且末县绿洲区地表水与地下水中硼的分布特征及其影响因素
Distribution characteristics and influencing factors of distribution of boron in surface water and groundwater in the oasis area of Qiemo County and factors influencing it
摘要
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 evalua-tions 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 con-structed,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 SO2-4 and Na+.There are many types of hydrochemistry,with surface water and groundwater main-ly 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 ex-cessive boron in the area,and show that the geological environment has a great influence on the accumulation of boron in water.关键词
