Blood values of PCB-exposed and control subjects. Blood values (means and standard deviations) of the PCB-exposed subjects and the control group (median PCB-28 and -101 levels were below 0.01 μg/l in controls). Expected values (background exposure) were estimated for each exposed subject from age-group related reference values [median PCB-plasma values for PCB-138, -153 and -180 according to 37].
