Discussions are being made on cloning of PCB decomposing genes, and breeding of decomposing bacteria that have wide PCB decomposing spectra.
These bacteria desorb metha-ordered chlorine. and other companies have isolated bacteria that dechlorinate PCB decreasingly under an anaerobic condition. These stocks decompose third and fourth ordered open high-chlorine PCB. has searched for two kinds of bacteria stocks that introduce O2 preferentially into the third and fourth orders. The decomposition through this path becomes difficult when the number of displaced Cl increases, and PCB with Cl displaced in only one of the rings decomposes more easily than PCB with the same number of Cl in both rings. PCB that is decomposed in this 2, 3-dioxygenaze path requires at least one of the second and third orders to be open. Aerobic PCB decomposition using soil bacteria generally goes through introduction of O2 into second and third orders of a biphenyl ring, ring cleavage, and hydrolysis, and generates benzoate finally. This paper generalizes knowledges acquired so far on bio-remediation of PCB. PCB no biseibutsu bunkaiĮnergy Technology Data Exchange (ETDEWEB)įurukawa, K [Kyushu University, Fukuoka (Japan). The i PCB6 equiv levels for the 6.5 and 10 pg/g benchmarks of dl PCB-TEQ05 are about 50 and 120 ng/g ww, respectively, which are lower than the corresponding i PCB6 limits of 125 and 300 ng/g ww set by the European Union. Relationships among the existing and new i PCB schemes have been presented to facilitate their interconversion. Measurement of ∑ PCB based on a more detailed analysis (50+ congeners) is also overall a good approach for assessing PCB contamination and to track PCB origin in fish.

Overall, novel i PCB3 ( PCB 95, 118, and 153), i PCB4 (i PCB3 plus 138) and i PCB5 (i PCB4 plus 110) presented in this study and existing i PCB6 and i PCB7 are the most optimal indicators, while the current i PCB3 should be avoided.
The coefficients of determination (R(2)) for regressions conducted using logarithmically transformed data suggest that inclusion of an increased number of PCBs in an i PCB improves relationship with ∑ PCB but not dl PCB-TEQs. Here, using an extensive data set, we examine the performance of existing i PCB3 ( PCB 138, 153, and 180), i PCB6 (i PCB3 plus 28, 52, and 101) and i PCB7 (i PCB6 plus 118) schemes, and new i PCB schemes in estimating total of PCB congeners (∑ PCB) and dioxin-like PCB toxic equivalent (dl PCB-TEQ) concentrations in sport fish fillets and the whole body of juvenile fish. Measurements using a subset of indicator PCBs (iPCBs) have been considered appropriate however, inclusion of different PCB congeners in various i PCB schemes makes it challenging to readily compare data.

Technical mixture-based total PCB measurements are unreliable due to weathering and degradation, while detailed full congener specific measurements can be time-consuming and costly for large studies. Polychlorinated biphenyls (PCBs) remain chemicals of concern more than three decades after the ban on their production.
