Microplastics are tiny particles of plastic, usually less than 5 millimeters in size. The study is published in the journal Physics of Fluids. “This study emphasizes the need for greater awareness of the presence and potential health impacts of microplastics in the air we breathe,” concluded co-author YuanTong Gu, a professor of Mechanical, Medical, and Process Engineering at the Queensland University of Technology. This will be done in order to help inform the development of targeted drug delivery devices and improve health risk assessment. This includes environmental parameters such as temperature and humidity. In future research, the scientists plan to investigate microplastic transport in a large-scale, patient-specific whole lung model. These findings highlight the dangers of exposure to and inhalation of microplastics, especially in regions with high levels of plastic pollution and industrial activity. Further research is needed on inhaled microplastics For instance, a higher flow rate led to less deposition, and the largest microplastics were deposited in the airways more frequently than the smaller ones. The flow speed, particle inertia, and asymmetric anatomy influence the overall deposition and increase the deposition concentration in nasal cavities and the oropharynx area,” Islam explained.īoth breathing conditions and microplastic size played significant roles in the overall microplastic deposition rate in airways. “The complicated and highly asymmetric anatomical shape of the airway and complex flow behavior in the nasal cavity and oropharynx causes the microplastics to deviate from the flow pathline and deposit in those areas. The analysis revealed that inhaled microplastics tended to collect in several areas of the nasal cavity and oropharynx, or back of the throat. What the researchers discovered about inhaled microplastics To prevent and treat respiratory diseases caused by inhaled microplastics, understanding how they travel in the respiratory system is crucial.īy developing a computational fluid dynamics model, the experts analyzed the transport and deposition of microplastics with different shapes (spherical, tetrahedral, and cylindrical) and sizes (1.6, 2.56, and 5.56 microns) in the upper airways, under both slow and fast breathing conditions. “For the first time, in 2022, studies found microplastics deep in human airways, which raises the concern of serious respiratory health hazards.” How the microplastics research was conducted He is an expert in Materials and Process Engineering at UTS. Global microplastic production is surging, and the density of microplastics in the air is increasing significantly,” said lead author Mohammad S. “Millions of tons of these microplastic particles have been found in water, air, and soil.
