“…accumulated greater concentrations of metals than shoots, indicating the bioavailability of metals and their limited mobility and translocation once inside the plant. This is consistent with many previous observations (Almeida et al 2011(Almeida et al , 2006Chandra et al 2008;Maddison et al 2005;Deng et al 2004;Mays and Edwards 2001;Sasmaz et al 2008). For example, the results from Sasmaz et al (2008) showed that the root tissues of Typha latifolia from a metal polluted stream were usually found to contain higher concentrations of most metals compared to the aboveground parts.…”

International audienceThe concentrations of heavy metals in water, sediments, soil, roots, and shoots of five aquatic macrophytes species (Oenanthe sp., Juncus sp., Typha sp., Callitriche sp.1, and Callitriche sp.2) collected from a detention pond receiving stormwater runoff coming from a highway were measured to ascertain whether plants organs are characterized by differential accumulations and to evaluate the potential of the plant species as bioindicators of heavy metal pollution in urban stormwater runoff. Heavy metals considered for water and sediment analysis were Cd, Cr, Cu, Ni, Pb, Zn, and As. Heavy metals considered for plant and soil analysis were Cd, Ni, and Zn. The metal concentrations in water, sediments, plants, and corresponding soil showed that the studied site is contaminated by heavy metals, probably due to the road traffic. Results also showed that plant roots had higher metal content than aboveground tissues. The floating plants displayed higher metal accumulation than the three other rooted plants. Heavy metal concentrations measured in the organs of the rooted plants increased when metal concentrations measured in the soil increased. The highest metal bioconcentration factors (BCF) were obtained for cadmium and nickel accumulation by Typha sp. (BCF = 1.3 and 0.8, respectively) and zinc accumulation by Juncus sp. (BCF = 4.8). Our results underline the potential use of such plant species for heavy metal biomonitoring in water, sediments, and soil

“…Various studies have pointed out that plants can favor the accumulation of metals in the sediment in contact with its roots through several mechanisms (Madureira et al, 1997;Almeida et al, 2006). Moreover, root activity is able to modify characteristics such as Eh, pH and microbial activity, which eventually modifies metal retention capacity (Williams et al, 1994;Almeida et al, 2004).…”

“…Vascular plants in salt marshes are crucial to the dynamics of the estuarine ecosystem and strongly influence processes of heavy metal accumulation (Alberts et al, 1990;Weis et al, 2002;Windham et al, 2003). Several studies have pointed out that plants can alter the chemistry of the sediment in contact with their roots (rhizosediment) (Madureira et al, 1997;Almeida et al, 2006). In this way, plant activity can influence metal mobility, depending on the existing physicochemical properties in the salt marsh sediment (Jacob & Otte, 2003).…”

The role of two Spartina species in phytostabilization and bioaccumulation of Co, Cr, and Ni in the Tinto–Odiel estuary (SW Spain)

Vascular plants in salt marshes strongly influence processes of heavy metal accumulation. Many studies have focused on this issue; however, there is a lack of information regarding the effects of plants on the distribution of certain poorly studied metals, such as Co, Cr, and Ni. The aim of this study was to comparatively evaluate the capability of Spartina densiflora Brongn. and Spartina maritima (Curtis) Fernald, to accumulate Co, Cr, and Ni and influence the sediment composition around their roots, investigating whether the observed behavior can change with different levels of sediment pollution. Concentrations of Co, Cr, and Ni were determined in tissues of S. densiflora and S. maritima and in sediments and rhizosediments from the Odiel and Tinto marshes (SW Spain), one of the estuaries most polluted by heavy metals in the world. Concentrations of Co, Cr, and Ni in the belowground tissues of both Spartina species were higher than those in aboveground tissues in all sites sampled. Both species showed potential for phytostabilization of Co, possibly by promoting the formation of high amounts of Fe-oxides in the rhizosphere, which can act to retain the metal within the sediment around the roots. In addition, both Spartina species were found to accumulate Co in their roots, thereby avoiding the translocation of this metal to photosynthetic tissues. At the Tinto marsh, there were no differences recorded in metal levels between sediments and rhizosediments of both species, a fact that could be explained by the extremely high background levels of metals at this site, which may impair the ability of the plant to alter the chemistry of the sediment in contact with the roots. The potential for the immobilization of a large amount of Co in the soil, exhibited by S. densiflora and S. maritima, indicates that both species could be highly useful in the phytostabilization of Co contaminated environments.

“…This has been documented for species such as Phragmites australis (Bragato et al 2006), Bolboschoenus maritimus (Almeida et al 2006;Bragato et al 2006;Madejón et al 2006a), and Spartina alterniflora ) that can accumulate and store metals in their roots.…”

“…maritimus is widely used in the reconstruction, creation and rehabilitation of wetlands (Kantrud 1996) and as test species in pollution-related studies in various countries around the world (Otte et al 1991;Clevering 1995;Almeida et al 2006;Madejón et al 2006a). However, no such studies have been done in South Africa, even though the plant is commonly found on riverbanks around the Cape Peninsula and northwards (Trinder-Smith 2003).…”

The Diep River is a major freshwater ecosystem in the Western Cape, South Africa. Although it is surrounded by many sources of metal pollution, the actual metal levels in this river system are unknown. Wetland plants are known to accumulate metals and may possibly be used as biomonitors of metal contamination in a river system. One such species, the sedge Bolboschoenus maritimus, is found in abundance along the banks of this river. The aim of this study was to investigate and monitor the degree of metal contamination in the water and sediments of the lower Diep River, as well as to study the seasonal accumulation and distribution of metals in B. maritimus, and the use thereof as biomonitor species. Two sampling sites were used: one site above the wetland section of the river, receiving runoff mainly from agricultural lands (site 1), and one site close to the river mouth (site 2), exposed to several possible pollution sources. Water, sediment, and plant (root, leaf and stem) samples were collected seasonally for 1 year and analyzed for Al, Zn, Cu, and Fe. There was greater bioaccumulation of metals by plants at site 2, due to greater bioavailability of metals. B. maritimus was shown to be a root accumulator of metals. Seasonal fluctuations in root, stem, and leaf metal concentrations did not follow seasonal sediment concentration patterns. However, using B. maritimus as test species did provide valuable additional information to sediment and water analyses. More extensive research is needed to conclude whether this species is an effective biomonitor in the lower Diep River environment.
