目的调查淄博市某石化产业聚集区地下水总α和总β放射性浓度水平,研究该区域地下水溶解性总固体变化规律。方法按照《生活饮用水标准检验方法放射性指标》(GB/T 5750.13-2006)国家标准方法和《生活饮用水标准检验方法感官性状和物理指标》(GB/T 5750.4-2006)溶解性总固体的测定称量法。结果三类地下水总α活度浓度范围分别为0.017~0.168、0.032~0.254、0.022~0.277 Bq/L,总β活度浓度范围分别为0.043~0.144、0.056~0.201、0.083~0.433 Bq/L;三类地下水溶解性总固体分别为423~945、490~1200、437~3321 mg/L。结论该石化产业聚集区地下水总α和总β活度浓度未超出《生活饮用水卫生标准》(GB 5749-2006)标准限值;地下水溶解性总固体部分超标,其中以工业水井水超标最明显。
Objective To investigate the total α and total β radioactive concentrations of groundwater in a gathering area of petrochemical industry in Zibo City and to study the variation law of total dissolved solids in groundwater in Zibo. Methods According to the national standard method of “Standard Test Method for Domestic Drinking Water” (GB / T 5750.13-2006) and “Sensory Traits and Physical Indicators of Standard Test Method for Domestic Drinking Water” (GB / T 5750.4-2006), the total dissolved solids Determination of weighing method. Results The total α activity of the three kinds of groundwater were 0.017-0.168, 0.032-0.254 and 0.022-0.277 Bq / L, respectively. The total β activity concentrations ranged from 0.043 to 0.144, from 0.056 to 0.201 and from 0.083 to 0.433 Bq / L, respectively. The total dissolved solids of the three types of groundwater were 423 ~ 945, 490 ~ 1200 and 437 ~ 3321 mg / L, respectively. Conclusions The total α and total β activity of groundwater in the agglomeration area of the petrochemical industry did not exceed the standard limit of “Sanitary Standard for Drinking Water” (GB 5749-2006); the total solid portion of groundwater dissolved exceeded the standard, .
