Studies were conducted on the bioconcentration of fluoride (F(-)) in five submerged plants species. Ceratophyllum demersum, Hydrilla verticillata, Potamogeton malaianus, Myriophyllum verticillatum and Elodea nuttallii were all able to remove F(-) from water to some degree of efficiencies. At 5-20 mg F(-)/L culture solution, C. demersum had the best F(-)-removal performance, E. nuttallii had the poorest F(-)-removal performance among these plants. The relative growth rate (RGR) of the five species varied in different concentrations of F(-), of which C. demersum had the highest RGR. Its RGR decreased by 26.3 %, 63.2 % and 73.7 % from controls at 5, 10 and 20 mg F/L, respectively.
研究了五种沉水植物对氟（F（-））的生物浓缩作用。金鱼藻、黑藻、穗状狐尾藻、竹叶眼子菜和水花生都能在一定程度上从水中去除 F（-）。在 5-20 mg F（-）/L 培养液中，金鱼藻对 F（-）的去除效果最好，而水花生在这些植物中的去除效果最差。五种植物的相对生长率（RGR）在不同浓度的 F（-）中有所不同，其中金鱼藻的 RGR 最高。其 RGR 在 5、10 和 20 mg F/L 时分别比对照下降了 26.3%、63.2%和 73.7%。
