目的探讨农村散在井水高氟的原因。方法 2008-2012年福清市居民自发送检的2 113份井水检测资料,按井的深浅、分布地点及氟化物检测结果进行分类统计。结果在送检的2 113份井水中,深井水296份,氟含量超标率18.9%,而其所在的村庄浅井水含氟量正常。1 817份浅井水,含氟量超标率0.9%。深井水氟含量超标率高于浅井水。结论由于地质原因,福清市农村有些深井水存在高氟危害,建议采取改换水源等方法处置。
Objective To explore the causes of high fluoride in scattered well water in rural areas. Methods A total of 2 113 well water samples sent by Fuqing residents from 2008 to 2012 were collected and classified according to the depth of the well, its distribution location and the fluoride test results. Results Among the 2 113 wells that were submitted for inspection, 296 were deep well water, with a fluorine content exceeding the standard of 18.9%, while the fluorine content of shallow wells in the village was normal. A total of 1 817 shallow wells had a fluorine content exceeding the standard of 0.9%. The fluorine content in deep well exceeded the standard of well water. Conclusion Due to the geological reasons, some deep-water water in rural Fuqing City is endangered by high fluorine, so it is suggested to take measures to change the water source.
