1、松嫩平原地下水氟、砷的富集规律及影响因素研【摘要】本论文依托中国地质调查局东北地方病严重区地下水勘查及供水安全示范工程和吉林省地调局吉林省西部高氟、高砷区生态环境地球化学评价项目。松嫩平原地下水原生水质不佳,是我国地方性氟、砷中毒病区。长期以来由于水质问题导致该区地下水资源紧缺,严重制约了社会经济的发展。因此,为保证区域饮水安全,合理开发利用地下水资源,开展地下水中氟、砷中毒的研究十分必要。在资料收集、野外调查、样品采集及测试分析的基础上,应用水文地质学、水文地球化学的基本理论和方法,借助野外调查、测试分析及数据分析技
2、术等,结合地质、地貌特点,开展了松嫩平原地下水氟、砷的分布特征及相关的水化学特征研究。在查阅大量国内外文献的基础上,结合项目组实测数据及对比国内氟、砷中毒地区,分析了研究区地下水氟、砷的,归纳总结了影响两者富集的因素,提出了典型区地下水氟、砷的富集特征进行了分析,建立了富集影响因素评价指标体系。在区域宏观分析的基础上,选取典型地区进行地下水中氟、砷富集特征及影响因素的总结。【Abstract】SongnenPlainisrichingroundofentionedproblemsofand.Therefore,fort
