Key result
Different analytical calculation methods yield widely varying serum PCB levels in formerly exposed workers.
Why the study?
The variability and comparability of serum PCB measurements using different analytical methods in exposed populations were unclear.
Population
Capacitor workers formerly exposed to commercial PCBs Aroclors 1016, 1242, and 1254
Comparison
Different analytical calculation methods for serum PCB levels
Design
Observational study

Analytical variability in commercial serum PCB assays warrants interpretive caution; leaves open standardization of exposure metrics in occupational research.
Observational
Reportable serum PCB values vary widely depending on the analytical calculation method used, reflecting isomer distribution and clearance patterns.
Lawton et al. (1985) conducted an observational in Former direct exposure to commercial PCBs. Commercial PCBs (Aroclors 1016, 1242, and 1254) was evaluated on Serum PCB levels. In capacitor workers formerly exposed to PCBs, reportable serum PCB levels varied widely (from 19 ppb to 1905 ppb) depending on the analytical calculation method used.
