Colestimide reduces blood polychlorinated biphenyl (PCB) levels.
1. A: Blood level of PCBs before and after the treatment in nine subjects. Closed circles show blood PCB level of each subject. Open circles show the mean blood level of PCB. B: Correlation between initial PCB concentration and reduction ratio (%) of PCB after colestimide treatment. (R= 0.64) C: Correlation of alteration in PCB and dioxin level after colestimide treatment. Data expresses the pe...
متن کاملPreferential biomagnification of aryl hydrocarbon hydroxylase-inducing polychlorinated biphenyl congeners in the Lake Michigan, USA, lower food web.
Preferential biomagnification of 14 dioxin-like polychlorinated biphenyls (PCBs) was determined in lower-trophic-level organisms of the Lake Michigan, USA, food web. Bioaccumulation of these coplanar, aryl hydrocarbon hydroxylase (AHH)-inducing PCB congeners and total PCBs in phytoplankton, zooplankton, Mysis relicta, and Diporeia sp. were studied for two locations in Lake Michigan over time. T...
متن کاملInfluence of trophic position and spatial location on polychlorinated biphenyl (PCB) bioaccumulation in a stream food web.
We tested the ability of delta15N-derived trophic position (TP) to predict polychlorinated biphenyl (PCB) concentrations in a historically contaminated stream (Twelvemile Creek, SC). We analyzed sediment, four types of organic matter, 27 macroinvertebrate taxa, and 25 fish species from six sites spanning 25 stream km. SigmaPCBs were high across sites (mean fish = 2505 ng g(-1) wet), with little...
متن کاملThe biomagnification of polychlorinated biphenyls, toxaphene, and DDT compounds in a Lake Michigan offshore food web.
The biomagnification of polychlorinated biphenyls (PCB), toxaphene, and the DDT family of metabolites was investigated in the epibenthic Mysis relicta (mysid), the benthic Pontoporeia hoyi (amphipod), plankton, particulate flux, surficial sediments, and Myoxocephalus thompsoni (deepwater sculpin) in southeastern Lake Michigan. DDE was the most strongly biomagnified compound, increasing 28.7 tim...
متن کاملA reassessment of the nomenclature of polychlorinated biphenyl (PCB) metabolites.
Polychlorinated biphenyls (PCBs) are a widespread class of persistent organic chemicals that accumulate in the environment and humans and are associated with a broad spectrum of health effects. PCB biotransformation has been shown to lead to two classes of PCB metabolites that are present as contaminant residues in the tissues of selected biota: hydroxylated (HO) and methyl sulfone (MeSO2) PCBs...
