Metabolic transformation shapes PCB and PBDE patterns in beluga whales (Delphinapterus leucas)
While the accumulation of persistent contaminants in marine mammals can be attributed directly to their prey, the role of metabolism in shaping patterns is often overlooked. Here we investigate the role of metabolic transformation in influencing polychlorinated‐biphenyl (PCB) and polybrominated diphenylether (PBDE) patterns in offshore and nearshore groups of beluga whales (Delphinapterus ...

Analysis of Polychlorinated Biphenyls in Fish Oil Using Supelclean EZ-POP NP, Silica Gel SPE, and an SLB-5ms GC Column
Polychlorinated biphenyls (PCBs) were once widely used in many industrial and commercial applications such as insulating fluids, dielectrics, and lubricants. This included their extensive use in electrical transformers. PCB use has been banned in many countries, and the Stockholm Convention currently prohibits their production and use1. However, PCBs may still be released into the environment ...

Continued Use of PCB-Contaminated Concrete Through Implementation of the 40 CFR 761.30(p) Use Authorization
The 40 CFR 761.30(p) use authorization for PCB-contaminated porous surfaces was applied to concrete floors at an electric utility’s transformer shop and PCB storage building. This authorization allows PCB-contaminated concrete to be managed in place while it remains in service, provided that it is surface washed, encapsulated, and marked to indicate the presence of PCBs that will ultimately need ...

Biomagnification of polychlorinated biphenyls in a harbor seal (Phoca vitulina) food web from the Strait of Georgia, British Columbia, Canada
Polychlorinated biphenyl (PCB) biomagnification was characterized in a harbor seal food web in the Strait of Georgia, British Columbia, Canada. Trophic magnification factors (TMFs) for PCBs averaged 3.6, with a range of 0.7 to 9.4. The TMFs for individual congeners correlated with log Kow (r2 = 0.56, p < 0.001), reflecting the role that physicochemical properties play in driving the ...

Surface Decontamination of Poly-Chlorinated Biphenyls (PCBs) using DeconGel� Formulations 1101 and 1102
OBJECTIVE: Surface decontamination determination of DeconGel® formulations 1101 and 1102 on aluminum, carbon steel, and concrete surfaces contaminated with PCB (Aroclor 1016) oil following a modified version of Environmental Protection Agency (EPA) SW-846 Method 8082A, “Determination of PCBs by Gas Chromatography”. HAZARDOUS MATERIALS RELEVANCE: PCBs were widely used ...

Assessment of the Environmental Impact of Military Activities During the Yugoslavia Conflict
1. Executive Summary Assessment Method:The study was carried out over a period of ten days by a team of expert staff from the Regional Environment Center for Central and Eastern Europe (REC) and other contracted country experts. A framework was prepared by REC headquarters and the REC's country offices in the five selected countries gathered information and data. Additional experts were hired to ...
