Abstract

We compared concentrations of PCB congeners between conventional 80 degrees C alkali digestion method and 30 degrees C alkali digestion method using 22 individual blood samples collected during 2009 annual Yusho examinations. The mean concentration of tri-CB in 30 degrees C alkali digestion method was lower than that of conventional method. However, concentration of total PCBs, 2,3',4,4',5-pentaCB (PCB118), 2,2',4,4',5,5'-hexaCB (PCB153) and 2,3,3',4,4', 5-hexaCB (PCB156), which were used as index for Yusho diagnosis, were equivalent between the methods. It was considered that the 30 degrees C alkali digestion method was available for blood PCB congener specific analysis in Yusho diagnosis.
