“…The submersed and free-floating species accumulated high levels of metals in both their roots and shoots. Metals accumulated in the shoots of E. canadensis and P. natans were derived mostly from direct metal uptake from the water column [31][32][33].…”

“…Previous studies demonstrate that acquatic plants can accumulate heavy metals relative to concentrations in the surrounding water (Miller et al 1983;Heisey & Damman 1982;Kovacs 1978;Dietz 1973) and nutrients from the sediments (Barko & Smart 1981;Carignan & Kalff 1980;Bristow & Whitcombe 1971) but these studies rarely involve more than a limited number of sites in a single geographical area so the generality of these patterns is unestablished. Because the costs of primary investigation are high, the analysis of published data from many locations offers an effective first step in the development of general models.…”

Abstract.A simple view of the role of rooted macrophytes in element cycling sees them as pumps retrieving buried elements from the sediment profile. To investigate the relationship between the elemental composition of plants and sediments, we analysed published data for 39 elements. The best general model explained 84% of the variance of the log of plant element concentration: This close relationship between the concentrations of an element in plant tissues and in the underlying sediment indicates that acquatic plants do not differ markedly in element composition from the sediments in which they grow. T-tests between mean residuals indicated that these aquatic plants do not discriminate between essential and nonessential elements. Model I1 regression analyses showed no difference between the slopes of the functional relationships for individual elements and that of the general model. When the elements were separated into three groups (alkali, transition and related metals, and halogens), Log Sediment Element accounted for 75-96% of the variation in LPE. Element physicochemical parameters were also significant independent variables explaining an additional 3-12% variation in LPE. The relative importance of the independent variables differed for the three groups of elements.Abbreviations: AN -Atomic number, AR -Atomic radius (nm), ELEC -Electronegativity, IPD -Ionization potential differential (eV: the difference in ionization potential between the used and next lower oxidation number), IR -Ionic radius (nm), LPE -Log plant element (ug/g dry wt.), LSE -Log sediment element (ug/g drt wt.), OP -Oxidation potential (eV), ORG -Sediment organic content (ug/g dry wt.)
