A team of US researchers has analyzed 62 human cales or placenta using gas chromatography and mass spectrometry, demonstrating that in all samples there were microplá sticos.El study was published by the journal Toxicological Sciences. According to him, the concentration of microplastics from one ka to another varies greatly, but in all of them a synthetic polymer was found.

The most common and abundant plastic found was polyethylene, which, in addition to 54% of the plastics found, was found in all samples. Polyvinyl chloride and nylon (10% each) are followed, while the remaining 26% are followed by 9 other polymers.

Researchers conclude that the method used is appropriate for the identification and quantification of microplastics in this type of tissue and hope it is useful for the study of toxicological risk.

In previous research, microplastics have also been found in other human samples, such as blood, intestine, and have been shown to be harmful to living things.
