A new study finds that microplastics and nanoplastics accumulate at higher levels in the brain than in the liver and kidney.

A confocal light micrograph showing blood vessels in a three-year-old zebrafish (magenta: endothelial cells of blood vessels; green: endothelial cell nuclei). RIKEN researchers have shown that ...

Microscopic – walls are one cell thick ... The structure of the blood vessels can be easily compared when they are seen in this cross-section (not to scale).

“Nanoscale plastics can breach the blood-brain barrier, [but] how [microplastics] cause brain functional irregularities remains unclear,” wrote the study’s authors.

Inside you, there is an amazing network of blood vessels, the tubes that carry blood all around your body. Every part of the body needs oxygen, food and water. The blood vessels are a bit like ...
