Pharmaceutical Reviews (Associate Editor) About 16.2 particles of microplastic could be inhaled by people per hour, which is the same as one credit card over the course of a week. Additionally, these microplastics tiny environmental waste produced by the breakdown of plastic products often include hazardous contaminants and poisons. Understanding how inhaled microplastics move through the respiratory system is crucial for both preventing and treating respiratory disorders since it can lead to major health hazards. To study microplastic transport and deposition in the upper airway, researchers from the University of Technology Sydney, Western Sydney University, Urmia University, Islamic Azad University, the University of Comilla, and Queensland University of Technology created a computational fluid dynamics model.
“Millions of tons of these tiny pieces of plastic have been discovered in the soil, air, and water. The density of microplastics in the air is dramatically rising, and global microplastic output is booming. Microplastics were discovered in human airways for the first time in 2022, raising concerns about serious risks to respiratory health.
