Kodavanti et al. exposed adult male Long-Evans rats to the PCB mixture Aroclor 1254 containing PCB 153, PCB 180 as well as PCB 52 [ 5].
The b-galactosidase activity of PCB standards ranged from 18.35 % (PCB 101) up to 85.88 % (PCB 118), with PCB 118 resulting the most estrogenic in the yeast assay.
Three PCB congeners were among the target chemicals: PCB 52, PCB 105, and PCB 153.

After 12 months, a negligible quantity of Aroclor 1248 (an average of 0.24%) and the Σ 7 key PCB congeners (ΣPCB7; IUPAC No.: PCB 28, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153 and PCB 180) were leached from the soils into the water collected under the lysimeters (an average of 0.32%).
In the Rhine and the Rur, PCB 153 comprised 40%to43%3% of the sum of indicator PCBs in eel, PCB 138 accounted for 23%to28%8% and PCB 180 for 12%to16%6%.
PCB 28 did not exceed 1% (Figure 2).
Fish were exposed to PCB 47 and PCB 153 in the diet (0, 0.2 and 1.0 mg/kg body weight/day) for 30 days and to PCB 77 (0.01 and 0.1 mg/kg body weight/day) for 15 days.
The PCB 2,2,2-trichloroethyl sulfate diesters 1 10 and selected, structurally-related methoxylated PCBs 11 and 12(Figure 1) were analyzed by electron ionization mass spectrometry (EI-MS).
The pattern of PCBs in suspended matter varied slightly with PCB 138 being the most dominant congener in the Rhine while in the Rur, PCB 153 had a slightly higher percentage than PCB 138.
