Microplastics in Human Bronchoalveolar Lavage Fluid.

ABSTRACT:

Background and objective

Health impacts of inhaling airborne microplastics have been actively investigated. Although microplastics have been detected in lung tissues and bronchoalveolar lavage fluids, their detection requires substantial effort and is technically challenging, with existing studies demonstrating various limitations. Bronchoalveolar lavage fluid is a less invasive sampling method than surgical lung biopsy. This study aimed to establish a detection method for microplastics from bronchoalveolar lavage fluid and evaluate the relevant health impacts.

Methods

Patients undergoing bronchoscopy for diffuse lung disease diagnosis were included. Microplastics were detected using Nile Red staining and fluorescence microscopy. Particle size, shape, and concentration were
