Influence of increasing chlorine content on the accumulation and metabolism of polychlorinated biphenyls (PCBs) by Paul's Scarlet rose cells
Technical Report
·
OSTI ID:5584537
Four radiolabeled congeners of biphenyls with increasing chlorine content (biphenyl; 1-monochlorobiphenyl; 2,2',4,4'-tetrachlorobiphenyl; and 2,2',4,4',5,5'-hexachlorobiphenyl) were provided to suspension cultures of rose (Rosa sp. vc. Paul's Scarlet) for four days. Both the kinetics of (14)C exchange between the cells and medium, and the metabolism of the parent compounds depended on the chlorine content of the congeners. Analysis of both the cells and their medium showed that of the recovered radioactivity 88%, 86%, and 3% of the biphenyl, 1-PCB, and 2,2',4,4'-PCB were metabolized respectively to polar and insoluble residue products. The 2,2',4,4',5,5'-PCB did not appear to be metabolized.
