What health risk is particularly heightened for pregnant women due to lead exposure?

Lead exposure poses significant health risks to pregnant women, most notably the risk of miscarriage and developmental issues in the fetus. When a pregnant woman is exposed to lead, the toxic metal can cross the placenta and affect the developing fetus. This exposure has been linked to a higher chance of miscarriage, preterm birth, low birth weight, and can cause long-term developmental problems for the child, including cognitive impairments and behavioral issues.

The other choices, while they may pose risks to pregnant women, are not directly associated with lead exposure. Increased cholesterol levels, gestational diabetes, and hypertension can occur during pregnancy due to a variety of factors, but they are not primarily connected to lead toxicity in the same way that miscarriage and developmental issues are. Understanding the specific dangers of lead exposure is crucial for ensuring the health of both the mother and the unborn child.
