Microplastics: Sources, Interactions, and Impacts in Humans
AI summary Read the abstract
Researchers reviewed how microplastic fragments smaller than 5 mm form from degraded consumer products and enter the human body through inhalation, ingestion, and dermal contact. The paper summarizes known and suspected health impacts across organ systems and identifies key research gaps in understanding long-term human exposure.
Microplastics (MPs) are miniscule plastic fragments formed as a result of the breakdown of larger plastic materials and a variety of consumer products. These minuscule particles, measuring less than 5 mm, may inadvertently enter the respiratory system,...

Sources of Microplastics in the Environment and Human Exposure Routes: A Review
AI summary Read the abstract
Researchers reviewed the major sources of environmental microplastic pollution — dominated by textiles, tires, and urban dust — and catalogued the primary human exposure routes via food, inhalation, and skin contact, noting that airborne MPs are an underestimated risk because fine particles can bypass respiratory defenses and penetrate deep into the lungs.
