A study has found that precise pollution and nanoparticles are much higher in the placenta of early births than those in full -term births.
The levels were much higher than previously discovered in the blood, indicating that small plastic molecules accumulate in the placenta. But the middle higher levels in the shorter pregnancy were a “big surprise” for researchers, as it is expected to lead to more accumulation.
Childbirth prematurely The main cause of the death of infants Dr. Enrico Parroso of the College of Medicine Baylor in Texas, the United States, said the reasons that were conducted all over the world, and the reasons for about two -thirds of all births prematurely were not known. The fixed link between Air pollution and millions of early births The research team motivated to investigate plastic pollution.
The new study only shows a relationship between precise plastic and early births. More research in cellular cultures and animal models is needed to determine whether the link is causal. It is known that accurate plastic causes inflammation in human cells, and inflammation is one of the factors that push the start of work.
Methodic plastic, Menax from plastic waste, the entire planet from The summit of Mount Everest to Deepest oceans. It is known that people consume small particles Through foodand water and Breathe.
It was strict plastic It was first discovered in the placenta in 2020 It has also been found in semenand Breast milkand Minds, liver and bone marrowReferring to heavy pollution of people’s bodies. Impact on human health is unknown, but the exact plastic was Concerned with strokes and heart attacks.
“Our study indicates the possibility that the accumulation of plastic can contribute to premature birth,” said Professor Kjersti Aagaard at Boston Children’s Hospital in the United States. “Along with other recent research, this study adds to a growing set of evidence that illustrates a real danger of plastic exposure to human health and disease.”
the research It was presented on Thursday at the annual meeting of the Association of Mothers Medicine in Denver, and was presented to an academic magazine. The researchers analyzed 100 of the placenta of full -term births (37.2 weeks, average) and 75 early births (34 weeks), all from Houston.
The analysis with a highly sensitive mass is found 203 micrograms of plastic per gram of tissue (microgram/grams) in the early placenta-more than 50 % of 130 micrograms/grams in the full-term placenta.
Twelve types of plastic have been discovered, with great differences between the placenta full birth and the dove of pets, as is used in plastic bottles, PVC, polyurethane and polycarbonate.
Some mothers are at greater risk of birth prematurely, because of their age, race, social and economic situation. But a strong link between the plastic particles and premature birth remained even when these factors were taken into account.
“This study showed a link, not causal,” Paruzo said. “But I think it is important to increase people’s awareness of strict plastic and their connections with the effects of the potential human health.”
He said that the effectiveness of procedures to reduce people’s exposure to exact plastic also needs an urgent study. “These interventions must be studied to show that there is benefit to avoid this plastic.”
