Long-term natural geochemical processes result in wide occurrence of fluoride contamination in underground water and fluoride exposure via drinking water for over 500 million people glo-bally. The control of fluoride pollution and fluorosis is one of the most important issues for drinking water safety. In the past several decades, many initiatives failed in defluoridation of water. Better understanding of fluoride occurrence mechanisms in underground water chemistry and the prediction of high-risk areas by geographic information and remote sensing are of crucial importance to minimize fluorosis occurrence. The use of alternative source water or blending should be considered as priority option. Much efforts should be devoted to the fundamental studies on defluoridation reagents and innovative materials, and to the development of highly-efficient, economic, easy-to-handle and stable technologies and integrated instruments. Furthermore, the design, construction, operation, and supervision of defluoridation facilities should be carefully evaluated and strengthened to achieve stable benefits as much as possible.
长期的自然地球化学过程导致地下水中氟化物污染广泛存在，全球超过5亿人通过饮用水接触氟化物。控制氟污染和氟中毒是饮用水安全的最重要问题之一。在过去几十年中，许多水脱氟举措都失败了。更好地了解地下水中氟化物的存在机制，以及利用地理信息和遥感技术预测高风险地区，对于尽量减少氟中毒的发生至关重要。应优先考虑使用替代水源或进行混合。应大力开展关于脱氟试剂和创新材料的基础研究，开发高效、经济、易于操作且稳定的技术和集成仪器。此外，应仔细评估并加强脱氟设施的设计、建设、运营和监管，以尽可能实现稳定的效益。
