I did not make a study on cadmium hyperaccumulation of Nelumbo nucifera. However in my opinion you may study on this hyperaccumulator plants

Ben,

  there is a similar discussion about phytoremediation in the other thread. Yes, there is some information about lotus in the book that we had published - but not for cadmium, per se.

We had other papers about Cd and the interaction with legumes.

Article Legumes Can Increase Cadmium Contamination in Neighboring Crops

Nelumbo nucifera was studied for phytoremediation of heavy metals and other contaminants. The following articles might be useful for your reference.

Hi Ben,

It is not clear to me either why so much has been published on the phytoremediation potential of Nelumbo nucifera and so less on that of N. lutea. On p. 85 of Orozco-Obando’s thesis, referred to by Srujana Kathi, the author writes "These results are in agreement with other studies of Cu removal using wild species of lotus (N. lutea).“ You might contact the author directly for more information on this. I also found this reference to a submitted publication co-authored by him:

Orozco-Obando, W., K. Tilt, D. Eckman, B. Dudderar, F. Dane, J. Sibley, F. Woods, W. Foshee, J. Chappell, D. Cline, and F. Woods. 2008b. Determination of phyto-remediation potential of Sacred Lotus (Nelumbo nucifera) and Native American Lotus (Nelumbo lutea) in Constructed Wetlands. Proc. 22nd Chinese Lotus Conference. Beijing, China. 6 pages (submitted).

There is also a reference to the accumulation of Pb in the fruits of N. lutea in Table 1 on p. 242 of:

Behan, M. J., Kinraide, T. B., & Selser, W. I. (2013). Lead Accumulation in Aquatic Plants. from Metallic Sources Including Shot. The Journal of Wildlife Management 43(1), 240–244.

On the accumulation of TCS (Triclosan) in the roots of N. lutea, see http://goo.gl/rWTX63 =

Adhikar S. 2010. Solvent effects and bioconcentration patterns of antimibrobial

compounds in wetland plants [thesis]. [Denton (TX)]: University of North Texas,

which is referred to in http://goo.gl/NBmK7s, p. 44.

Regarding the difference between nucifera and lutea I follow the classification proposed in

Th. Borsch, W. Barthlott 1994. Classification and Distribution of the Genus Nelumbo

Adans. (Nelumbonaceae). Beiträge zur Biologie der Pflanzen 68, 421-450.

On p. 440 the authors argue that the genus "Nelumbo comprises only one species with two geographically separated subspecies." They arrived at this conclusion since “[t]here are no significant differences in the vegetative morphology of the Old and New World plants, and there are also no differences in anatomy. [...] N. lutea and N. nucifera only differ in a few weak characters in the flower as perianth colour and morphology of stamen appendages” (ibid.: 439f.).“

So it is probably not unlikely that the phytoremediation faculties of Nelumbo nucifera subsp. nucifera are present in N. nucifera subsp. lutea as well.

Best,

Thomas

I didn’t find many research articles on Nelumbo lutea (American Lotus) in the context of metal phytoextraction. The following references may be helpful for your research.

Abstract: Although the use of wetland ecosystems to purify water has gained increased attention only recently, it has been recognized as a wastewater purification technique for centuries. While considerable research has occurred to quantify the nutrient (nitrogen and phosphorus) removal mechanisms of wetlands, relatively few investigators have focused on the mechanisms of heavy metal removal and uptake by wetland sediments and plants. The quantification of the assimilative capacity of heavy metals by wetland ecosystems is a critical component in the design and use of wetlands for this purpose.

A computer model has been developed to simulate the fate and transport of heavy metals introduced to a wetland ecosystem. Modeled water quality variables include plankton biomass and productivity; macrophyte (Nulumbo lutea) biomass; total phosphorus in the water column; dissolved copper in the water column and sediments; particulate copper in the water column and sediments; and suspended solids. These variables directly affect the modeled rate of copper uptake by macrophytes, and the rate of copper recycling as a function of the decomposition of copper-laden biomass litter.

In addition, the following references on Nelumbo nucifera (Indian Lotus) may be useful to design your research.

Abstract: A study was conducted to assess the ability of N. nucifera Gaertn. in chromium removal and in bioassay using a few modifiable physiological responses. Plants grown in different chromium concentrations (50 to 200 μM) showed appreciable amounts of the same accumulated in their tissues, maximum being in roots. Higher amounts of chromium accumulated in plant tissues result significant inhibition in chlorophyll, protein contents and in vitro nitrate reductase activity in test plant. A concentration - duration dependent response induced by chromium was also recorded. Sensitivity of nitrate reductase activity in the presence of both nitrate and ammonical nitrogen could be used as a bioassay index for toxicity assessment against supraoptimal concentrations of chromium.
