A new study presented yesterday at the American Chemical Society (ACS) Fall 2020 Virtual Meeting has found microplastics inside human organs for the first time
However, very little is known about the health effects on human tissues.
“At this point, we don’t know whether this plastic is just a nuisance or whether it represents a human health hazard,” said Rolsky.and they do at least pass through the digestive system, as evidenced by the finding that they were widely found in fecal samples from people all over the world. However, very little is known about whether they go elsewhere in the body after ingestion or what health effects they have, if any, on humans.
To look at this, Rolsky and colleagues accessed human tissue samples from a large repository which was set up to study neurodegenerative conditions such as Alzheimer’s disease. They looked at 47 samples taken from organs likely to be exposed to or filter microplastics; the lungs, liver, spleen and kidneys and found evidence of plastics in every single sample.
They extracted he plastics from the samples and analyzed them by a method called μ-Raman spectrometry, then using a computer algorithm to calculate the exact amount and type of plastics found.
