The Effects of Arbuscular Mychorrizal Fungi on the Transfer of Heavy Metals and Oxidative Stress related Parameters in Sunflower Exposed to Multi-element Pollution

This study was motivated by the presence of a large number of pollutants both in the free air To achieve this purpose, three operational objectives have been identified: -characterize the distribution of heavy metals in soil compartments and primary producers; -characterize the effect of polluted soil inoculation with mychorriza fungi on primary producers, measured by assessment of oxidative stress parameters; -proposing solutions to remedy the polluted area. There were identified the dominant plant species in Slatina polluted area and a literature screening was conducted in order to identify an effective mechanism for protection of plants against heavy metal pollution. The dominant plant species in the area are: corn (Zea mays L.) and sunflower (Helianthus annuus L). Previous studies conducted in Slatina polluted area, as a result of obtaining and processing aluminum, have established how much fluoride pollution has spread to human and animal populatio

Electroactive properties of a new azulene thioxo-imidazolidin-4-one ligand for modified electrodes

The electrochemical characterization of a new synthesized azulene compound (Z)-5-((5-isopropyl-3,8-dimethylazulen-1-yl)methylene)-2-thioxoimidazolidin-4-one (L) using cyclic voltammetry, differential pulse voltammetry and rotating disk electrode is presented. Chemically modified electrodes were obtained by successive scanning or by controlled potential electrolysis using different electrode potentials or charges. The new modified electrodes were tested in solutions containing different concentrations of the following heavy metals: cadmium, lead, mercury and copper. A good analytical response was obtained for Pb2+
