Biological accumulation of nickel and concomitant ecophysiological responses were studied in the leaves of Elodea canadensis treated with different concentrations of Ni (1-50 microM) for 5d. In low concentrations nickel was accumulated mainly in the soluble protein fraction, which correlated with
OBJECTIVE
Plants can absorb a diversity of natural and man-made toxic compounds for which they have developed diverse detoxification mechanisms. Plants are able to metabolize and detoxify a wide array of xenobiotics by oxidation, sugar conjugation, glutathione conjugation, and more complex
Elodea canadensis (Canadian waterweed) has an ability to accumulate and bioconcentrate heavy metals. In this work, selected cellular responses for Cu treatment were studied in leaves of E. canadensis. Short term experiments, i.e. 1 week exposure to 0.5, 1, 5, and 10 microM of Cu indicated that
Effects of Pb accumulation on the contents of chlorophylls (a and b), carotenoid, ascorbic acid (AsA), non-protein SH groups and protein were investigated in aquatic macrophyte Elodea canadensis. Pb accumulation in E. canadensis tissues increased with increasing metal concentrations. The increases
Elodea canadensis is an aquatic macrophyte used widely as a bioindicator for the monitoring of water quality and in the phytoremediation of metal-contaminated waters. This study considers the kinetics of nickel bioaccumulation and changes in accompanying metabolic and stress-related physiological
Dietary transfer of mercury (Hg) is central for its effects on higher trophic animals, nonetheless, its driving parameters and characteristics are not well understood. Here we measured Hg species transfer (uptake) from the macrophyte Elodea nuttallii -mimicking tissues incorporation in sediments
