Evaluation of the potential of Pistia stratiotes L. (water lettuce) for bioindication and phytoremediation of aquatic environments contaminated with arsenic.
Specimens of Pistia stratiotes were subjected to five concentrations of arsenic (As) for seven days. Growth, As absorption, malondialdehyde (MDA) content, photosynthetic pigments, enzymatic activities, amino acids content and anatomical changes were assessed. Plant arsenic accumulation increased with increasing metalloid in the solution, while growth rate and photosynthetic pigment content decr...

متن کاملPhytofiltration of uranium by aquatic plants of Central Portugal
The strategies of metal tolerance developed by several plants that enable them to survive in metal contaminated and polluted sites. Some of them may accumulate significant concentration of a specific element. The work presented here is part of the on going study in Central Portugal, and it focus only in a preliminary description. We have observed that Apium nodiflorum, Callitriche stagnalis, Le...
متن کاملHeavy metals phytoremediation by aquatic plants (Hyrocotyle ranocloides, Ceratophyllum demersum) of Anzali lagoon
Wetlands are often considered sinks for contaminants, and Aquatic plants have been shown to play important roles in wetland biogeochemistry through their active and passive circulation of elements. In this research, in order to evaluate the concentration level of heavy metals released by the urban, industrial and agricultural activities at the margin of the rivers flowing into Anzali lagoon, as...
