Microplastics in Human Bronchoalveolar Lavage Fluid
AI summary Read the abstract
Researchers developed a new method for detecting microplastics in fluid washed from human lungs (bronchoalveolar lavage fluid) and found plastic particles present in every patient tested. They also applied Nile Red staining for the first time to visualize plastics in lung samples, which proved effective for screening and counting particles. The findings provide direct evidence that microplastics are present in the human respiratory system, with a potential link to lung inflammation.
We established a method for detecting microplastics in bronchoalveolar lavage fluid. Microplastics were found in all patients, with a potential link to inflammation. In addition, Nile Red staining was applied for the first time to detect plastics in the lung and appeared to be useful for screening and quantification.

Presence of microplastics in human’s respiratory system: bronchoalveolar and bronchial lavage fluid
AI summary Read the abstract
Researchers analyzed bronchial and bronchoalveolar lavage fluid from patients undergoing bronchoscopy and confirmed the presence of microplastics in the human respiratory system. They characterized the types, sizes, and quantities of microplastic particles found at different levels of the airways. The study provides direct evidence that microplastics deposit within human lungs and suggests that respiratory exposure is a meaningful route of human microplastic intake.

Microplastics in Human Bronchoalveolar Lavage Fluid
AI summary Read the abstract
Researchers developed a method to detect microplastics in bronchoalveolar lavage fluid, a less invasive sampling technique than surgical lung biopsy, to assess human respiratory exposure. Using fluorescence microscopy and Raman spectroscopy, they identified and characterized microplastic particles in lung wash samples from patients undergoing bronchoscopy. The study suggests that lavage fluid analysis could become a practical tool for monitoring microplastic exposure in human lungs.
