Summary
This preliminary study found microplastics — primarily polypropylene from the nozzle of the irrigation device itself — in nasal rinse fluids used for sinus irrigation. The discovery raises questions about whether routine nasal irrigation could be inadvertently delivering plastic particles directly into the nasal passages and potentially deeper into the respiratory tract. The authors call for further research to understand the health significance of this previously unrecognized exposure route.
Microplastics were identified in nasal irrigations Polypropylenes, which were the main component of the nozzle, were commonly identified Additional studies are needed to understand the biological relevance of microplastics in nasal irrigations.
