自治区饮用水中铀浓度初步调查

Survey of uranium concentrations in drinking water in Inner Mongolia autonomous region

目的 初步调查内蒙古自治区饮用水中的铀浓度,为当地居民健康保护和核应急评估等工作提供基础数据。方法 在2020-2022年枯水期和丰水期分别采集内蒙古自治区的12个盟市的旗(县、区)和嘎查(村)的自来水和井水样品,采集未过滤水样644份和过滤后水样34份,使用微量铀分析仪测量饮用水中铀浓度。结果 在枯水期和丰水期,自来水中铀浓度范围分别为0.85~23.61 μg/L和0.98~23.65 μg/L,井水中铀浓度范围分别为3.74~88.28 μg/L和3.68~95.36 μg/L。结论 初步掌握了内蒙古自治区饮用水中铀浓度水平,发现安装反渗透法的过滤装置可以显著降低饮用水中铀的含量。

Objective To investigate of the concentrations of uranium in drinking water in Inner Mongolia Autonomous Region for providing theoretical basis for the health protection of local residents and the assessment of nuclear emergency. Methods During the dry season and wet water season, tap water and well water samples were collected from 12 cities in Inner Mongolia, 644 unfiltered water samples and 34 filtered water samples were collected, and the uranium concentrations in drinking water was measured using a trace uranium analyzer. Results During dry and wet seasons the uranium concentration were 0.85-23.61 μg/L and 0.98-23.65 μg/L in tap water, 3.74-88.28 μg/L and 3.68-95.36 μg/L in well water, respectively. Conclusions The levels of uranium concentrations in drinking water in Inner Mongolia has been preliminarily ascertained, and the installation of filtration devices can significantly reduce the content of uranium in drinking water.
