“…PBB irradiated by ultraviolet light forms lower brominated biphenyls (13). The persistence of PBBs and the possible degradation of the ultraviolet products is consistent with the evidence reported for PCBs which shows that the more heavily chlorinated moieties (penta or greater) are resistant to degradation though many lesser chlorinated biphenyls are metabolized (14)(15)(16).…”

“…In the second experiment the biodegradability of TCBTs in activated sludge is compared with the biodegradability of PCBs, whose biodegradability in activated sludge is reported in the literature. Several studies (9,10) reported the capability of activated sludge to degrade mono-and dichlorobiphenyl isomers or mixtures.…”

“…This activated sludge did not seem to be able to biodegrade mono-and dichlorobiphenyls. The activated sludge, which was previously reported to be able to biodegrade mono-and dichlorobiphenyls (9,10), may have been exposed to these PCBs for a long time.…”

There was no evidence for significant biodegradation of either TCBTs or PCBs in activated sludge. In contrast, cultures of strain JB1 did degrade PCB 40, but again there was no evidence for degradation of TCBTs. Although no final conclusions can be drawn from these results about the biodegradability of TCBTs, they do indicate that TCBTs are environmentally persistent compounds.

“…23 Analysis of extracts from the medium by gas chromatography and UV spectroscopy revealed that the rates of biodegradation were as follows: biphenyl > Aroclor 1221 >MCS 1043 (30% Cl)> Aroclor 1016 > Aroclor 1242 > Aroclor 1254. Comparison of chromatograms of Aroclor 1221 and extracts from sludge exposed to this mixture showed that the minor, highly chlorinated, components were most resistant to degradation and that these resembled the major components of Aroclor 1242.…”
