ClearRespiratory Toxicity of Microplastics: Mechanisms, Clinical Outcomes, and Future Threats
This review examined the mechanisms by which inhaled airborne microplastics cause respiratory harm, including inflammation, oxidative stress, fibrosis, and impaired mucociliary clearance. The authors also discuss emerging evidence linking microplastic inhalation to worsening asthma, COPD, and potentially lung cancer.
Airborne 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.
Airborne micro- and nanoplastics: emerging causes of respiratory diseases
This review examines growing evidence that tiny airborne plastic particles can enter the lungs and trigger or worsen respiratory diseases including asthma, chronic obstructive pulmonary disease, and lung inflammation. The smallest nanoplastics are especially concerning because they can penetrate deep into lung tissue and even enter the bloodstream, yet research on airborne plastic health effects significantly lags behind studies on waterborne exposure.
Airborne microplastics: a Trojan horse for respiratory dysfunction and multiorgan damage
This review examined evidence on airborne microplastics as a route of human exposure, focusing on how inhaled particles may affect respiratory function and potentially reach other organs. The study suggests that microplastics can act as carriers for other pollutants and pathogens, and that inhalation exposure warrants greater research attention alongside the more commonly studied ingestion pathway.
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.
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 and Nanoplastics as Environmental Contaminants of Emerging Concern: Potential Hazards for Human Health
This review covers how microplastics and nanoplastics enter humans through food, air, and skin contact, accumulating in the body over time. Inhaled particles can damage the lungs from the upper airways down to the deepest air sacs, and prolonged exposure has been linked to chronic inflammation, autoimmune disease, atherosclerosis, and cancer. The authors call for source reduction, material substitution, and better filtration to reduce exposure.
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.
Atmospheric microplastics: exposure, toxicity, and detrimental health effects
This review summarizes what is known about microplastics in the air, including their sources, how they travel, and their effects on human health when inhaled or swallowed. Airborne microplastics come from synthetic textiles, road dust, construction materials, and industrial processes, and can trigger inflammation and oxidative stress in the lungs and other organs. The authors conclude that atmospheric microplastics represent an underappreciated route of human exposure that deserves more research and regulation.
Microplastics inhalation and their effects on human health: a systematic review
This systematic review examines how breathing in microplastics affects human health. It finds that airborne microplastics can reach the lungs and may trigger inflammation, oxidative stress, and respiratory issues, with workers in textile and plastic industries facing the highest exposure levels.
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.
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.
An emerging class of air pollutants: Potential effects of microplastics to respiratory human health?
This review explores the emerging concern that airborne microplastics can be inhaled by humans, potentially causing adverse effects on the respiratory system. Researchers compiled available data on the concentration, size, shape, and chemical composition of microplastic particles found in urban air. The findings suggest that airborne plastic debris represents a largely understudied class of air pollutant with potential implications for human health.
Air Pollution Microplastics with the Potential Risk of Lung Disease: A Systematic Review
This systematic review of 20 studies found that airborne microplastics, present in both indoor and outdoor air, can reach deep into the lungs when inhaled. Their accumulation in lung tissue may cause oxidative stress, inflammation, and damage to the lung's protective lining, raising concerns about respiratory diseases from chronic exposure to plastic-contaminated air.
Microplastics, potential threat to patients with lung diseases
This review examines the potential threat that airborne microplastics pose to people with existing lung conditions, noting that these particles have been found in human lung tissue and sputum.
