Table 5.

The congener enrichment factors (CEFs), area in km² of zone 1 and combined areas of zones 1+2 and 1+2+3 for individual PCB congeners and the midpoint congener serum concentration in ng/g lipid. The congeners were ranked based on the size of zone/s. The mean±SD area for all congeners of zone 1 is 235.75 ± 188.56 km², zones 1+2 1523.7 ± 902.44 km² and zones 1+2+3 3196.8 ± 1535.92 km².
