after reduction by SnCl2 (FIMS 100 P.E.). For PCBs, analyses were made on a Carlo
Erba HR gas chromatograph 8000 Top with automatic injection system and with
an electron capture detector ECD-800, Ni63 (temperature: 330 C). For all the
analyses a fused-silica capillary column DB-5 Supelco (length = 30 m, inside diameter
0.25 mm and film thickness 0.25 lm), was used. Hydrogen at a flow rate of
1 ml/min was used as gas carrier, nitrogen as make-up gas 60 ml/min. The individual
PCB congeners were determined against the corresponding individual standards
obtained from ULTRA Scientific, Inc. (chemical purity 99%). The limits of detection
(LOD) was 5 pg g1 fish muscle on a wet wt basis for the PCB congeners.
