ASSESSMENT OF ELECTROCHEMICAL TREATMENT EFFICIENCY FOR ARTIFICIALLY CONTAMINATED SOIL WITH PAHs AND PCBs
Journal Title: Present Environment and Sustainable Development - Year 2013, Vol 7, Issue 2
Abstract
Soil is an extremely complex medium and different soil fractions and constituents have very variable degrees of reactivity to any introduced compounds. Thus, the simplicity of the “cause and effect” situations that can be obvious in air and water pollution incidents is usually unattainable. The objective of the present paper is to present results obtained during an experimental campaign that took place in the framework of a research project co-funded by the European Regional Development Fund. Based on the preliminary results, it can be said that the electrochemical treatment can be considered a viable solution that can be applied in the case of an organic contamination. The remediation of these contaminants is essential to promote public health, environmental quality, and the economy. In the present paper, the application of electrochemical treatment of polychlorinated biphenyls (PCBs) and polyaromatic hydrocarbon (PAHs) contaminated soils was investigated. For the present research, three tests have been analyzed. The conclusion showed that the electrochemical treatment could be a viable solution for the removal of different types of PCBs and PAHs. If an analysis is to be done by comparing the obtained results, it can be noticed that after each treatment we have lower concentrations of PCBs and PAHs; most of them are lower than the strictest legal limit according to Order 756/1997 (the intervention thresholds for sensitive use).

CONSIDERATIONS ON TEMPERATURE INVERSIONS IN THE LOWER TROPOSPHERE IN THE 2001-2002 COLD SEASON, SOUTH OF THE CARPATHIAN MOUNTAINS
Temperature inversions are characterized by negative vertical thermal gradients (Donciu, 1953, Ţâştea, 1965, Bogdan, 1971, Neacşa, Frimescu, 1981). The most frequent manifestation is in the depression areas becau...
