“…Congeners #153 and #180 were not detected above their detection limits of 18.9 and 10.0 ng in 100 lg of the PCB mixture of Kanechlor-300/400 used in this study. The sum of the PCB congeners determined as described above corresponded to 83.0% (w/w) of the technical formulation of Kanechlor-300 and -400 reported by Kim et al (2004). The total recovery of PCBs by chloroform-methanol extraction from the soil culture spiked with 100 lg of the PCB mixture was 92.9 ± 5.5% (w/w).…”

Polychlorinated biphenyls (PCBs) in Kanechlor-300 and -400 mixtures dissipated significantly compared with a sterilized control under anaerobic conditions in three Japanese paddy soils with no history of PCB contamination, demonstrating the anaerobic microbial degradation of PCBs. The PCB-degrading activity was maintained successfully in a static flooded soil medium for more than 3 years by serial transfer at intervals of 56 days (13 transfers). Ortho-, meta-, and para-substituted PCBs, 15.2 ± 9.9 mol% in total, were significantly degraded after 56 days of incubation. Analysis of menaquinones-6 and -7 and cloning of 16S rRNA gene fragments from a polymerase chain reaction denaturing gradient gel electrophoresis (DGGE) profile indicated the predominance of Firmicutes in the consortium. A PCR-based identification of the gene fragments showed the frequent presence of Desulfitobacterium sp., but not Dehalobacter sp. or Dehalococcoides sp., in the consortium. It is proposed that Japanese paddy soils with no history of PCB contamination contain an anaerobic microbial consortium consisting predominantly of Firmicutes that have the potential for anaerobic degradation of PCB.

“…The POP concentrations in the stack flue gases of the EAFs are listed in Table 5 lists the POP concentrations in the stack flue gases/ exhausts of various emission sources, such as incinerators (Kim et al, 2004;Wang et al, 2010a), sinter plants (Kuo et al, 2012;Wang et al, 2003c), EAFs (Lee et al, 2005;Wang et al, 2010c;), power plants (Dyke et al, 2003;Hutson et al, 2009;) and diesel engines (Wang et al, 2010b). As yet, no data regarding PCDEs and PBBs in flue gases emitted from combustion facilities have been reported in the literature.…”

A long-term sampling system, called the Adsorption Method for Sampling of Dioxins and Furans (AMESA), was used for long-term sampling (up to 168 hours) of an electric arc furnace (EAF) to obtain the representative flue gas samples. In order to have a comprehensive view of the emissions of persistent organic pollutants (POPs) from EAFs, six POPs, including polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), polychlorinated diphenyl ethers (PCDEs), polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs), were investigated. Tests showed the breakthroughs of PBDD/Fs and PBDEs are much larger (8.9%-43%), while the others are less than 3%. A significant increase in breakthrough with the increase in halogen numbers is observed, because highly halogen-substituted POPs tend to partition to the particulate-phase. Except for PCBs and PCDEs, whose percentages of the POPs in the rinses to the total POPs collected from the long-term samples (cartridges + rinses) are less than 7%, those of the other POPs are all greater than 30%. Therefore, the solvents from the rinses of the sampling probe and other components need to be combined with an XAD-2 cartridge for analyses. The PCBs and PBDEs are the most abundant pollutants in the stack flue gases of the EAF, and their mass concentrations are one to three orders higher than those of the other POPs. With regard to POPs with dioxin-like toxicity, the percentages of the contributed toxicities by PCDD/Fs, PCBs and PBBD/Fs are 87.1%, 11.7% and 1.2%. The close association that PBDEs and PBDD/Fs have with the concentrations and congener profiles is not present for PCDEs and PCDD/Fs, suggesting the need for further studies of the formation mechanisms of these analogues.

A specific dioxin composition was detected in some sediment samples collected from the highly polluted Furuayase River, Japan. The dominant tetrachlorodibenzofuran (TeCDF) congeners in the samples were 1,3,7,3,7,3,7,3,7,. To identify the sources of the pollution with the specific dioxin composition, the dioxin compositions were studied in samples of drainage discharge water, sewage discharge water, and sludge in the sewage works from four chemical factories located in Furuayase River drainage basin. The specific composition was detected in the sewage discharge water and the sludge in the sewage works of one factory. This factory had previously produced 2,4,6-trichlorophenylhydrazine (TCPH) as an intermediate in the synthesis of a photographic medicine. It was investigated whether dioxin impurities were present in commercial TCPH reagents and whether 1,3,7,8-/1,3,7,9-TeCDF by-products might be formed during manufacture of TCPH. The dioxin homologue and congener profiles from one commercial reagent were similar to those of the sewage discharge water and sludge in the sewage works from the aforementioned factory. Our results indicated a possible pathway for the generation of 1,3,7,9-TeCDF during manufacture of TCPH.
