Distribution, occurrence mechanisms, and management of high fluoride levels in the water, sediment, and soil of Shahu Lake, China
Fluoride (F−) pollution is a serious global problem. However, relatively few studies have evaluated the occurrence mechanisms of F− from an entire lake system perspective and determined their major causes via quantitative analysis. This study analyzes the distribution and occurrence mechanisms of F−...

| 520 | |a Fluoride (F−) pollution is a serious global problem. However, relatively few studies have evaluated the occurrence mechanisms of F− from an entire lake system perspective and determined their major causes via quantitative analysis. This study analyzes the distribution and occurrence mechanisms of F− in the lake water, sediment, groundwater, and soil of Shahu Lake, as well as assessing the influence of the factors on the F− in the lake water via quantitative analysis. Our results show that the F− concentrations in groundwater are higher in the eastern area of the lake, which is different from that in the surface soil layer. The F− concentrations in the lake water vary from 0.95 to 1.40 mg/L, most of which exceed Chinese standards (1 mg/L). Groundwater F− concentrations at 35% of the sampling sites exceed 1 mg/L. The total F− in the soil is significantly higher than the global mean. Ca2+-deficiency (which is mainly accelerated by cation exchange between Ca2+ and Na+) together with alkaline water conditions and intense evaporation are the major contributors of F− enrichment in groundwater. The groundwater hydrochemistry is suitable for the dissolution of F−-bearing minerals. The F− in soil is not easily leached into groundwater. Approximately 6.96 t of F− is deposited into Shahu Lake annually, where 79.17% of the F− originates from water recharge. Evaporation is the main direct cause of high F− concentrations in the lake, whereas water recharge and obstructed surface water exchange are indirect causes. To effectively decrease the F− concentrations in the lake water, water exchange within the Shahu Lake system should be enhanced, or at least 4.42 million m3 of lake water should be pumped out of the system before anthropogenic water recharge, with identically increasing volumes. | ||

Ca2+-deficiency (which is mainly accelerated by cation exchange between Ca2+ and Na+) together with alkaline water conditions and intense evaporation are the major contributors of F− enrichment in groundwater. The groundwater hydrochemistry is suitable for the dissolution of F−-bearing minerals. The F− in soil is not easily leached into groundwater. Approximately 6.96 t of F− is deposited into Shahu Lake annually, where 79.17% of the F− originates from water recharge. Evaporation is the main direct cause of high F− concentrations in the lake, whereas water recharge and obstructed surface water exchange are indirect causes. To effectively decrease the F− concentrations in the lake water, water exchange within the Shahu Lake system should be enhanced, or at least 4.42 million m3 of lake water should be pumped out of the system before anthropogenic water recharge, with identically increasing volumes.

| abstract |
Fluoride (F−) pollution is a serious global problem. However, relatively few studies have evaluated the occurrence mechanisms of F− from an entire lake system perspective and determined their major causes via quantitative analysis. This study analyzes the distribution and occurrence mechanisms of F− in the lake water, sediment, groundwater, and soil of Shahu Lake, as well as assessing the influence of the factors on the F− in the lake water via quantitative analysis. Our results show that the F− concentrations in groundwater are higher in the eastern area of the lake, which is different from that in the surface soil layer. The F− concentrations in the lake water vary from 0.95 to 1.40 mg/L, most of which exceed Chinese standards (1 mg/L). Groundwater F− concentrations at 35% of the sampling sites exceed 1 mg/L. The total F− in the soil is significantly higher than the global mean. Ca2+-deficiency (which is mainly accelerated by cation exchange between Ca2+ and Na+) together with alkaline water conditions and intense evaporation are the major contributors of F− enrichment in groundwater. The groundwater hydrochemistry is suitable for the dissolution of F−-bearing minerals. The F− in soil is not easily leached into groundwater. Approximately 6.96 t of F− is deposited into Shahu Lake annually, where 79.17% of the F− originates from water recharge. Evaporation is the main direct cause of high F− concentrations in the lake, whereas water recharge and obstructed surface water exchange are indirect causes. To effectively decrease the F− concentrations in the lake water, water exchange within the Shahu Lake system should be enhanced, or at least 4.42 million m3 of lake water should be pumped out of the system before anthropogenic water recharge, with identically increasing volumes. |

The groundwater hydrochemistry is suitable for the dissolution of F−-bearing minerals. The F− in soil is not easily leached into groundwater. Approximately 6.96 t of F− is deposited into Shahu Lake annually, where 79.17% of the F− originates from water recharge. Evaporation is the main direct cause of high F− concentrations in the lake, whereas water recharge and obstructed surface water exchange are indirect causes. To effectively decrease the F− concentrations in the lake water, water exchange within the Shahu Lake system should be enhanced, or at least 4.42 million m3 of lake water should be pumped out of the system before anthropogenic water recharge, with identically increasing volumes.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Hydrogeochemistry</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Fluoride</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Water recharge</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Occurrence mechanisms</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Lake system</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Environmental management</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Xiang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Longmian</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Peng, Fuquan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pang, Qingqing</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">He, Fei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xu, Bin</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier Science</subfield><subfield code="a">Li, Xueqing ELSEVIER</subfield><subfield code="t">Efficient photocatalytic hydrogen peroxide production induced by the strong internal electric field of all-organic S-scheme heterojunction</subfield><subfield code="d">2022</subfield><subfield code="d">journal of the International Association of Geochemistry and Cosmochemistry</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV009019316</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:126</subfield><subfield code="g">year:2021</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.apgeochem.2021.104869</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">35.18</subfield><subfield code="j">Kolloidchemie</subfield><subfield code="j">Grenzflächenchemie</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">126</subfield><subfield code="j">2021</subfield><subfield code="h">0</subfield></datafield></record></collection>
