The heavy metal cadmium (Cd) is highly toxic to plants. To understand the mechanisms of tolerance and resistance to Cd, we treated the rootless, submerged macrophyte Ceratophyllum demersum L. with sub-micromolar concentrations of Cd under environmentally relevant conditions. X-ray fluorescence measurements revealed changing distribution patterns of Cd and Zn at non-toxic (0.2 nM, 2 nM), moderat...

The epiphytic algae were studied on three aquatic plants (Ceratophyllum demersum, Myriophyllum verticillatum and Potamogeton pectinatus) from seven stations in Euphrates River between Hindia barrage Al-Kufa city-Iraq, during summer 2004 spring 2005. A total of (97) species identified, diatoms dominant their number (73% the number), followed by chlorophyta, then cyanophyta Euglenophyta. Variatio...

In the present study, cadmium (Cd) accumulation capabilities of aquatic macrophytes Ceratophyllum demersum, Bacopa monnieri and Rotala rotundifolia were determined after treating both individual and triple macrophytes. The macrophytes were treated with Cd at 0, 0.1, 1 and 10 mg/L concentrations in a controlled chamber for 12-days. Cadmium accumulations increased with increasing Cd concentratio...

This study evaluated the ability of submerged aquatic plant Ceratophyllum demersum to remove Acid Blue 92 (AB92) dye. The effect some operational parameters such as reaction time, initial dye concentration, biomass, and pH, on removal efficiency was studied. Based Taguchi’s results, optimized conditions for were time 7 days, concentration 20 mg l-1, biomass 4 g, pH 5. Fourier-transform infrared...
