Microplastics Revealed in the Placentas of Unborn Babies

Health impact is unknown but scientists say particles may cause long-term damage to foetuses

icroplastic particles have been revealed in the placentas of unborn babies for the first time, which the researchers said was “a matter of great concern”.

The health impact of microplastics in the body is as yet unknown. But the scientists said they could carry chemicals that could cause long-term damage or upset the foetus’s developing immune system. The particles are likely to have been consumed or breathed in by the mothers.

The particles were found in the placentas from four healthy women who had normal pregnancies and births. Microplastics were detected on both the foetal and maternal sides of the placenta and in the membrane within which the foetus develops.

A dozen plastic particles were found. Only about 4% of each placenta was analysed, however, suggesting the total number of microplastics was much higher. All the particles analysed were plastics that had been dyed blue, red, orange or pink and may have originally come from packaging, paints or cosmetics and personal care products.

The microplastics were mostly 10 microns in size (0.01mm), meaning they are small enough to be carried in the bloodstream. The particles may have entered the babies’ bodies, but the researchers were unable to assess this.

“It is like having a cyborg baby: no longer composed only of human cells, but a mixture of biological and inorganic entities,” said Antonio Ragusa, director of obstetrics and gynaecology at the San Giovanni Calibita Fatebenefratelli hospital in Rome, and who led the study. “The mothers were shocked.”

In the study, published in the journal Environment International, the researchers concluded: “Due to the crucial role of placenta in supporting the foetus’s development and in acting as an interface with the external environment, the presence of potentially harmful plastic particles is a matter of great concern. Further studies need to be performed to assess if the presence of microplastics may trigger immune responses or may lead to the release of toxic contaminants, resulting in harm.”

The potential effects of microplastics on foetuses include reduced foetal growth, they said. The particles were not found in placentas from two other women in the study, which may be the result of different physiology, diet or lifestyle, the scientists said.

Microplastics pollution has reached every part of the planet, from the summit of Mount Everest to the deepest oceans. People are already known to consume the tiny particles via food and water, and to breathe them in.

Their effect in the body is unknown but scientists say there is an urgent need to assess the issue, particularly for infants. In October, scientists revealed that babies fed formula milk in plastic bottles are swallowing millions of particles a day. In 2019, researchers reported the discovery of air pollution particles on the foetal side of placentas, indicating that unborn babies are also exposed to the dirty air produced by motor traffic and fossil fuel burning.

The Italian researchers used a plastic-free protocol to deliver the babies in order to prevent any contamination of the placentas. Obstetricians and midwives used cotton gloves to assist the women in labour and only cotton towels were used in the delivery room.

Andrew Shennan, professor of obstetrics at King’s College London, told the Daily Mail it was reassuring that the babies in the study had normal births but “it is obviously preferable not to have foreign bodies while the baby is developing”.

Elizabeth Salter Green, at the chemicals charity Chem Trust, said: “Babies are being born pre-polluted. The study was very small but nevertheless flags a very worrying concern.”

A separate recent study showed that nanoparticles of plastic inhaled by pregnant laboratory rats were detected in the liver, lungs, heart, kidney, and brain of their foetuses. your social media marketing partner
