Study Finds Black Carbon Travels To Pregnant Women’s Placenta

According to a new study, when pregnant women breath in black carbon, tiny particles from the soot travels from her lungs to the placenta. Black carbon, which comes from cars and burning wood, can cause inflammation and has been found in fetuses as young as 12 weeks.

Scientists analyzed 20 pregnant women in Belgium and found black carbon in every placenta. A similar study last year of Boston-area moms found when fetuses were exposed to black carbon in the third trimester, there was a higher likelihood of kids having high blood pressure. Premature and low birth weight has been linked with bad air quality and has also been connected with an increase in infant mortality.

Vox has more on the results of this study, which is a first of its kind due to the evidence of black carbon reaching the placenta.
