摘要: 新疆且末县绿洲区存在高硼地表水和地下水,严重影响居民身体健康。为初步探明且末县绿洲区水化学特征及硼的主要来源,2023年共采集了24组水样(4组地表水、20组地下水),运用Piper三线图、Gibbs图,相关性分析、氢氧同位素、APCS-MLR(绝对主成分-多元线性回归)模型等方法对且末县绿洲区地表水与地下水的水化学特征及其硼的来源进行初步分析,定量评估了不同因子对水中硼和其他水化学组分的贡献。结果表明:(1) 且末县绿洲区地表水与地下水整体呈弱碱性,pH均值为8.22,地下水主要为微咸水,阴阳离子主要为SO42-、Na+。(2) 水化学类型较多,地表水和地下水均以SO4·Cl-Na·Mg型为主。(3) 研究区内地表水中硼的均值为2.34 mg·L-1,超标率为100%;地下水中硼的均值为1.73 mg·L-1,超标率为70%。(4) APCS-MLR受体模型分析揭示了水化学组分及硼的来源主要有溶滤-富集因子(F1:58.21%)、原生地质因子(F2:15.42%)、人类活动因子(F3:11.18%)和未知源。区内水中硼超标现象明显,地质环境对水中硼的富集具有较大影响。

Abstract:

There are high levels of boron in surface water and groundwater in the oasis area of Qiemo County, Xinjiang, which seriously affects the health of residents. To clarify the chemical characteristics of the oasis water and the main source of the boron, 24 groundwater samples from each of 20 locations were collected in 2023. They were then analyzed using a Piper three-line plot, Gibbs diagram, and correlation analysis, along with evaluations of hydrogen-oxygen isotopes. An APCS-MLR (absolute principal component-multiple linear regression) model of the chemical characteristics of surface water and groundwater and the source of the boron was also constructed, as well as quantitative evaluation of the contribution of different factors to water boron levels and other hydrochemical components. The results showed that the surface water and groundwater in the oasis area of Qiemo County are weakly alkaline, the mean pH is 8.22, the groundwater is mainly brackish water, and the anode ions are mainly S O 4 2 -and Na+. There are many types of hydrochemistry, with surface water and groundwater mainly containing SO4·Cl-Na·Mg. The mean level of boron in the surface water in the study area was 2.34 mg·L-1, with an exceeding rate of 100%; meanwhile, the corresponding value in the groundwater was 1.73 mg·L-1, with an exceeding rate of 70%. APCS-MLR receptor model analysis revealed that the hydrochemical components and boron sources were mainly soluble filter-enrichment factors (F1: 58.21%), native geological factors (F2: 15.42%), human activity factors (F3: 11.18%), and unknown sources. These findings clarify the cause of the excessive boron in the area, and show that the geological environment has a great influence on the accumulation of boron in water.
