UNAM undergraduate study detects 5-micron microplastics in Ciudad Universitaria air

An ongoing study by an Earth Sciences undergraduate at UNAM, the National Autonomous University of Mexico, reports pellet-type microplastics of about 5 microns in the air at Ciudad Universitaria.

Why it matters: People breathing the air at UNAM's Ciudad Universitaria are directly concerned, as the study reports particles there that can enter the human body.

According to Gaceta UNAM, a study now under way has found pellet-type microplastics measuring roughly 5 microns in the air at Ciudad Universitaria.

Gaceta UNAM reports that particles of this kind are able to enter the human body.

The research is being carried out by Jimena Martínez Nicolás, an undergraduate in the Earth Sciences degree programme (ENCiT).

Gaceta UNAM states that the possible effects of the microplastics and their origin will be investigated.

Editor’s view

Scott James, Research and Innovation Editor

The study concerns the air at Ciudad Universitaria, where Gaceta UNAM reports particles able to enter the human body; the next step it describes is an investigation into their possible effects and origin.

What to watch

  • Further investigation into the possible effects and origin of the airborne microplastics at Ciudad Universitaria.
