Nasal irrigation fluid samples (n=12) were collected from each set of irrigation bottles: three from new control bottles and nine from bottles mimicking 1-, 3-, and 6-month reuse. Raman spectroscopy was employed to detect microplastics in the nasal irrigation samples; the results were compared according to the bottle use duration.ResultsAn average of 33.00±20.42 (ea/300 mL) microplastic particles was detected in the nasal irrigation fluid from the control bottles relative to an average of 68.66±30.07, 261.66±20.59, and 204.33±52.16 (ea/300 mL) from bottles used for 1, 3, and 6 months, respectively.
