Uptake of Ag, Co and Ni by the Organs of <i>Typha domingensis</i> (Pers.) Poir. ex Steud. in Lake Burullus and Their Potential Use As Contamination Indicators

Abstract

The concentrations of Ag, Co and Ni in the sediments and the different organs of Typha domingensis from Lake Burullus, Egypt, were investigated monthly from February to September 2010 to evaluate the aquatic environment quality of the lake and to test the suitability of these organs for bio-indicating of sediment metals. The sediment heavy metals were found to decrease in the order of Ni > Co > Ag. The sediment contents of Ag were about 45 times above the worldwide range. On the other hand, Co concentrations were below the reference ranges of United States and Chinese soils. The heavy metals bioaccumulation decreased according to the order of rhizome > root > leaf for Ag; and root > rhizome > leaf for Co and Ni. It was found also that, T. domingensis had no significant differences in heavy metals concentrations over time. The transfer factors of Ag, Co and Ni from sediment to below-ground organs were smaller than one. Co had the maximum transport from below-ground to above-ground organs, while Ag had the minimum. There was a significant linear correlation between the concentration of Ag in root of T. domingensis and that in sediment. This result suggested that T. domingensis can be regarded as bio-indicator for Ag pollution of Lake Burullus.

Elements Accumulation and Nutritive Value of Phragmites Australis (Cav.) Trin. ex Steudel in Lake Burullus: A Ramsar site, Egypt

“…Although, there are a little data on the use of littoral plants as heavy metals bioaccumulators over large areas of the wetlands environment, these littoral plants are commonly used in constructing wetlands for accumulating large amounts of heavy metals (Peverly et al, 1995;Southichak et al, 2006;Liu et al, 2007;Vymazal et al, 2009;Drzewiecka et al, 2010 andEid et al, 2012).…”

Effects of Amendments on Growth and Uptake of Cd and Zn by Wetland Plants,Typha angustifoliaandColocasia esculentafrom Contaminated Sediments

“…Several wetland plant species (Typha latifolia, T. angustifolia, T. angustata, T. domingensis, Phragmites australis, Bacopa monnieri, Colocasia antiquorum) have been shown to accumulate and remove heavy metals (Raiet al 1995;Ye et al 2001;Batty, 2003;Panich-Pat et al 2004;Bose et al 2008;Dixit and Tiwari 2008;Eid, El-Sheikh, and Alatar 2012;Kashem et al 2013). In order to find suitable plants for phytoremediation of heavy metals, they have to be tested for their tolerance to metals, their ability to extract or stabilize metals, and their growth rates.…”

Seasonal allocation of carbohydrates between above‐ and below‐ground organs of Typha domingensis

“…In Egypt, it spreads in water bodies such as lakes, ditches and marshy places (Täckholm , Boulos ;); and it is one of the major components of the vegetation stands along the shores of Lake Burullus close to the Deltaic Mediterranean coast (Shaltout and Al‐Sodany ). Although T. domingensis is now attracting attention for their usefulness in various ecological fields such as the influence on greenhouse gas emissions from wetlands (Chanton et al ), mitigation strategies (Dobberteen and Nickerson ), wetlands diversity restoration (Newman et al ) and purification of polluted water (Hegazy et al ; Eid et al ), it is sometimes considered an invasive weed (Newman et al. ), where the overgrowth of this species that dominates aquatic habitats is often viewed as a potential threat to shallow ecosystems; and therefore, control of dramatic expansion of this aquatic plant has attained attention (Marks et al ).…”

“…Many studies were carried out on T. domingensis such as nutrients and heavy metals cycling (Eid et al ), phytoremediation (Hegazy et al ), productivity (Eid et al ), modeling the growth dynamics (Eid et al. ), flooding stress (Chen et al ), restoration (Newman et al ), and distribution (Khedr , Khedr and El‐Demerdash ).…”
