Phytoextraction potential of Cynara cardunculus L. grown under single and binary cadmium and nickel treatment conditions
A greenhouse experiment was carried out using three groups of 12 pots each, filled with surface soil spiked by single and binary cadmium and nickel aqueous solutions. Measured bioavailable metal concentrations in soil ranged widely and were up to 246.7 mg kg-1 for Cd and 61.1 mg kg-1 for Ni.
Under CdTREATMENT cardoon growth remained unaffected, while elevated Ni soil concentrations led to severe reduction of plant growth. In Cd-NiTREATMENT an antagonistic effect was observed among the two metals. The amounts of Cd and Ni accumulated in cardoon plants were elevated and increased with increasing metal concentrations in the soil; higher concentrations of both metals were observed in the above-ground biomass and the Translocation Factor was higher than 1. A possible enhancing effect of nickel on cadmium uptake was observed. Cardoon showed to have characteristics only of a Cd accumulator, but further investigation under field conditions is needed.

A combined landfarming-phytoremediation system for remediation of petroleum hydrocarbons and metals from contaminated soils
© Aristotle University of Thessaloniki (6/2009)
Petroleum hydrocarbons are among the most common groups of persistent organic contaminants in the environment and are known to be toxic to many organisms. In this study, plant establishment and growth in two petroleum contaminated soils (S1 and S2), which were previously treated using landfarming technique, was evaluated. Investigation of phytoremediation technique for remediation of heavy metals in these petroleum contaminated soils was also part of the purpose.
Arsenic contaminated environments: bioremediation perspective from molecular analysis on the bacterial arsenical metabolism
© Aristotle University of Thessaloniki (6/2009)
The metalloid arsenic (As) can be released from geological formations and it is widely used in anthropogenic activities (industry, agriculture, etc.) contaminating several aquatic and soil environments. The arsenate As(V) and arsenite As(III) can be subject to microbiologically oxidation, reduction and methylation reactions. Indeed, bacterial metabolisim of arsenical species in the environment is critical in the As cycle. In the present study, novel aerobic bacterial strains responsible for the oxidation and reduction of As were isolated in water samples supplemented with arsenite or arsenate.
Überschnittene Großlochbohrung als Bodenaustauschverfahren bei der Sanierung ökologischer Altlasten
© wvgw Wirtschafts- und Verlagsgesellschaft Gas und Wasser mbH (3/2016)
Der Austausch kontaminierten Bodens in der grundwassergesättigten Zone stellt hohe Ansprüche an den Tiefbau sowie den Arbeits- und Immissionsschutz. In den letzten Jahren werden zunehmend überschnittene Großlochbohrungen als Sanierungsverfahren angewendet, da diese kleinräumigen Verfahren bis in größere Tiefen anwendbar sind, ohne umfangreiche Verbauarbeiten oder Grundwasserabsenkungen vornehmen zu müssen. Anhand einer erfolgreichen Anwendung dieser Sanierungsmethode auf dem Grundstück einer ehemaligen chemischen Reinigung in Berlin werden Planung und Ausführung dieser Methode erläutert.
Chemical fractionation and phytoextraction capacity of maize plant grown on chromated copper arsenate soil
© Aristotle University of Thessaloniki (6/2009)
A pot experiment was performed to study the single and sequential extraction of As, Cr and Cu in chromated copper arsenate (CCA) contaminated soil and the potential of maize (Zea mays) for the removal of the metals from the CCA contaminated soil.
Bioremediation of petroleum-contaminated soil using landfarming technique: Influence on soil biological and chemical properties
© Aristotle University of Thessaloniki (6/2009)
Petroleum hydrocarbons are a carcinogenic group of contaminants which are widely distributed in the environment. In this study, bioremediation of two petroleum-contaminated soils around the Tehran Oil Refinery (S1 and S2) using landfarming technique was evaluated. The effect of this technique on some biological and chemical properties of investigated soils at the end of each month of the experimental period (4months) was also part of the goal.
