Ze-Yu Yang et al.
Chemosphere, 72(10), 1435-1440 (2008-07-04)
To verify a theoretical mass balance and multiple compartment partitioning model developed to predict freely dissolved concentrations (FDCs) of hydrophobic organic chemicals (HOCs) using negligible depletion-solid phase microextraction (nd-SPME), a series of sediment slurry experiments were performed using disposable poly(dimethyl)siloxane
Suleyman Sandal et al.
Mutation research, 654(1), 88-92 (2008-06-25)
Polychlorinated biphenyls (PCBs) are known to be carcinogenic, but the mechanisms of this action are uncertain. Most, but not all, studies have concluded that PCBs are not directly mutagenic, and that much if not all of the carcinogenic activity resides

Environmental toxicology, 27(3), 185-191 (2011-02-24)
Cultured porcine endothelial cells were used to determine the effects of several congeners of polychlorinated biphenyls (PCBs) on cell viability and changes induced by these congeners on levels of intracellular calcium and reactive oxygen species (ROS). Cultured endothelial cells were

Our preceding studies have reported that 2,2',5,5'-tetrachlorobiphenyl (tetraCB)(CB52) is mainly metabolized to 3-hydroxy (OH)-metabolite by phenobarbital (PB)-inducible cytochrome P450 (P450) isoforms such as CYP2B1 and CYP2B18. In this study, the metabolism of CB52 by liver microsomes of untreated and PB-treated

We analyzed the vapor phase atmospheric concentrations of representative persistent chemicals (i.e., α- and γ-hexachlorocyclohexane, phenanthrene, PCB-18 and PCB-52) in samples collected at a remote site near Eagle Harbor, Michigan, and at an urban site in Chicago, Illinois, using four
