“…During the active period of growth, the metal concentrations in plant parts decline and during the senescence metal concentrations build up again. Some researchers refer this phenomenon as a strategy of heavy metal tolerance (Dahmani-Müller et al, 2000;Brekken and Steinnes, 2004;Weis et al, 2004). …”

Heavy metal bioaccumulation and translocation properties of aquatic plants are interesting because of their potential use in phytoextraction. However, there is not enough knowledge about the seasonal changes of the metal distribution properties of aquatic plants. Our study focused on seasonal variation of some heavy metals in relation to their bioaccumulation and translocation in Nuphar lutea, a floating leaved, widespread plant that is important to wildlife. In this study, N. lutea, corresponding sediment and water samples were collected at different seasons from Lake Abant (Turkey) and analysed for their heavy metal content (Pb, Cr, Cu, Mn, Ni, Zn and Cd). Accumulation and translocation of heavy metal ratios were calculated seasonally. It was found that Cr and Zn were actively transported from sediment to the root, where they accumulated especially in summer; it was also shown that Cu, Mn and Zn were not only taken up from the sediment but also from the surrounding water. The investigations suggested that translocation ratios for leafyroot of Pb, Cr, Mn and Zn reached their highest levels in spring. It was found that the bioaccumulation and translocation of heavy metals at different parts of N. lutea changes with respect to season and the type of heavy metal.

“…Nevertheless, there is the likelihood of elevated levels in the root parts, as reported elsewhere (Deng and Wong, 2004;Vesk and Allaway, 1997). Most plants, save those that can hyperaccumulate metals (Thangavel and Subbhuraam, 2004), restrict the metal mobility to the photosynthetic (Weis et al, 2004) and other active tissues.

“…Zn accumulation in roots was two times higher compared to aerial parts in the case of T. angustifolia and E. arundinaceus (Table 5). Earlier studies had also reported that many wetland plants are mainly root accumulators for Zn (Stoltz and Greger 2002;Weis et al 2004).…”

The paper production is material intensive and generates enormous quantity of wastewater containing organic pollutants and heavy metals. Present study demonstrates the feasibility of constructed wetlands (CWs) to treat the heavy metals from pulp and paper industry effluent by using vertical flow constructed wetlands planted with commonly available macrophytes such as Typha angustifolia, Erianthus arundinaceus, and Phragmites australis. Results indicate that the removal efficiencies of the planted CWs for iron, copper, manganese, zinc, nickel, and cadmium were 74, 80, 60, 70, 71, and 70 %, respectively. On the other hand, the removal efficiency of the unplanted system was significantly lower ranging between 31 and 55 %. Among the macrophytes, T. angustifolia and E. arundinaceus exhibited comparatively higher bioconcentration factor (10(2) to 10(3)) than P. australis.
