A new study by US researchers has uncovered that babies born prematurely have higher levels of microplastics in their placentas compared to full-term babies. The study analyzed 100 placentas from full-term births (37.2 weeks) and 75 from preterm births (34 weeks) in the Houston area. The results revealed that preterm placentas contained 203 micrograms of plastic per gram of tissue, a level more than 50% higher than the 130 micrograms found in full-term placentas.
Link Between Microplastics and Preterm Births: A Growing Health Concern
The researchers identified at least 12 types of plastics in the placentas, with PET (commonly used in bottles), PVC, polyurethane, and polycarbonate being the most prevalent in those from preterm births. Kjersti Aagaard, a maternal-fetal specialist, suggested that the accumulation of these plastics might contribute to the risk of preterm births. She highlighted the increasing body of evidence that links plastic exposure to a range of health issues, such as heart disease and stroke.
The study also indicated that although factors such as age, ethnicity, and socioeconomic status can raise the likelihood of preterm birth, the link between microplastic presence and preterm birth remained strong even after accounting for these variables.
Microplastics: A Global Contamination Crisis Threatening Human Health
Microplastics, tiny plastic particles smaller than five millimeters, have been found in diverse environments, from the Mariana Trench to Mount Everest. They have also been detected in human bodies, including in semen, breast milk, brains, and organs, underscoring the extent of contamination. The first discovery of microplastics in placentas in 2020 raised concerns about their potential impact on human health. Scientists are now urging immediate action, warning that microplastic pollution poses a serious threat to all life on Earth.
Summary:
A study found that preterm babies accumulate more microplastics in their placentas than full-term babies. Researchers identified 12 types of plastic, with PET and PVC being most common. Despite factors like age and socioeconomic status, the link between microplastics and preterm birth remained strong, raising concerns about their broader health impacts.
