Plasticenta: Microplastics in Human Placenta
AI summary Read the abstract
This study analyzed six human placentas using Raman microspectroscopy and found colored microplastic particles in all samples, providing direct evidence that microplastics can cross the placental barrier and reach fetal tissue. This groundbreaking finding demonstrates that unborn babies are exposed to microplastics before birth, raising urgent questions about potential developmental impacts.
Summary paragraph Microplastics are particles smaller than five millimetres obtained from the degradation of plastic objects abandoned in the environment. Microplastics can move from the environment to living organisms and, in fact, they have been found in fishes and mammals. Six human placentas, prospectively collected from consenting women with uneventful pregnancies, were analyzed by Raman Microspectroscopy to evaluate the presence of microparticles. Detected microparticles were characterized in terms of morphology and chemical composition. 12 microparticles, ranging from 5 to 10 μm in size, were found in 4 out of 6 placentas: 5 in the foetal side, 4 in the maternal side and 3 in the chorioamniotic membranes. All the analyzed microparticles were pigmented: three of them were identified as stained polypropylene, while for the other nine it was possible to identify only the pigments, which are all used for man-made coatings, paints and dyes. Here we show, for the first time, the presence of microparticles and microplastics in human placenta. This sheds new light on the impact of plastic on human health. Microparticles and microplastics in the placenta, together with the endocrine disruptors transported by them, could have long-term effects on human health.

Plasticenta: First evidence of microplastics in human placenta
AI summary Read the abstract
In a landmark study, researchers detected microplastics in human placental tissue for the first time, finding 12 plastic fragments in placentas from four out of six women with healthy pregnancies. The particles were identified as polypropylene and dyed plastics likely from packaging or cosmetics, raising concerns about potential effects on fetal development and pregnancy.
Raman-guided exploration of placental microplastic exposure: Unraveling the polymeric tapestry and assessing developmental implications
AI summary Read the abstract
Scientists examined placentas from 50 women after delivery and found microplastics in 62% of them, with seven different plastic types identified including Teflon (PTFE), polystyrene, and ABS. While the particles did not appear to affect birth weight, length, or gestational age in this study, their widespread presence in placental tissue confirms that plastic pollution reaches developing babies before birth. More research is needed to understand potential long-term effects.
Quantitation and identification of microplastics accumulation in human placental specimens using pyrolysis gas chromatography mass spectrometry
AI summary Read the abstract
Researchers analyzed 62 human placenta samples and found microplastics in every single one, with concentrations ranging from 6.5 to 685 micrograms per gram of tissue. Polyethylene, the most common plastic in everyday products, made up 54% of the plastics found. This widespread presence of microplastics in placentas raises concerns about fetal exposure during pregnancy and potential effects on development.

Deeply in Plasticenta: Presence of Microplastics in the Intracellular Compartment of Human Placentas
AI summary Read the abstract
Researchers analyzed human placenta samples and for the first time located microplastics within the intracellular compartment of placental tissue, not just on the surface. They found various polymer types including polyethylene and polypropylene embedded inside placental cells. The discovery that microplastics penetrate into the interior of human cells raises new questions about their potential biological effects during pregnancy.
