Summary
ABSTRACT Placental abruption results in hemorrhage, ischemia, and fetal hypoxia, placing a tremendous health burden on both the mother and the newborn. Efforts to understand the etiology of this devastating obstetrical complication have been disap- pointing. This project will delineate environmentally-associated pathways to abruption and determine the impact of pol- lutant triggers that are implicated in acute versus chronic placental abruption. Given that one-fourth of all abruption cases have an acute etiology and 15% of abruptions may recur in future pregnancies, the role of environmental t
