Ooooh, hello dear English speaking-reading-hearing reader, welcome back to me, @sciencemug, the blog/podcast/twitter&instagram accounts/entity behind the unsuccessful e-shop stuffngo on zazzle.com which tells you science stories while reading the palm but yet not being able to decipher the tree, aaand which talks to you thanks to the voice, kidnapped via a voodoo-wireless trick, from a veeery very very dumb human.
Aaand which does all of this in English-question-mark, a language that is to proper English what a banana bacon muffin is to something that doesn’t scream: “human civilization is doomed!”.
Today I’m gonna tell you the second part (the first one is here) of a story about human placentas and plastics!

A group of Italian researchers (aka the Italian Brains, aka the ITBs) studies human placentas in search of microplastics fragments (MPs), that is plastic particles smaller than half a centimeter. In doing so, the researchers find such pollutants in the placentas of women in good health and who have had normal pregnancies and deliveries. The ITBs’ study is therefore “the first [one] revealing the presence of [...] microplastics and, in general, of man-made particles in human placenta” (P).
The Italian research team is lead by Medical Doctor Antonio Ragusa, Head of the Department of Woman, Mother and Newborn of the San Giovanni Calibíta Fatebenefratelli Hospital, in Rome, and it publishes its study (P) in the science journal Environment International.
Sooo, dear reader, in part 1 I told you about the microplastics classification story, and also about how the Italian Brains select the women involved in their study, how they design and follow a plastic free protocol to collect the placenta samples, and what kind of technique (the Raman microspectroscopy) they use to analyze such samples.
Now, all in all, the ITBs collect six placentas. Let’s remember that, from each placenta, the ITBs take and then analyze, precisely via Raman microspectroscopy, three pieces between about 20 and 30 gr of weight (the mean weight is 23.3gr). Of these three pieces, one comes from the maternal side of the placenta, one from the fetal side, and the third one from the chorioamniotic membranes, namely the two membranes that form the embryo sac, which is the structure that surrounds and protects the fetus.
Sooo, dear reader, let’s see then what the ITBs find out.
of the 6
collected placentas the researchers find a total of 12 small
fragments of non-human something.

How small, you ask?
Well, ten fragments are about 10μm in size, while
