| 1 | Phytoremediation potential of charophytes:Bioaccumulation and toxicity studies of cadmium,lead and zinc显示文摘The ability for usage of common freshwater charophytes,Chara aculeolata and Nitella opaca in removal of cadmium (Cd),lead (Pb) and zinc (Zn) from wastewater was examined.C.aculeolata and N.opaca were exposed to various concentrations of Cd (0.25 and 0.5 mg/L),Pb (5 and 10 mg/L) and Zn (5 and 10 mg/L) solutions under hydroponic conditions for 6 days.C.aculeolata was more tolerant of Cd and Pb than N.opaca.The relative growth rate of N.opaca was drastically reduced at high concentrations of Cd and Pb although both were tolerant of Zn.Both macroalgae showed a reduction in chloroplast,chlorophyll and carotenoid content after Cd and Pb exposure,while Zn exposure had little effects.The bioaccumulation of both Cd and Pb was higher in N.opaca (1544.3 μg/g at 0.5 mg/L Cd,21657.0 μg/g at 10 mg/L Pb) whereas higher Zn accumulation was observed in C.aculeolata (6703.5 μg/g at 10 mg/L Zn).In addition,high bioconcentration factor values (> 1000) for Cd and Pb were observed in both species.C.aculeolata showed higher percentage of Cd and Pb removal (> 95%) than N.opaca and seemed to be a better choice for Cd and Pb removal from wastewater due to its tolerance to these metals. | Najjapak Sooksawat Metha Meetam Maleeya Kruatrachue Prayad Pokethitiyook Koravisd Nathalang | 2013 | Journal of Environmental Sciences2013，25，3： | 5 |
| 2 | Alterations of organ histopathology and metallolhionein mRNA expression in silver barb,Puntius gonionotus during subchronic cadmium exposure显示文摘普通的银倒刺, Puntius gonionotus,为 60 d 暴露了到 0.06 mg/L Cd 的名字的集中,为组织病理学说的改变(鳃,肝和肾) 被估计,金属累积,和 metallothionein (MT )信使 rna 表示。鱼展出了象主要、第二等的鳃 lamellae 的肥大和增生那样的病理学的症状,在 hepatocytes 的 vacuolization,并且突出管状并且在肾的 glomerular 损坏。另外,肾积累了镉的最高的内容,多于鳃和肝。MT 信使 rna 的表示在对待的鱼的肝和肾被增加。在鱼被移开到 Cd 免费的水以后,肝的 MT 层次仍然保持高。相反,在肾的 MT 表示在处理的 28 d 以后被达到顶点并且当鱼被移开到 Cd 免费的水时,急速地落下。在肝的纸巾的 Cd 的高集中在这纸巾上显示了一个累积地点或永久损坏。 | Alisa Wangsongsak Suwimol Utampongsa Maleeya Kruatrachue Mathurose Ponglikitmongkol Prayad Pokethitiyook Thitinun Sumranwanich | 2007 | Journal of Environmental Sciences2007，19，11： | 1 |
