General description

Polychlorinated biphenyls (PCBs) belong to the class of highly toxic pollutants commonly found in various environmental matrices and food products. They find a variety of applications as flame retardants, plasticizers, dielectric and heat transfer fluids, etc.

Application

PCB No 28 solution may be used as an analytical reference standard for the determination of the analyte in water samples using gas chromatography coupled to mass spectrometry (GC-MS).

The capability of Rhizobium meliloti on degrading 2,4,4'-trichlorobiphenyl and 18 kinds of polychlorinated biphenyl congener mixtures was studied by shaking flask experiment. The results showed that the degradation capability of Rhizobium meliloti to 2, 4, 4'-trichlorobiphenyl increased gradually with the

Sorption behaviors of PCB28 to phosphatidylcholine (PC)and triglyceride (TG) were studied. Results showed that sorption equilibrium could be achieved in 8 h for PCB28, and the sorption amount on PC was higher than that of TG when the initial PCB28

The environmentally prevalent polybrominated diphenyl ether (PBDE) #47 and polychlorinated biphenyls (PCBs) #28 and #118 were challenged for 24 hours with a novel biomass-supported Pd catalyst (Bio-Pd(0)). Analysis of the products via GC-MS revealed the Bio-Pd(0) to cause the challenged

Resting cell assay and soil microcosms were set up to investigate the biodegradation capability and metabolic intermediate of polychlorinated biphenyls (PCBs) by a rhizobial strain Sinorhizobium meliloti. Biodegradation was observed immediately after 2,4,4'-TCB was supplied as a sole source of
