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.
Breathing plastics: Influence of airborne microplastics on the respiratory microbiome and health of human lungs (Review)
Researchers reviewed evidence showing that inhaled airborne microplastics can physically interact with the microbial community living in human lungs, disrupting its balance and triggering inflammation linked to conditions like asthma and fibrosis. Because microplastic particles have been found in lung tissue and fluid samples, inhalation is now recognized as a significant exposure route with measurable consequences for respiratory health.
Microplastics exposed by respiratory tract and exacerbation of community-acquired pneumonia: The potential influences of respiratory microbiota and inflammatory factors
Researchers found that microplastics were present in the lungs of pneumonia patients, and that patients with severe pneumonia had higher levels of microplastics in their airways than those with milder cases. The microplastics appeared to worsen lung infections by disrupting the balance of airway bacteria and increasing inflammation. This study provides early evidence that inhaled microplastics may make respiratory infections more dangerous in humans.
Presence of airborne microplastics in human lung tissue
Researchers examined human lung tissue from autopsies and found microplastic particles and fibers in 13 out of 20 samples. The most common plastics were polyethylene and polypropylene, with particles smaller than 5.5 micrometers. This study provides direct evidence that inhaled microplastics accumulate in human lungs, raising concerns about potential long-term effects on respiratory health.

This review summarized the respiratory toxicity of airborne microplastics, covering their sources, the routes by which they penetrate deep into lung tissue, and the range of clinical outcomes from chronic inflammation to potential malignancy. The authors warn that inhalation exposure represents an underappreciated and growing public health threat.
Airborne microplastics: Consequences to human health?
Researchers reviewed existing evidence on airborne microplastics and their potential effects on human respiratory health. Studies of workers exposed to plastic fibers and particles have documented airway inflammation and breathing difficulties, suggesting that susceptible individuals may face health risks even from environmental concentrations. The paper calls for greater awareness and future research into the health consequences of inhaling microplastic particles.
New evidence of the presence of micro- and nanoplastic particles in bronchioalveolar lavage samples of clinical trial subjects
Researchers found micro- and nanoplastic particles in the lung fluid of patients undergoing bronchoscopy — a procedure that samples the deep airways — marking the first detection of airborne nanoplastics in the lower respiratory tract of living humans. All samples contained plastic particles, confirming that people in Northern Europe are regularly inhaling plastics, though the health effects remain under investigation.
Airborne microplastics: A narrative review of potential effects on the human respiratory system
This review consolidates research on airborne microplastics and their potential effects on the human respiratory system. Studies show that inhaled microplastics can deposit in the lungs, trigger inflammation, cause oxidative stress, and lead to cell damage and death. While human exposure evidence is still limited, animal and cell studies suggest that long-term inhalation of airborne microplastics could pose significant risks to lung health.
Detection and Analysis of Microplastics in Human Sputum
Researchers analyzed sputum (mucus from the lungs) from 22 patients with respiratory diseases and found microplastics in every single sample, identifying 21 different plastic types. Polyurethane was the most common type detected, and most particles were smaller than 500 micrometers. This study provides direct evidence that humans are inhaling microplastics, with factors like smoking and medical procedures increasing the amount found in the respiratory tract.

First evidence of microplastics isolated in European citizens’ lower airway
Researchers provided the first evidence of microplastics in the lower airways of living European adults, using bronchoalveolar lavage fluid from 44 patients. Nearly all detected particles were microfibers averaging about 1.7 millimeters in length, with an average concentration of roughly 9 items per 100 milliliters of fluid. The findings confirm that microplastics reach deep into the human respiratory system, though the health implications require further investigation.
A systematic review of the effects of airborne microplastic contamination on human lungs
This systematic review summarizes research showing that airborne microplastics have a negative effect on human lungs. Humans are estimated to inhale roughly 100,000 fine plastic particles every day, and the evidence suggests this exposure contributes to respiratory health problems, underscoring the need for policies to reduce plastic pollution in the air we breathe.
Microplastics in urine, sputum and lung lavage fluid from patients with respiratory illnesses
Researchers analyzed urine, sputum (mucus from coughing), and lung fluid from 30 patients with respiratory conditions in Iran and found microplastics in all three types of samples. Sputum contained the most particles (358 total), dominated by polyurethane fibers, while urine had the fewest (9 particles). The different types and sizes of plastics found in each fluid suggest the body sorts and distributes inhaled and ingested microplastics through different pathways.
Human Responsive Biomarkers of Airborne Microplastics Exposure: Evaluation and Analysis for Health and Environment
This research review looked at 14 studies to understand how tiny plastic particles in the air affect human health by measuring specific markers in our blood and lungs. The studies found that breathing in microplastics causes inflammation in our airways and lungs, similar to what happens with asthma, by triggering the body's immune response. This matters because it helps scientists develop better ways to detect early health problems from plastic pollution and create guidelines to protect people from these invisible particles we breathe every day.

Isolation and characterization of microplastics from the human respiratory system: Sputum, broncho-alveolar lavage fluid, and pleural fluid simultaneously
In the first study of its kind in Iran, researchers found microplastics in every sample collected from the human respiratory system, including sputum, lung fluid, and the fluid surrounding the lungs. Polyester fibers were the most common type detected, and people with occupational exposure or smoking habits had higher amounts, confirming that we regularly breathe in microplastics that reach deep into our lungs.
Microplastics in the Bronchoalveolar Lavage Fluid of Chinese Children: Associations with Age, City Development, and Disease Features
Microplastics were detected in nearly 90% of lung fluid samples from Chinese children with respiratory diseases, with an average of about 4 particles per 10 milliliters. Younger children and those living in more developed urban areas had higher levels, likely due to more indoor crawling behavior and greater surrounding plastic use. This is significant because it confirms that children are inhaling microplastics into their lungs, and younger children may be especially vulnerable.
