Measurement of Microplastic Release After the Use of Polypropylene Nasal Irrigation Bottles.

ABSTRACT:

Objectives

Microplastics originating from plastic materials may pose risks to human health. This study investigated the presence of microplastics in nasal irrigation fluids collected from reused bottles, focusing on the duration of bottle usage.

Methods

Readily available nasal irrigation bottles made of polypropylene were purchased. Unused bottles served as controls. Test samples were prepared to simulate 1-, 3-, and 6-month reuse. Nasal irrigation fluid samples (n=12) were collected from each set of bottles: three from the new control bottles and nine from the bottles simulating 1-, 3-, and 6-month reuse. Raman spectroscopy was used to detect microplastics in the nasal irrigation samples, and the results were compared based on the duration of bottle use.
