- W2382772256 abstract "In the Lower Liaohe River Plain,182 groundwater samples were sampled and the concentrations of fluorine ion and other general components were analyzed. The results show that groundwater with fluorine concentrations over the national standard occur in the local areas. Through spatial variability analysis,the presence of fluorine ion can be described with the exponential model,indicating that the occurrence of fluorine is mainly caused by large-scale regional factors with a moderate spatial similarity. Hydrochemical analyses show that the high-fluorine groundwater occurs in the areas with weak bases and high bicarbonate concentrations,and the fluorine concentrations are not inversely proportional to calcium contents. Factor analyses show that three factors are identified for the hydrochemical type. F1 is the evaporation condensation factor,F2 is the p H and agricultural pollution factor,and F3 is the bicarbonate and fluorine natural geological environment pollution factor. The cause of the high-fluorine groundwater is mainly the effect of dissolution at the northern area of the plain and in the Linghe River alluvial fan. Through transportation and enrichment,fluorine shows high concentration in the shallow groundwater in the Xinmin and Linghai area. However,evaporation and agricultural pollution have not obvious influence on the groundwater in the coastal plain." @default.
