摘 要: | 目的探讨杞县农村饮水型地方性氟中毒病区分散式供水水氟、水砷含量与井深的关系,寻找适宜氟砷含量的饮水层,为地方病防治提供基础资料和科学依据。方法采集杞县氟中毒病区饮用井水样,测定水中氟、砷的浓度,分析浓度分布特点以及水氟、水砷、水井深度三者之间的关系。结果杞县地方性氟中毒病区水井深度在66 m以内,水氟含量与饮水井深度之间呈正相关关系,相关系数为0.108。水砷浓度与饮水井深度呈负相关关系,相关系数为-0.170。水氟含量与水砷含量之间无相关关系。结论饮水型地方性氟中毒病区水氟、水砷含量与井深之间有密切关系。水氟含量随饮水井深度的增加而增高;水砷含量随饮水井深度的增加而降低;而水氟、水砷浓度间不具有相关性。杞县饮水型地方性氟中毒病区饮水应避开现用水层,选择地表水或深层地下水。

Abstract: | objective To explore the relationship between the concentration of water fluoride , water arsenic and the depth of drinking well in the endemic fluorosis areas of Qixian , in order to provide the basic information and the scientific evidence. Methods We have collected water samples of drinking well, determined the concentration of fluorine and arsenic, analysed the distribution characteristics of concentration and the relationship between the concentration of water fluoride ,water arsenic and the depth of drinking well. Results The concentration of fluorine and the depth of drinking well have positive correlation, the correlation coefficient is 0. 108. The concentration of arsenic and the depth of drinking well have negative correlation, the correlation coefficient is -0.170. The concentration of fluoride and the concentration of arsenic have no correlation . Conclusion There are close relationship between the concentration of fluorine, the concentration of arsenic and the depth of drinking well. Water fluorine concentration rises along with the depth of drinking well increase, water arsenic concentration descends along with the depth of drinking well increase. But the concentration of fluoride and the concentration of arsenic have no correlation. The water renovation in the water - drinking endemic fluorosis oreas of Qixian should avoid the current water layer,chose the surface water or the deep groundwater. |
