中文摘要:
      对淄博市重点区域地下水进行了总α、总β放射性水平调查。7个化工区总α、总β活度浓度均不超过《生活饮用水卫生标准》(GB 5749-2006)中总放射性指导值。Pearson相关性检验结果表明,水样残渣量与总α、总β活度浓度之间均呈现较强的正相关性(P<0.001),水体的总放射性随残渣量的增大而增大。溶解性总固体单项组分评价结果显示,112个地下水样品中无一符合Ⅰ类标准,Ⅱ类、Ⅲ类、Ⅳ类和Ⅴ类水质分别占6.25%、32.14%、42.86%和18.75%。地下水井水未经处理直接作为居民生活饮用水,反映出调查地区农村饮水安全工程建设工作有待进一步加强。地下水供水量占淄博市总供水量的50%以上,保护和合理开发利用地下水资源将是一项长期性任务。
英文摘要:
      The gross α and β radioactivity levels were investigated in the key regions of Zibo. Gross α and β activities in 7 chemical industry areas were lower than the guideline values recommended by Standards for Drinking Water Quality (GB 5749-2006). Results of Pearson correlation analysis showed that there was a strong positive correlation between the water residue and the gross α and β activity concentrations (P<0.001). Ground water with a large amount of residues were generally the most radioactive. The single component assessment of total dissolved solids showed that none of 112 groundwater samples belonged to class I. The proportions of the class Ⅱ, Ⅲ, IV and V were 6.25%, 32.14%, 42.86% and 18.75%, respectively. The direct use of untreated groundwater as the drinking water for residents reflects that the construction of the rural drinking-water safety project should be further strengthened in the investigating regions. In all, more than 50% of the water supply in Zibo is from ground water. The protection, reasonable exploitation and utilization of the groundwater resources will be a long-term task.
