Persistent organic pollutants (POPs) are compounds with aromatic rings that degrade slowly or incompletely and thus persist in the environment. These POPs leave an environmental legacy long after the compound is no longer being produced or used, in part because of their ability to accumulate in food chains and expose higher-order predators, including humans. In this issue of JAMA Pediatrics, Ouidir et al1 evaluate the association between maternal exposure to POPs, some of which have already been banned in the United States, and long-term fetal growth.
