“…Chemical transformation of bound phosphate to orthophosphate (AP) by microorganisms and enzymes secreted by plant roots results in higher removal efficiency for TP. Percent removal of P has been reported in the similar range (24.1-61.55) in another study on nutrient removal from wastewater by 15 wetland species including Canna (Jiang et al 2011). In the present study, average removal rate of TP (167 mg/m 2 day) was higher than that of AP (84 mg/m 2 day) as against the loading rate of 200 mg/m 2 day for TP and 85 mg/m 2 day for AP.…”

“…The study reported 40% more accumulation of P in shoots than roots at an influent level of 6.77 mg/L phosphate. In a similar study (Jiang et al 2011), 15 wetland plants were observed to accumulate higher concentration of phosphate in shoots than roots with maximum accumulation by Canna among the plants. If relative fraction of initial and final phosphorus in different tissues is compared, flowers accumulated relatively more concentration, and it would result in recirculation of phosphate in the form of organic phosphate (OP) with the fall of flowers into the wetland system.…”

Introduction: Considering the problem of eutrophication of the water bodies, phosphate removal from water has emerged as a research of topical interest. The present study aims to investigate the efficacy of Canna lily-based constructed wetland to remove phosphate from wastewater. The translocation of phosphate in plant tissue and its biochemical transformation in sediments is also studied to understand its accumulation and recirculation within the system. Results: The removal of phosphate stabilized at around 50% in the present study and plant uptake was found to be the major removal mechanism. Average removal was 167 mg/m 2 day for total phosphate and 84 mg/m 2 day for available phosphate for an initial loading rate of 200 mg/m 2 day and 85 mg/m 2 day, respectively, at a HRT of 24 h. Most of the phosphate concentrated in above ground tissue of plant and its relative accumulation was maximum in flowers. Fractionation of phosphate in sediments confirmed removal by sediments with an accumulation of apatite phosphate (Ca and Mg bound), but release of non-apatite form (Fe and Al bound). Conclusion:The study concludes that Canna-based constructed wetland can be an effective tool for phosphate removal from wastewater and sediments particularly under tropical conditions. Regular harvesting of above ground tissue of Canna can result in nutrient export from the system, whereas autochthonous addition may result in recirculation.

“…17,32,33 Plants Pc and Ao which could accumulate nitrogen and phosphorus in biomass have also been used for water restoration. 26,27 Moreover, the long fibrous roots with aerenchyma, which are conducive to increasing the root porosity, oxygen transfer, and photosynthetic rate, allow Pc to grow well in wastewater. 27 Thus, on the basis of the results of this hydroponic study, plants Pa, Ao, and Pc would be good candidates for further testing in a real-life system.…”

Uptake and Translocation of Perfluorooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) by Wetland Plants: Tissue- and Cell-Level Distribution Visualization with Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) and Transmission Electron Microscopy Equipped with Energy-Dispersive Spectroscopy (TEM-EDS)

Perfluoroalkyl substances (PFASs) are persistent chemicals in the environment. So far, little is known about their uptake potential in wetland plants.Here, we investigated the uptake and translocation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in eight common wetland plants, namely, Canna indica (Ci), Thalia dealbata (Td), Cyperus alternifolius (Ca), Phragmites australis (Pa), Arundo donax (Ad), Pontederia cordata (Pc), Cyperus papyrus (Cp), and Alisma orientale (Ao) by hydroponic experiments and visualized their tissue-and cell-level distribution with desorption electrospray ionization mass spectrometry (DESI-MS) and transmission electron microscopy equipped with energy-dispersive spectroscopy (TEM-EDS). The results showed that the PFASs accumulated in plants accounted for 1.67−16.7% of the total mass spiked into the hydroponic systems, and PFOS accumulated largely in roots (48.8−95.8%), while PFOA was stored mostly in the aboveground part (29.3−77.4%). DESI-MS and TEM-EDS analysis showed that PFASs in Ci, Td, Pa, and Ca were transported from the hydroponic solution to the root cortex via both apoplastic (e.g., across cell walls and/or intercellular spaces) and symplastic routes (e.g., across plasma membranes or via plasmodesmata) and further to the vascular bundle via symplastic route in Td and Pa and via both routes in Ci and Ca. These two chemicals were transported from roots to stems mainly through the cortex in Td and through both the cortex and vascular bundles in Ci and Ca.

“…Generally, there are correlations between vegetation biomass density and N and P uptake and biomass can be used as a surrogate for nutrient removal potential [49,50]. To validate the accuracy of the RIPAM model, we converted the biomass density to N and P uptake by using a simple ratio coefficient.…”

It should be noted that the Xrate is varied with elevation and water level.…”

Inter-basin water transfer projects are designed to relieve water scarcity around the world. However, ecological problems relating to reductions in protection zone functions can occur during inter-basin transfers. This paper uses the largest inter-basin water transfer project in the world, namely, the South-to-North Water Transfer Project (SNWTP) in China, as an example to analyze the variation of Miyun Reservoir's inner protection zone functions when water is transferred. Specifically, a riparian model (RIPAM) coupled with remote sensing data were used to calculate the nitrogen (N) and phosphorus (P) losses due to plant uptake, and these results were validated by in situ survey data. Then, correlations between water levels and N and P removal were analyzed. The results show that water table disturbances resulting from elevated water levels strongly influence the growth of plants and have obvious negative impacts on N and P removal in the inner protection zone. With the implementation of the middle route of the SNWTP, the water level of Miyun will rise to 150 m in 2020, and subsequently, the total net primary productivity (NPP) could decline by more than 40.90% from the level in 2015, while the N and P uptake could decline by more than 53.03% and 43.49%, respectively, from the levels in 2015, according to the modeling results. This will lead to declines in the inner protection zone's defense effectiveness for N and P interception and increases in risks to the security of water resources. The results of this study provide useful knowledge for managing the defense function of the terminal reservoir's inner protection zone and for ensuring that water quality is maintained during the diversion process.
