“…It was found that the R/L and R/S ratios for Cr in MM were mostly greater than 1, indicating that the mobility of Cr from the roots to shoots or leaves was very weak. Similar results were drawn by Baldantioni et al (2004). The reason for the low mobility of Cr from roots to shoots might be due to the metabolism of the element (Shewry and Peterson 1974).…”

To understand the temporal variations and bioaccumulation of heavy metals in the coastal marshes, the concentrations of heavy metals (Cr, Ni, Pb, and Cu) in the two Suaeda salsa marshes [middle S. salsa marsh (MM) and low S. salsa marsh (LM)] of the Yellow River estuary were determined from May to November in 2008 by in situ sampling and inductively coupled plasma mass spectrometry (ICP-MS) analysis. Results showed that heavy metal concentrations in S. salsa of MM and LM were generally in the order of Cu>Cr>Pb>Ni, while those in sediments fell in the order of Cr>Ni>Cu>Pb. Heavy metal concentrations of S. salsa in MM and LM were different, and significant differences were observed in stems (F = 4.797, p= 0.046) and litters (F=6.799, p=0.026) for Ni. Litter was the main stock of heavy metals, and the allocations of Cr, Ni, and Pb reached 31. .64 % (in LM), respectively. The ratios of roots/ leaves (R/L) and roots/stems (R/S) for Cr and Ni in MM were mostly greater than 1, while those ratios in LM were mostly less than 1, indicating that Cr and Ni in S. salsa at LM had greater mobility compared with those at MM. Moreover, the [accumulation factor, AF] plant of Cr, Ni, Cu, and Pb in LM, especially [AF] root and [AF] stem of Cr and [AF] litter of Ni, was also higher than that in MM. These indicated that S. salsa grown in LM was more suitable for potential biomonitor or phytoremediation of Cr, Ni, Cu, and Pb if intertidal sediments were seriously contaminated with an increase of pollutant loading (especially heavy metals) in the Yellow River estuary. The use of biomonitor (S. salsa) living and growing in LM could yield valuable information not only on the presence of anthropogenic stressors, but, more importantly, on the adverse influence the stressors are having on the environment.

“…The stems of the plants showed considerably higher chromium, cadmium and lead (5.34, 0.04, 3.05 mg kg -1 respectively) than the results obtained from the stem in this study. Baldantoni et al (2011) analyzed the distribution of chromium in two aquatic plants (Phragmites communis and Najas marina). They found higher chromium concentrations in the roots than in the green parts of the plant, as in this study.…”

“…Reeds can withstand extreme environmental conditions, including the presence of toxic contaminants such as heavy metals (Ye et al, 1997;Baldantoni et al, 2004;Quan, 2007;Bonanno & Lo Giudice, 2010). There are many cases in which, as other wetland plants, reed is utilized for the removal of pollutants, including metals (Chiu et al, 2006;Calheiros et al, 2009).…”

Common reeds (Phragmites australis) as sustainable energy source: experimental and modelling analysis of torrefaction and pyrolysis processes

et al. 2012

The aim of this study is to apply advanced analytical techniques and kinetic modelling to common reeds (Phragmites australis) to characterize its pyrolysis and torrefaction as possible environmental friendly and sustainable pathways of fuel upgrading. Simultaneous thermogravimetric and differential scanning calorimetry analysis have been carried out on common reeds. The evolved gases during the decomposition process have been analysed by a coupled infrared gas analyser and gas chromatograph/mass spectrometer. Different reed origins (China and Italy) and plant parts (stem and leaves) have been compared. The results have been used to calibrate a torrefaction kinetic model. The model has also been tested simulating a reed torrefaction run occurring in a bench-scale apparatus, supplementing the chemical analysis with a thermal simulation of the reactor carried out through a finite elements approach. The results show that the proposed modelling approach allows the prediction of the reaction products with a satisfying degree of accuracy. Besides its phytodepuration potential, P. australis has proven to be an interesting natural biomass resource for thermochemical conversion processes and energy production both for its suitability and availability.
