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.

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.

Health outcomes attributed to inhalation of microplastic released from mask during COVID-19 pandemic: A systematic review

This systematic review examined how face masks worn during COVID-19 release microplastics that can be inhaled. The most common particles were polypropylene fibers smaller than 300 micrometers. Inhaled microplastics were linked to oxidative stress, inflammation, DNA damage, and potential cancer risk. These findings highlight a lesser-known health trade-off of widespread mask use during the pandemic.

Silent invaders: the role of MPs on epithelium inflammation and damage in airway diseases

This review examines how inhaled microplastics and nanoplastics interact with airway epithelial surfaces and trigger inflammatory, oxidative, and structural changes that may contribute to respiratory diseases. The study describes how these particles activate key inflammatory pathways such as NF-kB and PI3K/Akt/mTOR, potentially worsening conditions like asthma and COPD through enhanced barrier dysfunction, oxidative stress, and disrupted tissue repair.

Inhaled microplastics and lung health: Immunopathological effects and disease implications

This review examines the molecular mechanisms by which inhaled microplastics damage lung health, focusing on oxidative stress, inflammation, and immune disruption. Researchers found that microplastics trigger reactive oxygen species production, deplete antioxidants, impair mitochondrial function, and compromise immune defenses in lung tissue. The evidence indicates that microplastics may also act as carriers for other toxic pollutants, amplifying respiratory health risks.

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.

Newly Emerging Airborne Pollutants: Current Knowledge of Health Impact of Micro and Nanoplastics

This review examines microplastics and nanoplastics as emerging airborne pollutants, with sources including synthetic textiles, rubber tires, and furniture. Researchers found that while microplastics can reach the lungs, nanoplastics are small enough to cross into the bloodstream, potentially increasing health risks. Evidence from workers exposed to PVC and synthetic fibers suggests that long-term inhalation may lead to persistent inflammation and lung damage.
