Michigan PBB Cohort

Principal Investigator:
Institution:
Emory University
Location:
Michigan
Number of Participants::
7,500
Brief Description::
This is a multi-generational cohort study to assess the effects of polybrominated biphenyl (PBB) exposure on a number of outcomes in men and women and their offspring after a widespread exposure incident in 1973. The Michigan PBB Registry was established in 1976 and enrolled approximately 4,000 farmers, chemical workers, and others with PBB exposure risk; children and grandchildren of original registrants have also been enrolled.
