ClearAirborne Microplastics: Another Threatening to Our Health
This review examines the emerging evidence on airborne microplastics, covering their sources, how they travel through the atmosphere, and how they enter the human respiratory system through inhalation. Researchers highlight potential health effects including pulmonary inflammation, oxidative stress, and endocrine disruption, with particle size influencing how deeply they penetrate into the lungs. The study calls for standardized measurement protocols and urgent interdisciplinary research to better understand the health risks of breathing in microplastic particles.

The study calls for standardized protocols to enable meaningful comparisons and more accurate assessment of the health risks posed by airborne microplastics.
Status and prospects of atmospheric microplastics: A review of methods, occurrence, composition, source and health risks
This review summarized the sampling methods, occurrence, composition, sources, and health risks of atmospheric microplastics. Researchers found that airborne microplastics are detected both indoors and outdoors, with fibers being the most common shape, and that inhalation represents an important but understudied exposure pathway. The study suggests that atmospheric transport plays a significant role in the global distribution of microplastic pollution.
Microplastics in the Air
This book chapter examines atmospheric microplastic pollution, reviewing the presence of MPs in outdoor and indoor air, the mechanisms by which they become airborne, human inhalation exposure estimates, and evidence for respiratory health effects.
A comprehensive review of micro- and nano-plastics in the atmosphere: Occurrence, fate, toxicity, and strategies for risk reduction.
This review examines a decade of research on micro- and nano-plastics (MNPs) in the atmosphere, covering their occurrence in outdoor and indoor air, toxicological effects on human health, and strategies to reduce exposure risk from inhalation of airborne plastic particles.
Microplastics in the atmosphere: a review
This review assessed the current state of knowledge on microplastics in the atmosphere, finding that airborne plastic particles have been detected in both indoor and outdoor environments across multiple regions worldwide. Researchers noted that comparing results across studies is difficult because sampling methods and reporting standards vary widely. The study calls for harmonized measurement approaches so that atmospheric microplastic data can be reliably used for human health risk assessments.
Atmospheric micro (nano) plastics: future growing concerns for human health
This review examines the growing concern about nanoplastics in the atmosphere and their potential effects on human health, an area that has received far less attention than microplastics in water or soil. Researchers found that airborne nanoplastics can penetrate deep into the lungs and potentially enter the bloodstream due to their extremely small size. The study identifies critical knowledge gaps and calls for more research on inhalation exposure pathways and long-term health consequences.
Potential Effects of Environmental and Occupational Exposure to Microplastics: An Overview of Air Contamination
This review summarizes what is known about airborne microplastics in both general and workplace environments, noting that indoor concentrations often exceed outdoor levels. While the WHO has called for more research on health effects, toxicity studies remain limited and not easily comparable due to a lack of standardized methods -- meaning the full health risks of breathing in microplastics are still unclear.
