Are you considering starting a family, already pregnant, or have you just had a new baby? If you have questions or concerns about shooting while pregnant, or other issues associated with firearms prior, during or after pregnancy, keep reading!
In this first of a 3-part series, we’ll take a closer look at shooting issues to consider before you become pregnant.
Two of the most common risks that are mentioned in conjunction with shooting and pregnancy are heavy metals (lead and mercury) and noise levels. In this first installment, I’ll be discussing lead and other chemical hazards; the next segment will dive into the topic of noise and when fetal sound development begins.
An extensive body of research shows that lead exposure is harmful to fetuses. Lead crosses the placenta and is transmitted from the mother to the fetus . Lead exposure during pregnancy has been associated with serious complications, including spontaneous abortion, premature membrane rupture, preeclampsia, pregnancy hypertension  and neurobehavioral effects in infants and children . Even at low levels, lead exposure has been associated with preterm delivery; congenital abnormalities ; and decreased birth weight, length and head circumference .
In her report, “Shooting While Pregnant,” Julie Golob writes, “The CDC warns how ‘lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. Lead can damage a developing baby’s nervous system. Even low-level lead exposures in developing babies have been found to affect behavior and intelligence. Lead exposure can cause miscarriage, stillbirths, and infertility.’” Read the rest of the article.
