Abstract
Strontium is a kind of trace element. Groundwater containing strontium is called mineral water when its content reaches a level that is beneficial for human physiology. Some groundwater resources in Shijiazhuang are rich in strontium. In this study, groundwater samples collected from 103 sites were studied for the hydrochemical characteristics of strontium and its formation mechanism in the groundwater system in Shijiazhuang City. The methods of source provenance analysis, factor correlation analysis, and runoff condition analysis were carried out in the study. The results showed that the content of strontium in eastern Shijiazhuang is higher than 0.229 mg/L, with a maximum content of 1.942 mg/L. The source of strontium is the dissolution of strontium-containing minerals in carbonate rock, sheet hemp rock, clastic rock, and granite in the Taihang Mountain area of the Hutuo River Basin. Strontium is positively correlated with total dissolved solids, bicarbonate, calcium magnesium, and free carbon dioxide. The erosion ability of groundwater strengthens the dissolution of strontium, and the geochemical action is mainly due to the dissolution. The enrichment and distribution of strontium are related to the conditions of groundwater runoff. Areas with good runoff conditions and strong mining are low in strontium, while areas with poor runoff conditions have high strontium content.
Highlights
Strontium is an alkaline-earth element, and its average abundance in the continental crust is 350 ppm [1]
Excessive sodium in the body can cause hypertension and cardiovascular diseases, while strontium can reduce the absorption of sodium in the human body. erefore, strontium has the effect of preventing these diseases [3]. us, the exploitation of natural strontium mineral water from available sources is of great importance
(2) Strontium content is positively correlated with the contents of dissolved total solids, bicarbonate, calcium, magnesium, free carbon dioxide, and metasilicic acid in the study area
Summary
Strontium is an alkaline-earth element, and its average abundance in the continental crust is 350 ppm [1]. Its elemental abundance varies among different types of magmatic rocks and sedimentary rocks. Gypsum and phosphorous block rocks have the highest abundance of Sr. ere are more than 30 kinds of strontiumbearing minerals in nature. Metasilicate mineral water, and carbonated mineral water are the main types of natural mineral water used for drinking in China. Strontium mineral water is distributed all over the country and is mainly found in Jilin, Shanxi, Jiangsu, Sichuan, and other regions. E function of strontium in the human body is mainly related to the formation of bones, and it is a normal component of human bones and teeth. Us, the exploitation of natural strontium mineral water from available sources is of great importance Excessive sodium in the body can cause hypertension and cardiovascular diseases, while strontium can reduce the absorption of sodium in the human body. erefore, strontium has the effect of preventing these diseases [3]. us, the exploitation of natural strontium mineral water from available sources is of great importance
