In recent years, maternal-fetal medicine has responded to the risk that environmental toxins pose to pregnancy, calling for action to identify and reduce exposure to toxic environmental agents while addressing the consequences of such exposure. However, despite increasing awareness, a recent survey suggests that most doctors don’t discuss exposure to pollutants with their pregnant patients. While chemicals are virtually impossible to avoid completely, people can reduce contact with some of the most harmful and common toxins to prevent harmful consequences on fetal development, a critical window of human development. Initiatives like Project TENDR, Toxic Matters and SafetyNest, offer practical recommendations to prevent exposure. Photo credit: iStock
