The immediate effect of zinc (Zn) and hydrogen peroxide (H2O2) in Chara braunii was analyzed in short‐time exposure experiments. The exposure concentrations were 12.3, 18.4, and 24.5 μmol L−1 H2O2, 12, 60, and 120 mg L−1 Zn, and 12.3 μmol L−1 H2O2 + 12 mg L−1 Zn, 12.3 μmol L−1 H2O2 + 60 mg L−1 Zn, and 18.4 μmol L−1 H2O2 + 12 mg L−1 Zn. The stress response of C. braunii was analyzed by measuring photosynthetic...
The present study was carried out in natural stands of Typha domingensis in Lake Burullus, Egypt, to investigate (1) nutrient dynamics and heavy metals accumulation in its organs, (2) the phytoextractive potential of its organs and (3) the amount of nutrients and heavy metals released back into the water after decomposition of the dead tissues. Nitrogen concentrations were higher in the shoot than...
