The findings show that nanoscale polystyrene plastics ingested by pregnant mammals can penetrate the intestinal barrier, cross the maternal-fetal barrier of the placenta, and reach all fetal tissues.plastic particles, similar to those commonly found in food and water, can transfer from pregnant rats to their fetuses and potentially impact fetal development. The study suggests that this process may also occur in humans.
Erosion causes microscopic plastic particles to break away from the billions of tons of plastics in the environment that are exposed to the elements. These particles mix with our food and air, with an average person ingesting the equivalent amount as a credit card each week, according to Demokritou. The study provided specially marked nanoscale plastics to five pregnant rats. Subsequent imaging found that these nanoplastic particles permeated not only their placentas but also the livers, kidneys, hearts, lungs, and brains of their offspring.plastics can breach the intestinal barrier of pregnant mammals, the maternal-fetal barrier of the placenta, and all fetal tissues.
“Petroleum-based plastics are not biodegradable, but weathering and photooxidation break them into tiny fragments. These tiny fragments, called micro-nano-plastics, are found in human lungs, placentas, and blood, raising human health concerns. As public health researchers, we are trying to assess the health risks from such an emerging contaminant to inform policymakers and develop mitigation strategies.
