Proposed PCB congener groupings for epidemiological studies.
Health effects related to polychlorinated biphenyls (PCBs), which include 209 possible congeners exhibiting a variety of chlorine substitution patterns (Fig. 1), are the subject of numerous research investigations. Individual members of this family evoke diverse responses in experimental models and in humans. Certain PCB congeners mimic hormones and are neurotoxic (1-3). Others produce a dioxin...
متن کاملStepping backward to improve assessment of PCB congener toxicities.
Polychlorinated biphenyls (PCBs) are ubiquitous global contaminants that have been intensively investigated for three decades. They are broad-acting toxicants occurring in complex mixtures and accurate risk assessment has proven to be elusive. Focusing on a limited set of end points and emphasizing a fixed set of congeners have led to more streamlined data sets that are meant to expedite hazard...
متن کاملSerum PCB levels and congener profiles among US construction workers
BACKGROUND The presence of PCB in caulking (sealant) material found in masonry buildings has been well-documented in several countries. A recent investigation of 24 buildings in the greater Boston area found that 8 buildings had high PCB levels in caulking materials used around window frames and in joints between masonry blocks. Workers removing caulking material have been shown to have elevate...
متن کاملSerum PCB levels and congener profiles among teachers in PCB-containing schools: a pilot study
BACKGROUND PCB contamination in the built environment may result from the release of PCBs from building materials. The significance of this contamination as a pathway of human exposure is not well-characterized, however. This research compared the serum PCB concentrations, and congener profiles between 18 teachers in PCB-containing schools and referent populations. METHODS Blood samples from ...
متن کاملComplete PCB Congener Distributions for 17 Aroclor Mixtures Determined by 3 HRGC Systems Optimized for Conlprehensive, Quantitative, Congener-Specific Analysis
Three HRGC systems (1: 30m DB-XLB capillary with MS-SIM detection; 2: 60m DB-XLB capillary with full-scan, ion.trap MS detection; and 3: Parallel dual·column DB·17 and series-coupled HP5IHT5 with ECD detection) were used to completely charac· terize multiple lots of 8 different·numbered Aroclor mixtures by quantitative calibration against 9 solutions containing primary standards of all 209 PCB ...
