Table 2 Concentrations of the PCB and OH-PCB congeners identified in human milk from the Faroe Islands. The samples were pooled with 10 mothers in each pool, duplicate samples (A/B) were analyzed in parallel. ΣPCB consists of CB-105, CB-118, CB-128, CB-138, CB-146, CB-153, CB-156, CB-170, CB- 180, CB-183 and CB-187 and ∑OH-PCB is the sum of 4-OH-CB146 and 4-OH-CB187.

From: A retrospective study of PBDEs and PCBs in human milk from the Faroe Islands
