Estimates of the Biologic Half-Life of Polychlorinated Biphenyls in Human Serum

Abstract
To the Editor: In 1984, we conducted a study of 114 people who were considered to be at high risk of exposure to polychlorinated biphenyls (PCBs) because of characteristic activity patterns in contaminated areas around three waste dump sites in Bloomington, Indiana. Of these, five current and retired electrical-equipment manufacturing workers (Participants 1 through 5) had serum PCB levels measured in 1977 as less chlorinated PCB (Aroclor 1242) and more highly chlorinated PCB (Aroclor 1260).1 The change over the seven-year period is shown in Table 1. We also measured the changes in serum PCB levels in six participants without known current . . .
