Summary

Researchers detected microplastics in nasal irrigation fluids from polypropylene irrigation bottles after simulated use, with significantly higher microplastic counts in fluids from bottles representing 3 months of use compared to controls. The findings indicate that repeated mechanical stress on polypropylene nasal irrigation bottles releases microplastics directly into the nasal cavity during use.

Polymers

We detected microplastics in nasal irrigation fluids, which likely originated from the repeated use of nasal irrigation bottles. The quantity of microplastics was significantly higher in samples from bottles simulating 3 months of use compared to the control samples. Therefore, we recommend the development of guidelines to regulate the duration of nasal irrigation bottle usage to reduce microplastic infiltration into the body via the sinonasal cavity.
