Nanoplastics in the Human Respiratory System
Summary
This research paper reports on the detection and characterization of nanoplastics in the human respiratory system, published in a leading pulmonary medicine journal. The study adds to growing evidence that extremely small plastic particles are present in human lungs. The findings underscore the importance of understanding inhalation as a key route of human exposure to plastic pollution.

Presence of microplastics in human’s respiratory system: bronchoalveolar and bronchial lavage fluid
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.
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.
Micro- and Nanoplastics and Pulmonary Health: The Current State of Research
This review evaluates the effects of micro- and nanoplastics on the respiratory system, noting that human autopsy studies confirm these particles are retained in lung tissue. Researchers examined how inhaled plastic particles may induce respiratory inflammation, oxidative stress, and other pulmonary effects. The study highlights that while airborne microplastics are a growing concern, our understanding of their short- and long-term impacts on lung health remains limited.
The Effect of Nanoplastics and Microplastics on Lung Morphology and Physiology: a Systematic Review
This systematic review examines how inhaled microplastics and nanoplastics affect lung structure and function. The research found that indoor microplastic concentrations are often higher than outdoor levels due to household materials shedding fibers, and that inhaled particles can accumulate in different parts of the lungs. These findings suggest that breathing in plastic particles at home and work could contribute to respiratory health problems over time.
Deleterious effects of microplastics and nanoplastics on rodent lungs: a systematic review
This systematic review summarizes research on how inhaled micro- and nanoplastics affect the lungs in animal studies. The findings show these particles can cause lung inflammation, tissue damage, and immune responses, suggesting that breathing in airborne microplastics may pose real risks to respiratory health.
