Polychlorinated biphenyls are toxic compounds which have accumulated in river sediments in Eastern Slovakia. Bioaccumulation could cause even cancer. Radiation degradation with electrons is new and perspective method to dechlorinate PCBs in sediment matrix. We tested the influence of two difference chemical pretreatments and electron irradiation on PCB contaminated sediments.

Artificial Ponds

Polychlorinated biphenyls (PCBs) originating from the sediment were taken up by zooplankton and fish in artificial ponds in the field. PCB uptake in zooplankton was concentration dependent, as levels of the residues in water varied seasonally. Planktivorous fish accumulated the compounds to high levels at high summer concentrations of PCBs in the water, after which elimination was slow. Levels of PCBs in benthic fishes continuously increased during the 1.5-yr study. The results show that chlorinated hydrocarbons deposited in sediments are available to aquatic organisms.

Pcb Dechlorination

ABSTRACT Anaerobic microbial dechlorination is an important step in the detoxification and elimination of polychlorinated biphenyls (PCBs), but a microorganism capable of coupling its growth to PCB dechlorination has not been isolated. Here we describe the isolation from sediment of an ultramicrobacterium, strain DF-1, which is capable of dechlorinating PCBs containing double-flanked chlorines added as single congeners or as Aroclor 1260 in contaminated soil. The isolate requires Desulfovibrio spp. in coculture or cell extract for growth on hydrogen and PCB in mineral medium. This is the first microorganism in pure culture demonstrated to grow by dehalorespiration with PCBs and the first isolate shown to dechlorinate weathered commercial mixtures of PCBs in historically contaminated sediments. The ability of this isolate to grow on PCBs in contaminated sediments represents a significant breakthrough for the development of in situ treatment strategies for this class of persistent organic pollutants.

Degradation Ability

AbstractThe paper deals with the application of two perspective and promising bioremediation approaches, bioaugmentation and biostimulation, applied to sediment contaminated with polychlorinated biphenyls (PCBs) with the aim to enhance biodegradation of PCBs. Sediments were sampled from Strážsky canal, an industrial waste canal that flows from a former PCB-factory through the Laborec river into the Zemplínska šírava water reservoir, all located in the eastern part of Slovakia. Bioaugmentation of sediments was performed in microcosms using two bacterial isolates with PCB-degradation ability obtained from the contaminated sediment:
