Reclaiming Polluted Marine Sediments. A Case History
The Development Plan of Taranto port (S. Italy) predicts the dredging of approx.20 Mt sediments, ≥10% of which are polluted. By appointment of Italian Environment Ministry, a detailed experimental investigation was carried out at laboratory and pilot-scale levels on the best available techniques to reclaim the polluted sediment so to reuse it in a technic and cost effective manner. A short pre-...
متن کاملPolychlorinated Biphenyl Sorption and Availability in Field-Contaminated Sediments†
Traditional and new relationships of polychlorinated biphenyl (PCB) distribution among the solid phases, the free aqueous phase, and biolipids are comprehensively reviewed using seven well-characterized freshwater and marine sediments polluted with PCBs. The traditional relationship relating free aqueous concentration and biolipid concentration to sediment total organic carbon, compound octanol...
متن کاملBioremediation of oil polluted marine sediments: A bio-engineering treatment.
The fate of hydrocarbon pollutants and the development of oil-degrading indigenous marine bacteria in contaminated sediments are strongly influenced by abiotic factors such as temperature, low oxygen levels, and nutrient availability. In this work, the effects of different biodegradation processes (bioremediation) on oil-polluted anoxic sediments were analyzed. In particular, as a potential bio...
متن کاملAerobic Polychlorinated Biphenyl-Degrading Bacteria
Several bacterial isolates were characterized based on their abilities to degrade specific polychlorinated biphenyls (PCBs) and their 16s rRNA gene sequences. The members of one group of bacteria consisting of Alcaligenes species, including the PCB-degrading bacterium Alcaligenes eutrophus H850, had strong abilities to degrade a broad range of PCBs but not the di-para-chlorine-substituted conge...
متن کاملidentification of aerobic polychlorinated biphenyl degrading bacteria
background: polychlorinated biphenyls (pcbs) are synthetic aromatic compounds containing two benzene rings with one to ten chlorine atoms. there are concerns about the health risks of these compounds in the environment due to their toxicity, persistence, and biological accumulation. pcbs wastes must be treated before being discharged to the environment because they will pollute the water, soil,...
