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

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

There are 75 full length cytochrome P450 (CYP) genes known in the genome of the nematode Caenorhabditis elegans. The individual biological functions of the vast majority are mostly as yet unknown. Here the impact of cytochrome P450 isoforms on the

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

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
