摘　　要：综述了国内外对水体中氟的存在形态、植物对水体氟污染的去除效果、水体氟对植物的生态毒理效应、影响水体氟植物修复的因素,并提出了今后宜进一步加强研究方向。天然水中氟的存在形态主要以F-、未离解的HF以及与铝、铁和硼形成络合物存在;不同植物或同一植物的不同组织对水体氟吸收、蓄积能力有明显的区别;水体氟对植物的生态毒理效应主要表现在对植物的形态和生长、光合作用和代谢方面的影响;影响水体氟植物修复的因素有植物本身和水体环境两方面;植物吸收、蓄积水体氟的具体生物化学机制仍有待深入研究。The forms of fluorine existed in water,the effect of removing fluorine by plants,the eco-toxicological effect to water fluoride and the factors which influence the water fluorine by phytoremediation were reviewed,and the further research direction was also pointed out.The forms of fluorine existed in natural water mainly contained F-,HF which didn＇t dissociated,and comoles compounds formed with Al,Fe and B.There were evident difference of the ability among different tissues in different plants or one plant that can absorpt and accumulate the fluorine in water.The eco-toxicological effect to fluoride in water were mainly manifested in the influence of morphous,growth,photosynthesis and metabolism in plants.the water conditions and plants itself can influence the phyto-remediation from water.The biochemical mechanism of absorption and enrichment of fluoride in water by plants need to be further studied.
