Air pollution can reach the womb, as the study showed. Scientists have discovered particles of toxic soot inside the placenta, which got there due to the air that is inhaled pregnant.
Soot and the soot from the exhaust of vehicles can combine with air to penetrate the uterus of pregnant and thereby affect the health of future children, the study showed scientists from Queen Mary University in London. Science long ago figured out that tiny particles of these toxic substances can cause underweight baby, increase the risk of mortality, and also affect the development of respiratory problems in the future like asthma. Now, however, the study showed the ability of these substances to penetrate the placenta. And this increases the likelihood that soot and the soot gets to the fetus.
The authors of the study observed in 5 moms-to-be living in London who were prepared to hold the scheduled caesarean sections. These women did not smoke, their pregnancy was without complications, and each gave birth to one healthy baby. Experts interested in the placenta shortly after birth, and especially the cells called placental macrophages. It is part of the immune system that resists the harmful particles like bacteria and toxins from contaminated air. In General, the researchers studied more than 3,500 placental macrophages and had a very powerful microscope.
It was found that 60 cells together contained 72 small black area. The researchers believe that it was carbon particles. On average, each placenta had 5 square micrometers of these substances. The results of observations gave the first evidence that inhalation of contaminated particles facilitates their movement from the lungs to the circulatory system, and thence into the placenta. It is unknown whether these particles also penetrate into the body of a child, but everything points to the fact that it is possible. (READ MORE)
