New research shows evidence of soot from polluted air in placentas

Previous studies have found that toxic air affects unborn babies but were unable to find evidence as to how the damage is specifically done.

She added that particles do not need to get into the baby's body in order to be harmful because simply affecting the placenta directly impacts the foetus.

They looked very like the sooty particles found in macrophages in the lung, which catch many - but not all - of the particles. Studies have linked polluted air to many a health problem, including premature birth, low birth weight, and infant mortality as well as childhood obesity, high blood pressure, respiratory problems, and brain abnormalities.

The findings suggest pregnant women living in polluted cities like London are particularly at risk of passing on toxins from traffic pollution to their unborn child.

On examining the particles using powerful electron microscope, the researchers found that they resemble sooty particles found in macrophages in the lung. After their babies were born, the researchers examined the placenta.

New research involving potential mothers in the United Kingdom indicates that toxic air directly affects pregnant women and their fetuses, with evidence showing that particles travel to their placentas.

The samples were from five pregnant women, all non-smokers, who lived in London and underwent planned caesareans.

The scientists had made a decision to look at macrophages in other organs (other than lung) with an anticipation of finding direct evidence of inhaled particles moving out of the lungs to other parts of the body.

In previous research, the team used the same techniques to identify and measure these sooty particles in people's airways.

"This should raise awareness amongst clinicians and the public regarding the harmful effects of air pollution in pregnant women".

The overview is being presented Sunday at the European Respiratory Society's (ERS) world congress in Paris. Liu also said that while the study does not prove that the particles they found can (or will) move through the placenta to the fetus, it's certainly possible - and even if they can't, they still have an adverse effect via the placenta, which connects the mother to the fetus. The researchers isolated macrophage cells, which are a part of the physique's immune map and engulf nasty particles similar to bacteria and air air pollution.

Miyashita and Lue's findings were presented Sunday in Paris at the European Respiratory Society's worldwide congress, to raise awareness about air pollutions harmful effects. In total, they singled out 60 cells with 72 small black areas across the five placentas. On average, each placenta contained around five square micrometres of this substance. For that reason alone, Professor Mina Gaga, the President of the European Respiratory Society, said of the study: "This new research suggests a possible mechanism of how babies are affected by pollution while being theoretically protected in the womb".

Do you think we need stricter air pollution policies?

A series of old overview personal proven that air air pollution very a lot will increase the risk of untimely birth and of low birth weight, ensuing in lifelong injury to effectively being.
