This study is to assess PCB levels in five frequently
consumed fish species in Taiwan, tilapia, milkfish, white
pomfret, hairtail, and cod. Seventeen congeners were
measured in fillet samples purchased from major markets
in northern, central, and southern Taiwan. All 136 samples
had traces of PCBs. The median concentrations were 0.18,
0.46, 0.62, 0.69, and 7.34 ng/g wet wt and 1.01, 0.28, 1.14,
5.06, and 19.3 pg-WHO-TEQ/g lipid in tilapia, milkfish, white
pomfret, hairtail, and cod samples, respectively. Cod (the
imported fish) had the highest wet weight PCB concentrations.
The fish caught off-shore (white pomfret and hairtail)
had higher levels than the farmed fish (tilapia and milkfish).
The congener profiles varied among species. PCB 105/153 and 126 accounted for more than 28% and 53% of the
2,3,7,8-tetrachlorodibenzo-<i>p</i>-dioxin equivalents (WHO-TEQs) in hairtail and cod, respectively; while PCB 156 was
the major TEQ contributor in the other species. The
estimated median PCB intake of the general public from
consumption of the five species ranged from 0.000023 to
0.048 pg-WHO-TEQ/kg/day. It was also found that samples
farmed or caught along the southern coast had higher
PCB levels than those from other parts of Taiwan, indicating
possible elevated PCB contamination around that area.
