Detection of microplastics in patients with allergic rhinitis
In a study of 66 patients, researchers found significantly more microplastic particles in nasal wash samples from people with allergic rhinitis compared to healthy volunteers. The microplastics found were mostly fibers and fragments small enough to deposit in nasal passages during normal breathing. This is among the first studies to link airborne microplastic exposure in the nose to an allergic condition, suggesting inhaled microplastics may contribute to nasal inflammation.
