concentrations to environmentally acceptable levels, and be applicable to field conditions such as effluents and aquatic bodies. Currently, phytoremediation of metals is an effective and affordable "green" technology based on the use of specially selected metal accumulating plants to remove toxic metals from soils and water. This environment friendly technology has aesthetic advantages and long-term applicability. It is a rapidly developing method that uses plants to reduce, degrade, assimilate and metabolize environmental pollutants such as heavy metals, hydrocarbons, pesticides, etc. Phytoremediation techniques do not require specialized equipment and are accepted by local communities. Plants with exceptional metal-accumulating capacity are known as hyperaccumulator plants. Phytoremediation utilizes the unique and selective uptake capabilities of plant root systems, together with the translocation, bioaccumulation, and contaminant degradation abilities of the entire plant …
1. Introduction Iron plaque (IP) formation occurs commonly on the surface of roots of aquatic and wetland plants. It is either amorphous or crystalline in structure, containing iron (Fe) hydroxides, goethite, and lepidocrocite. 1–3 Many studies show that IP contains Fe hydroxides of a mixed-phase; often crystalline and poorly-crystalline phases are in close proximity on aquatic roots.

Three aquatic plants were examined for their ability to remove heavy metals from contaminated water: parrot feather (Myriophylhum aquaticum), creeping primrose (Ludwigina palustris), and water mint (Mentha aquatic). The plants were obtained from a Solar Aquatic System treating municipal wastewater. All the three plants were able to remove Fe, Zn, Cu, and Hg from the contaminated …
Heavy metals are toxic to soil, plants, aquatic life and human health if their concentration is high in the compost. Heavy metals exhibit toxic effects towards soil biota by affecting key microbial processes and decrease the number and activity of soil heavy metals ...
The studies involved samples of aquatic plants collected from 15 sites (Fig. 2) locat-ed along the shoreline of the reservoirs. The mean concentrations of heavy metals (Mn, Fe, Cu, Zn, Cd and Pb) determined in the biota samples are shown in Tables 3 and 4.

Phytoremediation of heavy metals with cucumber, white poplar and aquatic plants SUMMARY Scientific advisors: Prof. Dr. Luminița Silaghi Dumitrescu …
Ratios of metals in stem versus leaves in all plants ranged from 0.2 to 25.8, indicating various accumulation capabilities of plant organs. These findings contribute to the application of submerged aquatic plants to heavy metal removal from moderately
Due to specific morphology and higher growth rate, free-floating plants were more efficient to uptake heavy metals in comparison with submerged and emergent plants. In this review, the potential of wide range of aquatic plant species with main focus on four well known species (hyper-accumulators): Pistia stratiotes, Eicchornia spp., Lemna spp. and Salvinia spp. was investigated.
